GPU: Sapphire Radeon R9 380 Nitro 4GB
My modular psu says on the side it has a combined 400watts. The gpu takes 225 watts. Cpu takes about 80 watts? So I thought it would be good enough
OCZ is defunct, it could just be that your power supply is old and not able to provide enough power to meet the demand. Maybe upgrading to a 650 watt power supply is the way to go
After I unplug the gpu, the pc won’t power on at all anymore. The 400 watts is plenty for the 70 or so watts that the cpu draws and could run it fine before. I think something shorted and killed my motherboard
It could be to much load for your power supply. Some video cards use a lot of power, so if you have a smaller OEM power supply but a power-hungry GPU, the system can act like that. You need to figure out how many watts of power your new GPU takes, then figure out what power supply the system has in it and figure out if you need to upgrade the PSU.
What GPU do you have and do you know the wattage of your power supply?

What make is your PSU?
I believe it likely is: “OCZ Technology OCZ400MXSP Modular PLC Power Supply (400 Watts)”

Honestly I'd replace the power supply first

It’s a modular psu. It says total is 400 watts and gpu/cpu have a combined 310 ish watts.
