Hey everyone! I'm at my friend's place and we ran into an issue after swapping out his old power supply (which was about 9 years old) for a new one – a Be Quiet Pure Power 12 M. Before this, my friend had some GPU problems, and we thought upgrading the PSU would be a good move instead of spending a lot on a new GPU right away. We disassembled everything for cleaning and after putting it all back together with the new PSU, we found that none of the system fans were spinning (except for those that are directly powered by the PSU). The motherboard's LEDs weren't lighting up, and we couldn't even power off the system using the button. We got debug error codes 60 or 80, but those didn't indicate much. We then tested the old PSU, and while everything powered up correctly, we still had no video output. We also tried the onboard graphics without the GPU, but ended up with the same result. We've already cleared the CMOS and tested the RAM sticks in different configurations. The cleaning involved just dry paper towels, a vacuum, and some brushes, and everything seems physically intact without any visible pin damage. His setup includes a Gigabyte GA-AX370 Gaming 5 motherboard, a Gigabyte RTX 3060 graphics card, a Ryzen 9 5900X CPU, and 2x16GB HyperX Fury RAM. I'm starting to wonder if the new PSU is faulty since the old one didn't provide video output either. Any ideas on what might be going on?

I’ve had similar experiences where a new PSU didn’t play nicely with older gear. It could be that the PSU isn’t compatible with your friend's motherboard or there's a grounding issue causing the no-boot situation. Have you checked all your connections, particularly the CPU power? Also, consider testing with just the motherboard, CPU, and one stick of RAM to eliminate other components.
It seems like the motherboard might be the issue here. I’ve got a similar setup with an X370 board and I noticed that mine had some damaged traces, but it still managed to post most times. You might not have noticed the damage, so it's worth checking the board closely again! Also, if your debug LEDs are showing 60 or 80, it might be worth looking into any particular issues your board has during booting. Good luck!
Thanks for the tip! I’ll take another look at the board for any hidden damage. Hopefully, that’s the culprit!
Good point! I’ll try powering it up with just the essentials. If it still doesn’t work, we’ll know we might need to look at the motherboard more seriously.
