repair broken psu

[l3ored]

i have an old atx psu that has finally "died" today. it's 12v line reads at 10v when i jump it to turn it on, and its not enough to power a computer. any ideas how to fix it? i have nothing better to do right now...

If you aren't expierienced with electronics, a power supply is the last thing you should be working on..its not safe if you don't know what you are doing..

ya, you wouldnt want to fry the rest of your computer- your best option is probably just getting a new PSU

I wouldn't. I'm saying that as a person who has shocked himself with a PSU.

Since you live in Hawaii, I'd just get some Salvia Divinorum, and smoke away. When you wake up you'll have repaired your PSU. 😛

Actually I'd reccomend that you buy another.

I was amazed, tonight I turned off my multimedia speakers (with integrated amp) attached to my PC, took them out to the car, and hooked them up. (They are actually my make-shift car CD-player speakers.) While hooking them up, I turned them on, and heard the noise and watched the green power LED light up ... and then I realized that I hadn't even plugged in the auto inverter yet! Wow, the caps in the audio amp must store a good bit of juice..

So, by way of a similar example, yes, I suppose that in some PSUs (that lack bleeder/load resistors), they will store a charge in their larger caps for quite some time. Be careful.
