I can help with that. What do you need advice on?

I shared some time ago about the PC not powering on, and I’m still trying to identify the cause. My thought is it might be related to power or PSU/connectors, especially since I have an ASUS Rog Strix B550-A with a Corsair RM 750x PSU. The motherboard has both an 8-pin and a 4-pin connector for CPU power, and I’ve been using only the 8-pin since installation. I’m curious if skipping the 4-pin could affect the CPU or motherboard, especially given occasional voltage fluctuations in my area. Could this be the problem?

What processor are you running? Because it supports both 8-pin and 4-pin connectors, the 8-pin version should suffice, though a BIOS issue might also be the cause.

I'm using a Ryzen 5 5600X with the latest BIOS during setup. It's been functioning well for a few months now, but recently started having issues.

Have you considered switching to a 4-pin connection instead of an 8-pin?

It seems the red light activates even without power, yet the device remains inactive when connected.

No, there were no visible issues with the power supply.

Check for any issues with the plug, wires, or power box if you're connecting one.

I connected it to an ups but also tested it directly in a wall outlet without success. There was no visible damage or burnt wires. I noticed that when the PC shut down due to a power outage, it didn’t start right away—sometimes I had to unplug it, wait a bit, and then try again, which worked this time. This process took about a day or two; I unplugged it for that duration and haven’t received any response since.

I'm not completely confident, but I've attempted what I believe might help. Perhaps the power disruption affected the motherboard or the power supply unit. I'm truly sorry, and aside from that, I don't know what could resolve the issue or its cause.

Great, I understand the situation. I’ll check the PSU to confirm the issue, unless it’s clear there’s another problem. If not, I’ll avoid purchasing a new motherboard until the cause is identified.
