Question Computer Turning off in Demanding Games but Succeeds Stress Tests

[Zmac02]

I have been having an issue where my computer turns off while in certain games with higher system demands. I initially thought it was a power supply issue, so I upgraded my power supply, however, the issue still persisted. I tried reseating the RAM as well as swapping which slots they were in as well as putting each component and the system as a whole through a stress test. The stress test was successful and temperatures never went above 78 C, but the issue persisted. Any ideas for a possible solution?

My PC Specs are as follows:
OS: Windows 11 Home
CPU: AMD Ryzen 5 5600X 6-Core
RAM: 2x16 GB DDR4 Teamgroup T-Force 3600MHz
Motherboard: MSI B450M PRO-VDH Max
PSU: Corsair RM750e (750 Watts)

What software are you using to stress test the system?

What software are you using to stress test the system?

Aida64

What gpu are you running? Also what cpu cooler are you using?

Try running Intel burn test and see what your temps max out at.

My thought is you’re likely only stressing the cpu during aida64, but when you’re playing demanding games that your gpu is also having to draw more power and so between the power draw of your cpu and gpu combined that your power supply just can’t handle the draw.

My GPU is a Radeon RX 6650 XT, I knew I forgot something in the original post. My CPU cooler is a DeepCool AK400. In my final test using Aida, I ran a whole system stress test, including CPU, GPU, RAM, Drives, and FPU. The temperature panel showed maximum temperatures of 78 C for the CPU and GPU, and was largely stable for the 20 minute duration of the test as opposed to the system crashes occurring when playing games which usually happen within 5 minutes of launch.

Stress tests use all cores which limits how high they can go, games use fewer cores fully allowing them to go higher, if your mobo has PBO or any other sort of overclock going then it might push them more than they can handle.

You could try setting the ram to 3200Mhz and see if the issue persists

I would reset all bios settings to default to see if that changes anything

I reset the BIOS to default and updated it to the current version, changed the frequency of the RAM, and turned off PBO in the BIOS and still no luck. Is there a way to test each core of the CPU individually?
