PC booted fine till monitor plugged in.

[Someretardedguy]

Built my first PC. I booted a couple of times without the monitor because it didn't come in yet. All those went fine and the computer stayed on for at least 5 minutes in one of the tests. I got the monitor in and booted with it and the first time was good.

Then I plugged my windows 10 USB to install Windows and I didn't even get past the welcome screen before my PC shutoff. No LEDs, fans etc.

Things I tried:
Remove CMOS battery
Tried different power cable
Took out/reseated RAM, cpu cooler, GPU.
Rechecked all the wiring made sure nothing was loose
Rechecked my front panel wiring
Reset the mobo thru shorting it (or at least I think I did).
Took out all the wiring from PSU and reconnected them.

Possible causes:
My installation of the mobo wasn't the best ever. Might have fucked it up

Same with the cpu cooler. Not the smoothest installation.

Specs:
I5-6600k
Cryorig H7
MSI z170A sli
Gskill 16gb DDR4
Evo 850 500gb SSD
Asus dual gtx 1070
Nzxt s340
Evga G2 650w

This is sort of a last ditch attempt before I start RMAing stuff left and right.

Did you insert the drive in an USB port, and not different one?
It seems that it created a short, or something.
Try testing the power supply: https://www.youtube.com/watch?v=5FWXgQSokF4
See if a fan connected to it does spin.

Yeah it was just a USB port on the front.

I'll test out the power supply when I get home and let you know.

Check also if the front USB port is plugged in the correct header on the motherboard (check the board's manual).

For the paper clip test, my psu doesn't come colored wires. Here it is: http://imgur.com/p5WvZP8
Where should I put the paper clip?
Also I don't have a paper clip (yeah I fuckin know) but any 2 metal pins should work right?

Wellll I just realized that one of the pins on the USB connectors is bent and broken on the mobo. So is that pretty much it, I have to RMA the mobo?

Probably yes.
