Your computer is stopping unexpectedly.
I recently installed my system and encountered a problem where it would power off unexpectedly, especially during CS:GO sessions. The shutdown happened instantly with no warning or blue screen. Temperatures were normal, and CPU readings stayed stable during play. It's new hardware, so I'm trying to figure out what caused it.
It should be noted, though, that the 3000 series cards often generate significant spikes, leading to these issues. To eliminate doubt, consider getting a more powerful PSU (through purchase, borrowing, etc.) and observe if the problem resolves. This has been a widespread concern, especially for those with 3080 or higher models.
I picked the 750w because it meets my needs. They suggested a 650w for the 3070 model.
It seems the issue might be related to the power supply unit. If the system fails, can you restart it immediately or do you need to adjust the PSU connections? From what I've heard, a friend used an 850-watt PSU with an RTX 3080 that required a higher wattage unit, and switching to a 1 KW PSU resolved his problems.
Consider testing a stress test that uses both CPU and GPU simultaneously to check if the problem persists. Also, the lack of OCP on your PSU raises concerns about CPU VRM performance—especially since I had issues with Gigabyte B450 boards, though it's unclear if B550 models are affected. The VRM specs suggest it should support 125A, which should comfortably handle a 5800X. Download HWInfo to review the VRM temperature data (often referred to as VRM MOS).
