hello im new here and know a little about computers however I do need help getting my e machines desktop back in working order. sometime back about 8 or9 months ago my pc went out and i was told it was the power supply. the power supply is an atx power supply i guess and well i have put another one in place and now the computer wont turn on and im thinking maybe the power to mother board so i need to maybe see a picture and a walk through of how to place the wires again for sure. any help would be so appreciated thank you in advance oh the computer is an E MACHINES T3882

The understanding (Jeff Levi radio talk show on computers) was that e Machines use proprietary hardware. Cases and power supplies are among them. Im surprised that you were even able to mount the PS in the e Machine's case. You probably are better off finding an eMachine authorized service center and having it repaired there.

All you need to do is pull the power supply out and test it by shorting the green wire to ground its possible its not the power supply, also if it is true that it takes a proprietary emachines power supply you can get them on ebay for cheap.

He, Levi, wasn't quite correct on the whole. The emachine power supplies aren't really proprietary. I've replaced numerous ps's in old and newer emachines with stock ATX power supplies and have never had a problem. What is proprietary is the front panel connector---the pin out on the mb and the connector from the case are completely different that what is found on "standard" motherboards.

One point....look at the power supply's label and ensure that the ps doesn't need to have a small load placed on it. You can figure this out if the ps's label, where it lists the voltages and load ratings for the ps, has listed a minimum amperage for the ps. Not uncommon for older style ps's to have that requirement, so if you try the jumper trick on one of them, it won't turn on even if it's perfectly fine.

If it does list a minimum load, plug in a fan or two before trying to turn the ps on. It's also an easy, quick way to see if the ps is turning on...
