Powersupply is not sending power

[Squidguy67]

My power supply was working before it was plugged into the computer but now nothing is powered when the psu is activated not even the psu fan. PLS Help!

Go back a few steps here, how do you know the power supply was working before you installed it?

Did you check to make sure everything is plugged in right, case power button wired to motherboard, power supply good enough to power the system, etc...? Have someone else check over the system that knows how to build computer to make sure you did not miss something.
