[SOLVED] My PC Cuts Power and restarts when I try to load certain games. Could I please get some help?

[NathBurk]

I built a pc earlier in the year and it's all been well and good but for whatever reason when I load particular games my pc will immediately cut power and restart.

It happens consistently when I try to load modern warfare. It's always as I press the play button, it never makes it to the games menu or the boot sequence. It used to happen with apex legends as well until a recent update and other games like overwatch/R6 siege run perfectly. I've checked in the event viewer and it shows the problem being kernel-power 41 (63).

My system specs are:

AMD Ryzen 7 5800x
RTX 2070 Super
ROG STRIX B550-I GAMING
2x16gb DDR4
Samsung SSD 970 EVO plus 2TB NVME
1 TB SATA SSD

It's built in the NZXT H1 case (I've had the Riser cable replaced so that's all good) which has a 650w GOLD PSU. From my understanding that should be enough to run my system. My system temps are all normal and it runs everything smoothly. It's just for whatever reason it will cut power like it's being physically removed then it will restart.

From what I can gather it's the PSU. Would just like some help if it is something I can fix without purchasing new parts. Any help would be great, Thank you

650 seems a little tight. you could try under volting the 2070 and down clocking a bit and locking the 5800 to base speed/voltage. Sometimes PSUs only provide 500W on 12 volt rail, 100 on the 5V rail and 50 on the 3V rail and call it a 650W power supply. Where as other PSU will provide 650 12V 120 5V and 75 3V and call it a 650W power supply.

My money is on the PSU. You may have lost the lottery and actually got a 600W. I had a 10 year old 750W that did the exact same thing. Replaced with a 1200W (for plat and efficiency) and it went away.
