Diablotek DA Series PSDA600 600W ATX12V v2.2 Power Supply

Every thing is hooked up according to what the mother board says. But when I press the power button there is no response the power supply did in fact make all the fans twitch. But that was only once. I am worried that the problem is within the front panel but I am not 100% sure. Please help. Also everything's new. Will install windows 7 Ult when it actually turns on but at this point its not even powering on

This might sound stupid...but did you connect the pci express connectors to your gpus?
I'm assuming you did, but I want to double check.

Check for a short somewhere. Could be shorting anywhere in the case, the motherboard standoffs, fan wires, etc.
