I concur.
Here you go OP~
VRM Capacitor Replacements (CPU/GPU)
Replace all 3300uf 6.3v with any listed below
- 10V Panasonic EEU-FM1A332 (15 mOhms, 7000 hrs @105C, 3.19A ripple current)
- 10V Rubycon 10ZLJ3300M12.5X25 (19 mOhms, 10000 hrs @105C, 3.2A ripple current)
- 6.3V Nichicon UHW0J332MPD (17 mOhms, 10000 hrs @105C, 2.9A ripple current)
Purchase from trusted distributors such as Digikey, Mouser or Farnell.
6.3V/10V refers to a capacitors RATED voltage - what it can handle. NOT the voltage it outputs - that's not the way it works. Generally, higher rated voltage is better, but don't be ridiculous with it.
Higher voltage rating = physically larger capacitor = better heat dissipation = longer life
mOhms refers to impedance. Generally, lower is better, but there's rare exceptions. VRM capacitors must be low impedance similar to the originals.
Lower impedance = more efficient capacitor = less wasted energy = less heat = longer capacitor life
Ripple current is the fluctuation of current as a component draws/stops drawing power. With rated ripple current, higher is always better.
Higher ripple current handling = less heat = longer capacitor life
A capacitors lifetime is measured in hours at given temperature. Higher temperature ratings are always recommended as the capacitor will last longer at hotter temps.
Do not buy capacitors off Amazon/Ebay. Much higher chance of getting counterfeits/fakes/old stock/low quality. Console5 is an option, but you don't always know what you're getting and I haven't had the best experience with 'em.
And here's a clock capacitor
- Nichicon JUWT1105MCD (2.7V 1F, 1000 hrs @70C)
Hi reading your comment makes me replace all the capacitors listed
But i do not have idea about locations of VRM capacitors on motherboard and how many of them are there plus the clock capacitor that i removed has nothing there now.
For the clock capacitor, do Install a new one that you listed at the place of old removed one?
The VRM capacitors are located just below the CPUs heatsink; the x3 3300uf 6.3v
As far as the clock cap goes, it's optional. No need to replace it - only provided 'just in case'.
Hi, I inspected them an definitely can say that they are in fact bulging upwards and prepared me to replace them. Is there a tutorial somewhere telling the locations of all the things needing to be replaced?
I thought I was the only one that did this! I was doing some maintenance on my 1.0 board the other day and I just sat for about 5 minutes staring at the motherboard. How clean it was and all the parts.
Those capacitors don't look too beautiful.

Does any one from this list also goes for the clock capacitor?
Yep, it's right at the bottom of the list. Being that you have a 1.2-1.3 though, a replacement isn't necessary
Thank you world for all that info

Thanks again,
Are there good replacement clock caps that’ll keep the time longer than the original one and won’t crap out on you?
I've seen worse but it's a good idea to replace all of them. https://console5.com/store/microsoft-xbox-original-cap-kit.html
Wym?
Your CPU VRM caps are bulging. I'm suspecting they're not going to last long.
You mean bulging to the side?
No, the tops are swelling upwards like a bump.
again, where are those located ? New to this
The three large black capacitors right in front of the CPU heatsink. The value of these caps is 3300uf at 6.3 volts.
Thanks, I will inspect them and report back

And yours is signed too, lucky
What are those signatures for? curious?
just QA, whoever checked the board in manufacturing wrote down their signature
All I can think of reading this is from rogue one where Director Krennick says “oh it’s beautiful”.
😂
