Alright, so I was building my friend's computer and everything went fine until we booted it for the actual boot. During the prebuild it worked perfectly. Once we put it into the case and powered it on, it wouldn't turn. I took it out of the case and retested the prebuild and nothing happened again. I am at a loss. Also, the power light for the GPU works and turns on when i turn the PSU on. This is the entire supply list http://pcpartpicker.com/p/bYfnmG

Try starting the board by shortly touching with a screwdriver the 2 pins on the motherboard corresponding to the case power switch.
If still no go, try testing the power supply: https://www.youtube.com/watch?v=5FWXgQSokF4
See if a fan connected to it does spin.

If you built the system outside of the case and tested it and it powered up fine displaying the bios post screen and information of how much ram was fitted and the type and model name of the cpu plus the clock frequency it was running at.
It can only mean one thing that when the motherboard was placed on the motherboard mounting plate of the case unit.
A stand-off has been left on the mounting plate where it should not be.
Or it is not lined up with a mounting hole of the motherboard.
In other words you have a stand-off that is touching the back side of the motherboard causing a short circuit on the motherboard.
Undo all of the screws that mount. and fix it to the motherboard plate of the case.
Offer the board up taking note of where all of the screw holes are on the motherboard for mounting.
Then look at the motherboard back mounting plate of the case for the stand-off that is either an extra one or has been fitted in the wrong place. causing the short on the back side of the motherboard when mounted to the case.
That is the only thing it will be, if you know all of the required power from the PSU is connected to all of the points of the motherboard where power is required.
The 24 Pin atx power connector block, and the eight Pin E-atx 12v power block on the motherboard.
Plus any 12v Pci-e power connectors required to be connected to a Pci-e graphics card if fitted to the Pci-e card slot of the motherboard.
