Computer randomly restarting during gaming

[Stealthdoze]

Hello, I am new to PC and just built my first PC. I haven’t had any trouble hooking it up and setting it up. Computer is fine while browsing, etc and basically not gaming. 
 

 

When I was playing a few games like RDR2 and Outer Worlds, the computer randomly shut down and restarted. No errors popped up, and event viewer says kernel power. 

 

 

I have checked the following:
- Cinebench test comes out fine 
- Memory test is fine 
- CPU and GPU is not overheating, temps are good 
- Voltage appears to be normal 
- Stats seemed normal right before computer shut off while gaming which happens a few minutes after actually playing the game. Not doing 4K or anything crazy and it was just those two games. 
- I’ve reseated the RAM, cooler, GPU just incase and the cables going to PSU. 
- Plugged computer into outlet directly thinking it was the surge protector 

 

 

Computer specs:
- Intel i9-13900k
- MSI Z690 Carbon Wifi motherboard 
- 32gb RAM (16x2) Corsair Dominator - 5600mhz
- Corsair 1000 watt 80+ platinum PSU
- Corsair iCUE H150i AIO Cooler (top exhaust)
- AMD Radeon RX7900 XT
- 3 Front intake fans (iCUE)
- 1 back exhaust fan (Corsair case fan)

 

 

I do have ONE pci-e cable coming from the power supply and the other end has TWO 6+2 pins. Could not using two separate cables be causing the issue?

Yes

But its not 100%

What temps and clocks are the cpu and gpu hitting?

I had this whole reply written out a day before and I seem to have found a solution that suggests it's a voltage problem. I seem to be facing these exact issues with very similar specs:

Spoiler

CPU: AMD Ryzen 7 5800X

GPU: XFX Speedster MERC310 RX 7900 XT

Mobo: ASUS ProArt Creator B550

Ram: 32GB (2x16 DDR4) Corsair Vengeance RGB PRO SL 3600mHz

PSU: Corsair HX1000i 80+ Platinum

 

If it matters, I have a TP-Link PCIe wifi adapter in PCIe slot 3, two M.2 SSDs, two 3.5 HDD, 6 Corsair 120mm LL Fans + Corsair H150i AIO, 1 Corsair 120mm SP for rear exhaust.

 

I plugged in my PSU cables the same way OP did. 

 

Based on everything I know, and considering I've torn the entire PC apart and reseated every last thing I could think of, I can't imagine it being anything hardware. Temps are all stable under load (CPU never maxed out beyond 82, GPU never beyond 65, tested with MSI Kombustor), and I can't imagine draw power being an issue with a 1000W PSU. 

 

Games played during sudden automatic shutdown:

COD Black Ops: Cold War

CODWFII/WZ 2.0

 

My "solution":

 

I updated Adrenalin to 23.1.1. In the Adrenalin app itself, I selected "Undervolt GPU" under "Performance -> Tuning", and then changed my gaming settings to enable FSR ("Gaming -> Graphics Subheading -> Radeon Super Resolution Enabled").

 

In my game settings, I turned the resolution down to 1080p and had FSR upscale to 1440p. No lag, no dropped frames, and power doesn't seem to spike above 250W. Frames stayed around 140FPS for Cold War, CPU and GPU times were 5ms, VRAM hovered around 16GB, RAM Util stayed around 75%.

 

That suggests to me that it's a power spike issue. It could be that the PSU is being randomly overdrawn during those transient spikes, it could be that the PSU is still within its limits but if you're plugged into a power bar or extension cord, your PC might be bottlenecked by it.

Power draw certainly can be a problem for a 1000W PSU with 13900K AND 7900 XT. Transient spikes for both could easily jump over 500W EACH as many reviewers already demonstrated. That's why when i build a system with 13900k i always put either 1300W or 1600W PSU. Unfortunately the 7000 series GPUs aren't as efficient as we all hoped would be.
