is my PSU safe for use?

post #1 of 7
Thread Starter 
Hi, I have a corsair 750w PSU ( non-modular)

a couple of weeks ago, I was trying to connect a fan to it and when I turned my PC on, I saw a small spark come from the back. I assume it was because I was trying to jam the connectors together..

the PC will power on, but nothing comes up on my display screen.. now before this incident occurred I had my processor running without a fan on for like 2 days, so Im hoping a damaged processor is my problem and not the PSU..

Id like to know if it would be ok to use it for another build

thanks

A spark from the back of the power supply, or the connector?



It sounds like you did quite a few, to be honest, stupid things with your computer. Why were you running your CPU without a fan? Why were you plugging in fans while the PSU was on?


It might possibly be that the PSU, the motherboard, your graphics card, or you CPU could be dead. Only way to find out is to swap parts out for known good ones and see what resolves the issue.

Yea the CPU thing was dumb. I read somewhere e8400s didn't require a fan, so I didn't care when mine stopped working (was really lazy that night).

Everything was turned off when I plugged in my fans. I don't know if its just me but those ****ty plastic fan connectors are a pain to plug into a power supply. One of the rods from the fans connector got pushed back and I tried to push it back up and do my best to plug it into my psu, but I sort of just forced it in and Im 100% sure that's what caused the spark

I saw the spark near the connector and the PC turns on fine, so I don't think there was any damage to the PSU. Im just wondering if its still safe to use and if there is anything I should look out for as im going to use it for another build

thanks

The PSU should be fine, I believe. Your CPU and motherboard, though, I'm not sure tongue.gif

turned out it was the CPU. SO happy, it could've been a lot worse

Glad to hear it wasn't worse. From now on, use heatsinks on parts designed to need heatsinks. wink.gif
