Please help, im getting no power!

[Millgo47]

I just installed a new power supply CX750
I thought I rehooked everything back the way I had it but when I hit the power switch I get nothing.
My tower is HAF 932 full tower.
My mother board is HP IPISB-CH2 (Chicago)

Not sure if the pictures help.

Do you mean the power switch at the wall socket?

It could be as simple as not having pressed the power switch on the back of the Power Supply.

Nope I wish though tried that a few times to be sure.
