HELP HELP HELP!

I recently purchased an Antec SX1030B (as mentioned in earlier posts) I have had a big big problem and I'm not sure what to do.

The Antec 300w power suply has been giving me problems. At first I thought it was just the power supply that came with the case because when I plugged in my old PSU into the antec case everything worked fine. So I returned the Antec PSU for a new one in hopes of solving the problem. However I tried thenew one last night and I still can't get it working.

My motherboard I am unsure of what the exact brand is but I know it is a P3 mobo that supports RDRAM. I am unsure if it is the power suply or possibly the PSU does not support my motherboard.

One thing I noticed is on the Antec PSU power supply it has the standard 20 pin plug, 6 pin plug and a new 4 pin plug (Sorry I don't know what they're called). My old motherboard does not support this new 4 pin plug but according to the Antec manual this PSU should be backwards compatible.

I don't want to go back o the computer store to return the PSU again if really in relaity it doens't support my mobo.

Can anyone hel pme pleaes before I have to trek an hour to the computer store again? =)

Running a PIII with RDRAM those motherboards did run into some problems, you at least need to know the motherboard chipset, I've tracked down some info for you from Intel Corp. regarding the 820 chipset and related problems if thats the chipset you have you can find the chipset number on the chipset itself, which should be the largest chip soldered to the motherboard. If it is an 820 check out www.intel.com/support/motherboards/desktop/vc820/
The site lists requirements such as power supply output voltages, and every required specification, if the power supply does not meet the requirements it will not work. You may be running a different chipset than the 820 but it was the one I tracked down that fit your other parameters. You can also go to www.bootdisk.com in the Utilities section and download a motherboard identifier program that will tell you exactly what motherboard you've got.

Antec power supplies have output ratings that are a little "enthusiastic" at best.
