Are you experiencing issues with your PSU?
Are you experiencing issues with your PSU?
My PC frequently restarts despite the system reporting memory overclock disabled and XMP not enabled. It still shuts down randomly, even after running stress tests for 30 minutes. Restarting occurs unpredictably, and I've reset the CMOS but the issue persists. The PC has been using the same PSU for a year, and once it restarted, it tripped my short circuit breaker. Here are the event viewer logs:

Specs: Windows 11 Latest, CPU I5 13400f, Motherboard MSI PRO B760M-A DDR4 wifi (no BIOS updates), GPU Asus Dual RTX 3060ti V2 OC, RAM Team Delta RGB T-Force 32GB 3600Mhz DDR4, SSD Nvme Crucial P5, PSU Cooler Master V750 Gold V2.
I’m considering replacing it with a Corsair RM750x.
Welcome to the forums, newcomer! How are you managing the processor cooling?
Motherboard: MSI PRO B760M-A DDR4 wifi - never updated the bios
What BIOS version do you have installed? The current one is 7D99v1C. I recommend updating it and then resetting your CMOS. To do this, disconnect from your display and power source, remove the CMOS battery, hold the power button for 30 seconds, then replace the battery after about half an hour.
Be careful, you’ll also need to update your ME (management engine) firmware. Please refer to the BIOS notes or description for more details.
It is of good quality, fully modular with a 10-year warranty, and also offers 80+ Gold efficiency. The PSU in question is near the line between low and average performance. Therefore, the random reboots are probably caused by the subpar power supply you're using. Another cause could be overheating from CPU or GPU, though this wouldn't trigger the circuit breaker. A faulty PSU might be responsible. Consider replacing it to eliminate this issue.
I have already cleared the CMOS, but I still can't power on the PC and updating the BIOS isn't working.
The GPU/CPU temperature is below 70 degrees Celsius, indicating it is not overheating.
I meant to reset the CMOS after updating the BIOS. If your BIOS is damaged, clearing the CMOS won't fix it, even with repeated attempts. Did you see the event viewer log during startup?
If your PC won't turn on, consider getting a stable PSU instead of borrowing one.
Without the PSU part number it's hard to identify the exact model, as Cooler Master offers various units named V Gold and V2 Gold. I checked the TH's PSU tier list from a past version (archived link), which still contains the information. V2 Gold non-modular and V2 Gold are both in Tier B, low priority units. To avoid confusion about PSU models, it's best to include the part number. For example, my PSUs are:
- Seasonic PRIME 650 80+ Titanium (part number: SSR-650TD), now called PRIME TX-650.
- Seasonic PRIME Ultra 650 80+ Titanium (part number: SSR-650TR), now called PRIME TX-650.
- Seasonic Focus+ 550 80+ Platinum (part number: SSR-550PX), now called Focus PX-550.
If your PSU is Tier A, please send the RMA, as there can be issues even among high-quality units.
