Broken Power Supply Unit

[Jacob Rawson]

Hello,
Please tell me if I am wrong to post here but I'm new.
So i recently spripped my old PC for parts and decided to ruen the PSU into a bench power supply but I accidentally shorted the green and blue wire (-12v) not the black wire (ground) together, and now the power supply will not work at all to do anything. Has anyboday done this stupid mistake too and if so can anyone think how to fix it?
Thanks in advance,
Jacob

Open it up and look for a glass fuse soldered into the power supply board. If it's blown, replace it. There's a fair chance this is the only problem.

Otherwise, it gets a lot harder, and you may be better off calling the supply a loss.

I can not find a glass fuse on the PCB, so it looks like ill just have to dump the supply.
Oh well
