My dad and I just finished building a gaming rig,we followed a guide on youtube step by step and just finished it. We plugged in the PSU and the green light on the motherboard turned on for a second and cut of. When I press the power button nothing turns on and we here no fans, including the fan in the PSU. We're almost positive we have the correct wiring and all that. Is there any way to check if your PSU is dead or could it be something else?

Power Supply: Brand New out of the box Corsair TX 650w.
GPU: EVGA Nvidia GTX 760
Case: Antec Three Hundred Two
Motherboard: Asus Z87-A

I don't have the 2/3 pin adapter is there a probe or anything I could buy at somewhere like radioshack to test the PSU?
