PSU makes clicks while CPU fan remains stationary.
Hi, I just installed the cheap Asus PBZ77-V kit and connected it to a PSU that works fine. I have the CPU in but no memory yet, and the motherboard power and EATX12V are connected. When I connect the power switch, the PSU clicks but neither the CPU fan nor the PSU fan starts. If I remove the EATX12V and connect the switch, the CPU fan turns on but the CPU error light appears. The only illumination is the main power LED when I power on the PSU before bridging. I ran a paperclip test on the PSU and it seems okay. The CPU looks fine, but I need help figuring out if the problem is with the CPU or the motherboard.
Do you know the PSU is in good condition and you've checked it on another device? Testing it elsewhere confirms functionality. Skipping testing means risking a faulty PSU, so consider buying a used LGA 775 for around $30 and plug it in to verify it works. This helps confirm the PSU isn't actually defective.
You're welcome. I'm 99% confident the power supply is fine, since the seller confirmed it was removed from a functioning system. I didn't have the same assurance for the motherboard and CPU, which is why you're asking if it's possible to pinpoint the issue. Thanks for clarifying.
