Power Sparked when plugged back in?

cjenkins08 · 10-31-2009, 09:52 AM

I took an old computer apart, just to reassemble it and after removing all the components and hooking them back up, I plugged the computer back in and it sparked at the power supply. I am not to concerned about the computer, because I am sure the PSU is fried, and I never user it but what could of caused this? Would it be the wires plugged into the wrong components, or could it be Electrostatic Discharge from when I was taken it apart?

Also what do the numbers represent on the power supply wires P4 P5 P6 ect..

Thanks in advance.

Most likely the PSU just expired. Low quality PSU's tend to take other hardware (Mobo/CPU) with them but quality PSU's usually don't.

I could go for that but the computer worked just fine, before I decided to take it apart.

Any hardware can fail at any time although there is a possibility you you contributed to it's failure.
Brand & Model of the PSU?
Did you inadvertently move the 120/240V switch on the rear to the improper setting?
How far did you disassemble the PC? Did you remove the Mobo?

PSU Brand -Bestec, Model- Atx100-5
No the switch was still at 115v.
I took the whole PC apart, motherboard and all and then put everything back together.
