Solved: Power Supply versus Motherboard

This question is regarding the power supply for a custom built computer. Tested old PS (starlogic 300 watt atx) & it was dead according to ATX power tester. So I purchased another power supply (closest I could find --Vio power w/atx 12V 420w max) that tests fine using ATX power tester. I connect it to the mobo and turn on.
The only response is a red light on the mobo.

Both p/s are atx that plugs into 12V socket.

I find the following on the mobo for mfr: ASUS ASB100/SIS963/ATA 133. Not sure where the product ID is on this mobo so wasn't sure what ps would be compatible.

What should be my next step for testing?

 

A standard ATX power supply like the one you bought should no problem running that motherboard. The motherboard may well be fried or shorted to the case.

 

Is there anyway I can verify this? And, would symptoms be the same if the cpu were fried and the mobo okay?

 

I see you have crossposted the same problem over at least two different threads. Please don't do this in the future. The dead CPU could also give you the same symptoms you are experiencing now. I think the red LED is for the AGP slot telling you your video card is incompatible.

 

Sorry 'bout the crossposting but figured maybe I needed to reword it correctly and couldn't figure out how to delete it. Thanks for the information, it helped me resolve.
