Why won't my pc turn on

[Mathew97]

This is my first pc build. I'm using the i5 2500k stock cooler, 8gb corsair vengeance ram, asrock z75 pro and a coz 750w zs series. I might have done something wrong since this is my first but I don't think so.

When I plug everything in (yes I plugged it in correctly on the power supply and outlet ((I know the outlet works)) and flipped the switch) but there is no sign whatsoever of power.

Nothing lights up, nothing beeps no fans spin, absolutely nothing which leads me to believe it is a faulty power supply. What do you guys think?.

Also I got the power supply from tiger direct are the good with replacements?

check that the 4/8 pin atx power connector is plugged in. also check your case header cables. all it take it to put them on wrong or backwards for no post. also check that you used the mb standoff so your not shorting the mb to the case.
