this was in my brothers computer, he said he heard a pop sound, followed by smoke and a bad smell..
he found a burnt transistor on his motherboard.
not sure which part was the cause or effect, psu, or motherboard.
so he gave it to me because i have recapped a number of powersupplies in the past and he didnt want to risk loosing another motherboard.
none of the caps appear to be bad, i see no buldging.
i think i am going to have to unsolder some wires to get the main board out so i can give it a good inspection for bad parts.
when its plugged into a outlet it gives off a faint squeel sound. this is without any computer connected.
i havent tried it with a motherboard for fear of killing it.
if i jump the green power connection pin to ground, the fan starts up.
with my multimeter im getting the correct voltages.
12+ 12.1v
5+ 5.1v
3.3+ 3.3v
12- -12v blue
5+ 5v purple
? 5+ grey
this psu doesn't have a white wire for -5v
should i just go ahead and try this motheboard on a older computer? or is there a better way to approach this?
