never opened a psu before. I want to discharge the capacitors of any residual juice. My idea was to connect a fan to one of the molexes and then bridge green to black with a piece of wire, to jump the psu. Will this work?
If not please explain the correct method. Thanks

A faster and better way would be to open up the PSU then hold up a resistor (say about 10ohms/800w to be safe) to the back of the PCB where the cap is soldered on. When the resistor heats up, remove it for a few seconds then put it back on till it heats up again. And keep repeating that until it no longer heats up. Then go on to the next cap. In a few minutes you'll have everything discharged.

One time i opened an old dell PSU that was already fried, took the fan out and put the - and + leads directly into an outlet and BOOM! and POP! smelled like fried electronics and killed the fan. it was scary but cool at the same time. It's cool, i lost no money, it was a school psu that was given to me for my experiments. ![]()

switch your rig off and leave it for for around 48 hours..then just flick the switch on the psu on and off quite a few times, that should do it.

well, I am glad I was strapped for time and no one replied by the time I went downstairs, or you wouldda scared me out of it - ha ha. I did what I said but the fan didnt spin at all. So I opened the lid taped off the inside of the lid which was separate from the rest of the unit, and put the lid back on. I'm still here so I guess it all went well

So it's not really safe to open up a PSU after turning it off, and trying to power on with the case switch a few times...?

Hey, I opened the PSU perfectly fine. Didn't really touch anything though. Still, it worked when I put the cover back on and I didn't get hurt, so win-win.
