would i be able to fix my powersupply? i think whats wrong with it is that the 12v lead to the motherboard is 10.9 and thats why its not firing up(just starts and dies after a split second. is there a way to fix this problem? more information on my other thread a little ways down this forum. thanx http://computing.net/hardware/wwwboard/forum/38586.html Asus A7N8X-X AMD XP 3200+ Corsair PC3200 1024 Geforce 6800 OC Thermaltake 480W

if you're only getting 10.9v from the +12v rail, you need to replace the PSU ASUS A7N8X-X Athlon XP 1800+ 8.5 x 200MHz 1024MB PC3200 2.5-3-3-7 Asus A9550GE/TD 128MB WinME/WinXP Pro SP2

Depends where you are getting the voltage readings from. Could be defective voltage regulator(s) on the motherboard. 98% of the population is asleep. The other 2% are staring around in complete amazement, abject terror, or both.

Not all power supplies will supply proper regulated voltage WITHOUT A LOAD, so if you are measuring the output with the motherboard unhooked, it may not be accurate. Best way is to swap components UNTIL AT LEAST you get a working combo, and THEN check the voltage UNDER LOAD

alright so listen to this. i take the PSU, and put it by the window sill for a couple hours and it gets really cold. i plug it in the computer and it runs it, i shut it off and try this two more times. then i shut it off and try it 5 minutes later. it doesnt run. what is going on here. i put it back on the sill and then installed the psu into the comp and then tryed it out and it didnt work. wat is going on here?

There could be a lot of things wrong... cracked pc board, dried capacitor, Bad or overheating voltage reg, lose connector... the list goes on. It's clear that there is an electronic fault and what you have to do is take a dmm (voltmeter) and work the problem backwards. If the voltages on the other lines are good (+5 and -5 volts) then the primary switching power supply is okay and you should narrow your search to the +12v reg section. With a voltage but low I would first supect a capacitor problem (dry, leaking or loose). From this point on, you either know what you are doing, or you don't...
