Did I screw up my PSU?

post #1 of 11
Thread Starter 
Was adjusting a fan connector on the PSU[2 pin I believe] using a screw driver. I forgot the PC was on and it looked like I completed some circuit when I touched the screwdriver to both pins because sparks flew out. The connector still works fine. Could this "surge" have somehow damaged the mobo/cpu/psu?

Yikes! I'm no expert but I'd say if anything is damaged it would be the PSU most likely. I'd keep an eye on it for sure.

Since it was just the fan circuit in the PSU, I'm going to go ahead and say no.
The PSU may have failed to handle the surge, though, and it could be damaged. There's also a chance that the motherboard was hurt, but you won't know until you test it.

youll have to test and see, its the only way to tell. At least boot, then stress test.

In the future, you should probably not jab screwdrivers into a psu.

Looks like you shorted the connection, most modern PSUs usually have protection against this sort of problem, and will sometimes shut off.

I once managed to hook up a 5V laptop fan to the 12V wire by accident, it was just like a Catherine wheel... lots of sparks from the fan, but the PSU was fine.

Hope that helps.

The fan connector still works fine. How can I test it? Stress with prime95?

Still boots fine. I don't think the PC turned off at all.

Most likely OCP (Over Current Protection) would have kicked in and limited the current to prevent any damage to the wiring. Common in lab power supplies and now the technology has been in PC PSU's for the last few years. Do a prime test if it makes you feel happier, but if everything is running as normal, should be fine.
