Replacing Dell Dimension 9100 Powersupply with an Antec 500w

CrimsonxX · 10-21-2008, 02:49 PM

Im actually having the same exact problem on my Dell Dimension 9100. I just picked up an Antec 550w, replaced all cords accordingly and now when I turn it on everything seems to start up such as fans, ect. for about 3 sec and then it shuts off except for the green mobo light. Could the brand not be compatible or did it fry something maybe?

Same problem as what?
What was your original problem?
Does your old supply have a 6 pin connector like this connected?

Sorry about the confusion, my post was moved. The problem is that I replaced my stock psu with a Antec 550w psu. Safely unplugged the old one and plugged everything in correctly (99.9% positive) It had a 4 pin connector going to the cpu and 24 to the mobo.

When turned on the fan on my videocard spins and the usual sounds during start up but then completely stops after about 3 seconds. If any other info is needed let me know. Thanks a lot.

Question is what if anything did connector P4 hook to?
Is the problem listed above your original problem if not what was?
Which diagnostic lights are light up on the front?

P4 was not hooked up at all. Yes it was the original problem. There are no diagnostic lights in the front when powered on. I just checked out the reviews on newegg and it seesm like this psu has some serious compatibility issues and a lot of DOAs. I'm just gonna pack it back up and return it and pick up a different model/brand. Thanks for the help.
