Is this a sign of a dead PSU?

post #1 of 11
Thread Starter 
My parents' computer suddenly shut off the other day. After resetting the cables and what not, the computer does nothing when I hit the power button; no lights nor any signs of life.

Is this the classic symptom of a bad PSU?

Yeh thats the most likely problem

Easy way to test it to remove the psu from the system unplug everything then with it switched off get a paperclip and put it into the green wire and into a black wire then plug it back in and when you flip the switch on the back if it starts up the psu is fine and if it doesn't its dead

There are plenty of black wires, the green one and any black will do?

I did it with another working PSU in the house and the fan started up. This was using any of the black lines.

After doing it with the suspected dead psu, nothing after using all the black wires. I guess it's dead?

Bummer.

Well, if anyone cares, there is a Corsair CX430 for 20USD (or 17USD if shipping outside of California) on newegg. (After MIR and site discount)

I picked up one for myself smile.gif
