PSU failure beep code on working PSU

[TheCCCPC]

Hey guys!

I am having an issue with my Gigabyte Z97-SLI. Every time i power on, it gives the "PSU failure" code and refuses to boot. I've breadboarded the motherboard and also hooked up the PSU to a spare board I have. The PSU works on the second board but not the first.

Does anyone have any ideas how to fix?

Edit: All fans turn on, card fans spin, hard disk moves and mobo lights flash on power up. Then CPU fan turns off, mobo lights turn off, and it gives the beep code.

Thanks!

Is this a new board or did this issue just start with your system that you’ve had a while?

One I've had a while. I was removing a hard drive and decided to redo my cable management. After I did that, the issues began.

Check your 24 pin and ensure it’s seated. Also, make sure your CPU power isn’t loose or a PCI power connector.

I've checked and double-checked the 24 pin, 8 pin, and all other plugs. All are seated and have no give.

Ok, so since you know the PSU works with other boards and the connections are solid and since you’ve tried moving hardware around and and even breadboarded it I would say the issue has to be with the motherboard.

Check the board for bulging capacitors or oozing brown sludge from capacitors. Check for broken or fried solder points on the power connectors.
