the PSU would be fairly easy to test. Just remove the ATX connector and use a jumper wire (i usually use a paper clip) and jump the green wire on the connector to any one of the black ground wires. Turn it on and see if the fan spins. You can also add some devices to the 4pin molex connectors to give it some load.

Although its still possible that you may have a bad PSU if that works, its not likely. Other things to check would be to make sure the power switch on the back of the PSU is in the on position. Be sure that the wires from the front panel are all going to the correct places. Be sure that the fan for the HSF is plugged into the correct fan header. Many motherboards won't power up if they don't detect a fan on the CPU fan header.

If all those fail, you can try to disconnect the front USB ports. I've had one board that would not power up if the "shield" wire going to the front USBs was connected. I doubt thats your problem as i've build dozens and dozens of boxes and i've only had this problem with one model and thats the EPoX 8RDA+. Great boards though.
