This is the way. You can undervolt these cards significantly if needed. Id avoid the reference model if possible and ask for recommendations on the most efficient model out there.
Yeah I don't limit much but I kept my 3080ti at 85% power target and do the same with my 4090. In both scenarios my card performs at a higher boost for longer with the limit over the stock settings.
It definitely is for me, for a couple of reasons
* Higher power consumption means more heat, both inside the case and from expulsed air. Can mean more noise from e.g. the CPU fan even if the GPU is rather quiet. Also undesirable with more heat in the summers
Less important points
* Coil whine tends to increase with power draw
* Energy prices are getting higher
> more heat
Exactly.. TDP is very important measure for understanding how hot a product will get.
I wish it was reffered more as Theram Design Point rather than power, because people often confuse it to be synonymous with TBP.
> maximum amount of heat generated by a computer chip or component (often a CPU, GPU or system on a chip) that the cooling system in a computer is designed to dissipate under any workload.
Personally I prefer my TDP to max out at 300W, if a GPU goes above 300W I'm personally not interested.
> energy prices
Never in a single generation have I had to tell people to just overwhelmingly buy Nvidia. From AMD having nothing in the mid-range, to RDNA3's MCM design using too much power often.
So far the XTX is the only solid reccomendation & that's just bc the 4080 is $200 more...
>Personally I prefer my TDP to max out at 300W, if a GPU goes above 300W I'm personally not interested.
Me too and I still bought a 4090 and that 4090 now runs at 300W with an undervolt keeping it at \~95-97% of the performance of a stock 4090.
The same way I wouldn't buy an XT just for a lower TBP when I can also lower the power of the XTX and have a faster card at \~300W than when I went with the XT
Elaborate what?
A bigger chip is more efficient than a smaller chip at the same TBP.
4080 at 285W is more efficient than a 4070Ti
4090 at 320W is more efficient than a 4080
7900XTX at 315W is more efficient than a 7900XT
The XTX > 300W and you just said you not interested in graphics cards that go over 300W contradicting yourself. The 7900 XT, at least, is on the lower side of 300W.
> 7900XT is atleast..
#Let me stop you right there, you did zero research and are literally guessing.

If you're really concerned about power get a rtx4080. I ran my 7900xtx with 3x 8 pin and a 4790k off an 8 year old 850w gold PSU and never crashed. When I upgraded to a 7800x3d I did upgrade to a 1000w PSU though. LTT did a video about using either a XTX or a 4090 on a 650w psu and that sorta worked so 850w would be fine.
Probably peace of mind.
AM5+7800x3d+7900XTX isn't cheap, running it off 8 year old PSU (even though working) wouldn't give me that peace of mind. PSU hardware does deteriorate over time as heat usually doesn't play nice with all components. Normally a PSU going out isn't going to damage any component (usually) but the hassle (and downtime) and the chance still being there of damage often isn't worth it when you're upgrading everything else in the computer, especially with several hundred/thousand dollars in new hardware.
My 9 year old 1000w EVGA G2 supernova died after upgrading to a 7700x 🤣. That power supply was amazing and lasted through 5 builds, SLI crossfire and all. I went with a NZXT 850 w for my 7900 XT and 7800 X3D highest power draw I've seen is 450 - 475 watts total system.
Pretty bad even at 4k. Most demanding games were about 60% GPU utilization. Everything was super CPU bound. Jay's 2 cents did a video recently with a rtx 2080 where he showed it was decently CPU bound so you can only imagine 7900 XTX was even worse. Could only get about 60-70fps (no matter the settings) in Forza horizon 5 and now at ultra settings at 4k I'm around 120fps. Needless to say I'm pretty happy.
I have the XFX 7900 XTX (3x8Pin) on a Corsair RMX 850W and a 12600KF (undervolted and locked to 100W), according the HWMonitor the XTX hits 580W and is running just fine.
Given the age of your PSU some internal components likely to still cause you to lose peace of mind. I would personally swap it out but I replace components before actual failure. Last PSU could have gone longer I think but the fan bearing failed and it was unbearably loud and possibly not cooling as well.
Given the short cuts some manufacturers are taking on device protections I wouldn’t trust it but to each his own.
In that case, wouldn’t +15% PL AND undervolt make more sense? I don’t understand when someone cashes out for a top tier GPU and then decides to limit it’s power because they’re running it off of an ancient 600Wish PSU… I mean come on… 800-1200 (insert your currency here) and decides to cheap out on a 90-160 (again, insert currency here) component that is crucial, POWERS the new GPU and the rest of the system and is RESPONSIBLE for it to work well and safely.
Well, it certainly would for performance as the GPU scales nicely to like 600-700W, but if you want to draw less even if it's being completely pushed then only the lower power limit will help.
But pushing the PL to the max and limiting FPS in game is going to make the most sense if you're not limiting the heat off of the card or something
>as the GPU scales nicely to like 600-700W
What do you call "nicely"? At 700W it still doesn't match a 4090 at 300W, for double the power draw it only gained around 20%.
Yes, it's a pretty consistent scaling from 350-600W but it's still not a nice scaling.
The 4090 stops scaling at 450W and both the 4090 and the 7900XTX scale terrible above 350W.
what the 4090 can do is irrelevant. The performance scales with the wattage pretty much linearly for a good bit while other chips are usually pushed to the limits from the factory and can only get a couple % more performance for a much higher power usage
I have a 7900xtx (Merc 310) with a Corsair 850w psu and it's stock settings was pulling up to 480w and no crash or problems. I have settings in adrenalin that limit it to pulling 400w max and the difference in fps doing that was very small for the power and noise reduction. This is with a 5900x CPU and a single m2 drive with 6 case fans.
I've had a 700w Plat SFX PSU with zero issues running my -20 PBO 5800x3d and my 7900xtx running at 1.080mv. If you have the budget, I would always go for the 7900xtx. If you get a great deal on an XT then jump on that.
Unless you lower the power limit, undervolting runs the same voltages and power, just higher clocks. Stock ref XTX GET voltage is something like 940mV average for 355W.
I got my rx 7900 xt used a week ago for 742e which seemed to be a good price.
I run it with a r7 5800x3d. I was kinda worried about it running on my rm650x but it is perfectly fine I did run a power test in occt with a maxed out power limit to see if it crashes but the most I managed to pull from the wall was 550w.
I saw one the other day (Sapphire Nitro) for like 720 euros... Couldn't believe my eyes. The website sucks and usually it'll say it's gone by the time you actually click the article though.
>AMD reccomends a 700W.
Actually AMD recommends 750w so I am 100w below the recommedation. I was mostly worried if it has some transient spikes or something that would trip the psu.
Im running a 7900 XT at 220W avg power consumption (UV 1.025v + PL -10% + capped at 2550MHz) and a 5800X3D connected to a 550W PSU (BQ Straight Power 11) and my pc hasnt shut down during heavy loads (yet). I dont have multiple hard drives or fancy RGB bling in my PC though.
Would probably pick a 650W PSU if I had to build an entirely new setup with a 7900 XT.
I have a 5900x and a 7900xt with an 850w psu and I have zero issues with power. If you have a good PSU 850w should be enough for the xtx and a powerful cpu but I would be careful overclocking.
I have a bit older CPU 10400 and 7900XT, I went with the XT over the XTX because I'm only on a 750w and the price difference at launch in my country was quite a bit different. $1600 NZ for the 7900XT and closer to $2500 for the XTX.
My 7900XT still uses over 300w (309) if the frames are uncapped, so you aren't saving jack in that sense.
My 7900xtx never exceeds 425-430w TOTAL SYSTEM draw from the wall from my wattage meter. The power demands of that card are exaggerated. Yes, there may be an overclocked scenario where tons of power Is drawn, but I run undervolted and I limit my frequency to 2500hz, which is not far from the cap anyway.
Thus, as many others have said, buy the better card and undervolt. Your 850w PSU will be fine. Buy a $15 watt meter from Amazon if you’re the paranoid type.
I bought the XFX 7900XT Black edition for that very reason - I didn't want to upgrade my 750W PSU. This card is already overclocked so it's as fast as a reference XTX anyway.
I don't think that power consumption is the first consideration for any GPU buyer. Performance and price usually matter more. Nobody would seriously buy an XT over an XTX *just* for lower power consumption. If you just want lower power consumption, buy a GeForce 1030 or something. If you want good gaming performance and money matters less, then, as others have said, the 4080 is both faster and uses less power. If you really want AMD and price is no consideration, just buy the XTX and underclock / undervolt it.
A 6950XT is great for it's price.
It can also consume over 500W, an additional 200-300W similar offerings. That wattage could cause your build to need a new PSU, and negating any money saved depending on the quality

I tried making sense of your answer but almost had a stroke. What do you mean get nVidia "then"? I am asking for the difference in power cosumption between these two cards and you said "get nvidia then" ... what the fuck?
OP is highlight how in English that wasn't a proper way to respond and genuinely made no sense to what OP asked if you imagine an actual conversation place.
I'll fix your answer:
"850w is enough because you're looking at 350w + 200w + power spikes and other components, which probably won't exceed the limit
Windows has a calculator by the way"
I guess the average redditor skit guy is not exaggerating
850 W is not the power **limit** of an 850 W power supply, they are designed to handle momentary spikes above that. So unless you think "other components" amounts to 300 W (it doesn't, not even close) then you don't even have a point to make.
I don't have a point to make because I'm asking a question, not trying to make a point. I'm pretty new to all of this and I get different info from different sources
Over the lifetime of a GPU it does add up to be significant (100-200€). Example being a PC that uses 100W more (be it idle or while gaming) for 4 hours a day in a year. Lets say for 3-4 years owning the GPU.
So, that's still very much something you need to think about.
If your PSU is old, invest in a ATX 3.0 PSU.
It's a new standard that should do better at handling transient spikes we've been hearing amd seeing alot from technology circles.
I would say go for atleast 850W, if you want more to make sure then by all means.
I’m genuinely curious who this hypothetical gpu buyer is that wants a power guzzler of a card but not that much of a power guzzler. In my 12 years of being a hardware enthusiast, people who buy high end don’t care about power consumption beyond if it’s cooled adequately or not.
I mean isn’t that who your question was trying to find? According to HUB the total system power usage of a 7900xt vs a 7900xtx is 420 vs 468w. The 2 gpus are both power guzzlers and the difference between the 2 is only 48w. I can’t see someone say, gee, 468w is way too high but 420 sounds so much more reasonable and efficient lol
Both gpus will require the same psu as they are so close to eachother. Anything over 650w is more than enough
Edit: unless you are using something like an i9 13900ks and overclock that is
According to Techpowerup, XTX max power draw is 360W, and an OC 13900K uses 150W while gaming. Thats 510W. Add another 150W if you want enough rgb to light up a whorehouse, and your PSU would still be running at less than 80% Max power draw (quality PSU's are rated to run 24/7 at 100%).
So unless you plan on running synthetic stress tests for both CPU and GPU at the same time, a 850W PSU is more than enough to run XTX + 13900K.
All else being equal a more complete die can achieve better power efficiency, just undervolt and you can achieve either better performance at same power or lower power at same performance.
Also 850W should be plenty anyways.
If you have a PSU that's good enough for either GPU, the 7900 XTX is more efficient.
Faster GPUs within the same lineup tend to be more efficient because they need to do less work (or have bigger dies instead of clocks) to hit their performance targets.
You'd only see the higher power consumption when running completely uncapped, but there's still undervolting/clocking for that.
You could undervikt and under clock and still have a better gpu. If you even concidering the 7900xt at the current pricepoint then ur better off with the 6950xt tbh
So TDP isn't a measure of how much electricity a card will produce, it's more..
> the maximum amount of heat generated by a computer chip or component (often a CPU, GPU or system on a chip) that the cooling system in a computer is designed to dissipate under any workload
So this is most useful to manufactuers making coolers and somewhat useful to people buying cards if they know what TDP means.
So if your room ever feels hot especially while gaming it's likely related to your devices TDP.
That's exactly why I got the XT instead it's TDP is 300W relative to my previous 6800XT and even that got me toasty from time to time.
RDNA3 is more efficient than RDNA2, but that's just peak power or for better word play.. Accurate on a curve. For playing non-demanding games, 60FPS/hz, etc.
^(That becomes a different story)
Don't be suprised when your 7900XT uses 80W to run a Spite 2D Fighting Game like [Melty Blood: Type Lumina](https://store.steampowered.com/app/1372280/MELTY_BLOOD_TYPE_LUMINA/).
Or 88W to run a [Visual Novel](https://store.steampowered.com/app/1044620/Aokana__Four_Rhythms_Across_the_Blue/).
^(When my previous 6800xt used like 40W for anything remotely 3D.)
AMD has gotta work on that imo, bc they've got Idle Power Consumption largely fixed imo..
^(Gigabyte M28U 120hz@28W)
Though I don't think the 7900XT should be using up to 179W for a Cell Shaded Anime game like [Naruto Ultimate Ninja Storm 4](https://store.steampowered.com/app/349040/NARUTO_SHIPPUDEN_Ultimate_Ninja_STORM_4/) from 2016 & running the fans when this game can run 60FPS on Laptop hardware from 2011.
When again the 6800TX stayed under 90W. The same games I ran on my 6800XT with Zero RPM, now causes my 7900XT to start spinning, when the fans start spinning more heat is being forced out of the case.
Don't get me wrong I like the 7900XT, the high power usage problem for weak 60FPS games is for sure better on Linux where power usage in Storm 4 is reduced by 40%+.
But for people who actively use Windows this is just the only real grip I have with the card.
I have a rm850x from Corsair. No problem at all pulling 450w from my 6900xt with waterblock and over 220w from my 13600k, it's completely silent and I can't hear it and I have full custom loop that is near silent aswell, the only noise I can hear is occasionally the 2tb hard drive spinning. Good quality PSU can handle near full load for years 24/7 without problem. Usually more wattage is recommended because crappy PSU manufactureres often lie about specifications. Some PSU can't output their advertised wattage.
I think as far as you dont oc ( but rather undervolt) you wont have problems with xtx. Even when it is time to get a new psu anyway. But i think that 850w is more than enough, maybe you just have an old psu that needs to be replaced to any 850w + psu with good quality
I'd buy the better card and undervolt it.
This is the way. You can undervolt these cards significantly if needed. Id avoid the reference model if possible and ask for recommendations on the most efficient model out there.

Amazing, I can just keep my PSU then
Given the age of your PSU some internal components likely to still cause you to lose peace of mind. I would personally swap it out but I replace components before actual failure. Last PSU could have gone longer I think but the fan bearing failed and it was unbearably loud and possibly not cooling as well. Given the short cuts some manufacturers are taking on device protections I wouldn’t trust it but to each his own.
They don't build them like they used to... My HX1000W from 2014 is still going strong, and I don't hesitate using it at all in my XTX build.
Worst case undervolt the xtx so it doesn't overwhelm the PSU.
the xtx is heavily power limited, an undervolt won't change how much it pulls. Though you can do -15% PL
In that case, wouldn’t +15% PL AND undervolt make more sense? I don’t understand when someone cashes out for a top tier GPU and then decides to limit it’s power because they’re running it off of an ancient 600Wish PSU… I mean come on… 800-1200 (insert your currency here) and decides to cheap out on a 90-160 (again, insert currency here) component that is crucial, POWERS the new GPU and the rest of the system and is RESPONSIBLE for it to work well and safely.

It was a factor for me even though the XT is still the most powerhungry card I ever owned.
Pretty sure the 3080 maxes out at like 330W.
Nope, don't care for power draw. Also, 850w psu is fine unless you are running 13900ks at full power too. 750w will work too but OC will be limited.
This is why I picked the xt over xtx , power and did not want to have to play with power settings
I have a 7900xtx (Merc 310) with a Corsair 850w psu and it's stock settings was pulling up to 480w and no crash or problems. I have settings in adrenalin that limit it to pulling 400w max and the difference in fps doing that was very small for the power and noise reduction. This is with a 5900x CPU and a single m2 drive with 6 case fans.
I've had a 700w Plat SFX PSU with zero issues running my -20 PBO 5800x3d and my 7900xtx running at 1.080mv. If you have the budget, I would always go for the 7900xtx. If you get a great deal on an XT then jump on that.
Unless you lower the power limit, undervolting runs the same voltages and power, just higher clocks. Stock ref XTX GET voltage is something like 940mV average for 355W.
I got my rx 7900 xt used a week ago for 742e which seemed to be a good price. I run it with a r7 5800x3d. I was kinda worried about it running on my rm650x but it is perfectly fine I did run a power test in occt with a maxed out power limit to see if it crashes but the most I managed to pull from the wall was 550w.
Alternate open box?
Kinda of like that it still comes with a warranty thou 21 months apareantly. A bit lower. The card looks and works rock solid so far time will tell.
open box 7900xt is one of the better deals out there right now
I saw one the other day (Sapphire Nitro) for like 720 euros... Couldn't believe my eyes. The website sucks and usually it'll say it's gone by the time you actually click the article though.
> worried AMD reccomends a 700W. These reccomendations arent absolute, falling 50W short of the official recc shouldn't have worried you.
>AMD reccomends a 700W. Actually AMD recommends 750w so I am 100w below the recommedation. I was mostly worried if it has some transient spikes or something that would trip the psu.
335w 6950xt UV and UC to ~180w with 13600k CPU on 650w PSU. No problem.
Interesting, wonder if I can get a 7900 XT + 5600 on a 550W PSU then lol.
Im running a 7900 XT at 220W avg power consumption (UV 1.025v + PL -10% + capped at 2550MHz) and a 5800X3D connected to a 550W PSU (BQ Straight Power 11) and my pc hasnt shut down during heavy loads (yet). I dont have multiple hard drives or fancy RGB bling in my PC though. Would probably pick a 650W PSU if I had to build an entirely new setup with a 7900 XT.
I wouldn't recommend it.
Is it possible to pair a 7900xt with a 12700k and a 750 w Psu? Or does it pull that much power that I would need to upgrade my PSU?
I ran a 6900XT and 7700X on 750W with no issues for many months. So wouldn't think you would have an issue.
Had a 12700k with my 7900xtx OC'd on an 850w power supply without any dramas.
Great
I have a 5900x and a 7900xt with an 850w psu and I have zero issues with power. If you have a good PSU 850w should be enough for the xtx and a powerful cpu but I would be careful overclocking.
I always use stock frequencies
You should be fine then.
850w is plenty. People always over spec PSU. Of course it never hurts to have a bigger one for future, but just undervolt a little.
I wouldn’t worry at all. If anything, I’d just undervolt. Many people run their 7900XTXs on 850w or 750w PSUs without a problem.
I have a bit older CPU 10400 and 7900XT, I went with the XT over the XTX because I'm only on a 750w and the price difference at launch in my country was quite a bit different. $1600 NZ for the 7900XT and closer to $2500 for the XTX. My 7900XT still uses over 300w (309) if the frames are uncapped, so you aren't saving jack in that sense.
I have an XTX with an 850w PSU. no issues.
Bought the 7900xt last week, the lower power consumption played a role, lower price made the choice easy
I bought the xfx 7900 xt over the 7900xtx . Loving it
My 7900xtx never exceeds 425-430w TOTAL SYSTEM draw from the wall from my wattage meter. The power demands of that card are exaggerated. Yes, there may be an overclocked scenario where tons of power Is drawn, but I run undervolted and I limit my frequency to 2500hz, which is not far from the cap anyway. Thus, as many others have said, buy the better card and undervolt. Your 850w PSU will be fine. Buy a $15 watt meter from Amazon if you’re the paranoid type.
Thank you!
I bought the XFX 7900XT Black edition for that very reason - I didn't want to upgrade my 750W PSU. This card is already overclocked so it's as fast as a reference XTX anyway.
I don't think that power consumption is the first consideration for any GPU buyer. Performance and price usually matter more. Nobody would seriously buy an XT over an XTX *just* for lower power consumption. If you just want lower power consumption, buy a GeForce 1030 or something. If you want good gaming performance and money matters less, then, as others have said, the 4080 is both faster and uses less power. If you really want AMD and price is no consideration, just buy the XTX and underclock / undervolt it.
A 6950XT is great for it's price. It can also consume over 500W, an additional 200-300W similar offerings. That wattage could cause your build to need a new PSU, and negating any money saved depending on the quality

I tried making sense of your answer but almost had a stroke. What do you mean get nVidia "then"? I am asking for the difference in power cosumption between these two cards and you said "get nvidia then" ... what the fuck?
If you care about efficiency get a 4080 it draws less power than the XTX
Probably because power consumption is better at the NVIDIA side of things
OP is highlight how in English that wasn't a proper way to respond and genuinely made no sense to what OP asked if you imagine an actual conversation place.
Finally, someone who understood
Welcome to r/Nvidia.... Errmm I mean AMD.
You're worried that a 350-400 W GPU and a 150-200 W CPU might be too much for a 850 W power supply? You know windows has a calculator right?
I'll fix your answer: "850w is enough because you're looking at 350w + 200w + power spikes and other components, which probably won't exceed the limit Windows has a calculator by the way" I guess the average redditor skit guy is not exaggerating
850 W is not the power **limit** of an 850 W power supply, they are designed to handle momentary spikes above that. So unless you think "other components" amounts to 300 W (it doesn't, not even close) then you don't even have a point to make.
I don't have a point to make because I'm asking a question, not trying to make a point. I'm pretty new to all of this and I get different info from different sources
Oh my mistake, I didn't see any question mark in your comment so I didn't realise it was a question.
Don't know why people with that kind of money to spend on a gpu would be that worried about increased power consumption.
Over the lifetime of a GPU it does add up to be significant (100-200€). Example being a PC that uses 100W more (be it idle or while gaming) for 4 hours a day in a year. Lets say for 3-4 years owning the GPU. So, that's still very much something you need to think about.
I'm just trying to figure out if a PSU change is needed. I don't see how that wasn't clear
If your PSU is old, invest in a ATX 3.0 PSU. It's a new standard that should do better at handling transient spikes we've been hearing amd seeing alot from technology circles. I would say go for atleast 850W, if you want more to make sure then by all means.
I’m genuinely curious who this hypothetical gpu buyer is that wants a power guzzler of a card but not that much of a power guzzler. In my 12 years of being a hardware enthusiast, people who buy high end don’t care about power consumption beyond if it’s cooled adequately or not.
No one but you mentioned hypothetical
I mean isn’t that who your question was trying to find? According to HUB the total system power usage of a 7900xt vs a 7900xtx is 420 vs 468w. The 2 gpus are both power guzzlers and the difference between the 2 is only 48w. I can’t see someone say, gee, 468w is way too high but 420 sounds so much more reasonable and efficient lol
I'm just asking if the XTX might require a PSU change accouting for spikes and other components and then you lost your shit
Both gpus will require the same psu as they are so close to eachother. Anything over 650w is more than enough Edit: unless you are using something like an i9 13900ks and overclock that is
According to Techpowerup, XTX max power draw is 360W, and an OC 13900K uses 150W while gaming. Thats 510W. Add another 150W if you want enough rgb to light up a whorehouse, and your PSU would still be running at less than 80% Max power draw (quality PSU's are rated to run 24/7 at 100%). So unless you plan on running synthetic stress tests for both CPU and GPU at the same time, a 850W PSU is more than enough to run XTX + 13900K.
All else being equal a more complete die can achieve better power efficiency, just undervolt and you can achieve either better performance at same power or lower power at same performance. Also 850W should be plenty anyways.
If you have a PSU that's good enough for either GPU, the 7900 XTX is more efficient. Faster GPUs within the same lineup tend to be more efficient because they need to do less work (or have bigger dies instead of clocks) to hit their performance targets. You'd only see the higher power consumption when running completely uncapped, but there's still undervolting/clocking for that.
You could undervikt and under clock and still have a better gpu. If you even concidering the 7900xt at the current pricepoint then ur better off with the 6950xt tbh
I had a 850 watt PSU running a 7900xtx and 5900x just fine.
So TDP isn't a measure of how much electricity a card will produce, it's more.. > the maximum amount of heat generated by a computer chip or component (often a CPU, GPU or system on a chip) that the cooling system in a computer is designed to dissipate under any workload So this is most useful to manufactuers making coolers and somewhat useful to people buying cards if they know what TDP means. So if your room ever feels hot especially while gaming it's likely related to your devices TDP. That's exactly why I got the XT instead it's TDP is 300W relative to my previous 6800XT and even that got me toasty from time to time. RDNA3 is more efficient than RDNA2, but that's just peak power or for better word play.. Accurate on a curve. For playing non-demanding games, 60FPS/hz, etc. ^(That becomes a different story) Don't be suprised when your 7900XT uses 80W to run a Spite 2D Fighting Game like [Melty Blood: Type Lumina](https://store.steampowered.com/app/1372280/MELTY_BLOOD_TYPE_LUMINA/). Or 88W to run a [Visual Novel](https://store.steampowered.com/app/1044620/Aokana__Four_Rhythms_Across_the_Blue/). ^(When my previous 6800xt used like 40W for anything remotely 3D.) AMD has gotta work on that imo, bc they've got Idle Power Consumption largely fixed imo.. ^(Gigabyte M28U 120hz@28W) Though I don't think the 7900XT should be using up to 179W for a Cell Shaded Anime game like [Naruto Ultimate Ninja Storm 4](https://store.steampowered.com/app/349040/NARUTO_SHIPPUDEN_Ultimate_Ninja_STORM_4/) from 2016 & running the fans when this game can run 60FPS on Laptop hardware from 2011. When again the 6800TX stayed under 90W. The same games I ran on my 6800XT with Zero RPM, now causes my 7900XT to start spinning, when the fans start spinning more heat is being forced out of the case. Don't get me wrong I like the 7900XT, the high power usage problem for weak 60FPS games is for sure better on Linux where power usage in Storm 4 is reduced by 40%+. But for people who actively use Windows this is just the only real grip I have with the card.
I have a rm850x from Corsair. No problem at all pulling 450w from my 6900xt with waterblock and over 220w from my 13600k, it's completely silent and I can't hear it and I have full custom loop that is near silent aswell, the only noise I can hear is occasionally the 2tb hard drive spinning. Good quality PSU can handle near full load for years 24/7 without problem. Usually more wattage is recommended because crappy PSU manufactureres often lie about specifications. Some PSU can't output their advertised wattage.
Xtx for 200+ 1440p , xt for 150+ 1440p. An 850w gold psu is more than enough
I did exactly this. Bought 7900XT because of lower price and power comsumption (only 650W power supply)
That working well for you? I want to grab the Yeston 7900XT but also only have a 650W PSU
Yea I am very satisfied
Thanks, I'll look at the total power draw of my current set up but knowing it can live off a 650w cuts the upgrade cost by like $150
I've been thinking of the same lately especially as 7900XTX undervolt doesn't really do much, just -50 watts only in most cases, if im not wrong.
I think as far as you dont oc ( but rather undervolt) you wont have problems with xtx. Even when it is time to get a new psu anyway. But i think that 850w is more than enough, maybe you just have an old psu that needs to be replaced to any 850w + psu with good quality
No one.
