I got this older (not too old) ATX power supply that a guy gave me, it's generic I think, but it's giving me grief... I plug it into a mobo and it fires some stuff up and then shuts down... now I know you think it sounds like under powered... but all it's running is a P1 233 and 64MB EDO a 3Gb HDD and a cd rom.... oh, and a vid card (generic mach64 or something). so I unplugged the thing out of the system and put a pin from the green wire to a ground wire (to start it without the mobo) and I hooked up one 120mm fan to it.... the PS spins the fan up for about 1/2 a sec, and then dies, now if I keep pulling the pin in and outt of the ATX connector I can spin the faan constantly... but as fun as that is... I would like to fix this thing I could use it in this P1 system for my mom's solitaire system (don't ask)
