built system but it does nothing when booted

[UCBPhantom]

I just built a system with the following specs:

Gigabyte GA-7DX mobo with Athlon XP 2000+.
512 MB (2x256) DDR PC2100 ECC, Registered RAM
PS: Enermax 365P-VE 350W

the rest is pretty much irrelevant to the question.

I press the power button, and nothing happens. None of the fans starts spinning, the only thing I see is a little yellow LED lights up on the motherboard. It's labeled DIMM CONN LED and the manual only says that it's on if there is enough power for the RAM. I have checked all connections (fans, power supply, etc etc etc) *many* times, reseated the memory, tried using just 1 of the RAM sticks, etc. Nothing seems to help. The parts are brand new (won them in the AMD XPP giveaway in santa clara). RAM was bought a few months ago but has never been used.

Please help! I'm freaking out here...would really like to get this thing up and running. Any advice highly appreciated. Thanks.

You may have a bad power supply, but make sure that you have the power switch connector connected properly. My roommate did that about 6 hours ago and couldn't figure out why nothing was coming on.

i plugged in another power supply and it worked. i bought this PSU from openlinx.com and apparently they are rated *very poorly* for returns. Do you think there's a chance I can call my credit company (Visa) and complain? Is there some sort of protection, if they start wanting to charge me things for sending a replacement?

Thanks,
