hi guys i have a 1000w computer power supply that is ticking even when it is off so its not a fan issue. the ticking seems to be on intervals of 1 second

the power supply was turned on today for the first time in about 5months

does anyone know what would cause a power supply to tick?? and does it matter?

Sounds like a type of overload to me. or a faulty electrolytic shorting out.

Check for bulged capacitors on the board.

It seems to be a non canonical discharging of the big capacitor check it with a ohmometr and replace it. Also check the 11W or 11W resistor ( the white one) if has some continuity problems and also replace it.
but the electrolytic capacitor is more sensitive and I think is the responsible one

hey guys i found what has caused my power supply to tick. it seems that i plugged a 250v 75a into the power supply but all the other cords are 250v 100a

so i tested the 250v 75a cord on an old unused power supply, i checked before hand to see if the test power supply was ticking and it wasnt. after i plugged the 250v 75a into the test power supply sure enough it started ticking.

so i guess the lower amp has damaged somethign inside my power supply causing it to tick??

11W resistor?

I've never seen a 11W resistor, do you mean a 11Ω resistor?

Still how do you know it has a 11R resistor without looking at the schematic?

That's impressive given that the origional poster hasn't even given the model number or manufacturer. :rolleyes:
