Everyone probably heard this a hundred times so I'll list my specs them my problems:

Corsair CMZ8GX3M2A1600C9 Vengeance 8GB (2x4GB) DDR3 1600 Mhz CL9 XMP

Sapphire AMD Radeon HD 7950 Graphics Card

MSI Z87-GD65-GAMING ATX Motherboard

WD 1TB 3.5 inch Internal Hard Drive

RM850 CORSAIR PSU

CiT Vantage Midi Mesh Gaming Case

Intel Core i7 4770K Quad Core Retail CPU

Using the fan included with the CPU boxing

The problem is that my PC wont turn on, the power is definitely working because when i turn the back switch of the PSU on a green light comes on my motherboard, when i go to the casing to turn the PC on, nothing happens, everything is correctly wired up, I haven't done a benchmark check yet but is this necessary as the motherboard isnt touching the case as a green light is coming up on the mother board?

I had this exact same issue in the past.

For me it was caused by a dodgy PSU (Power supply) This was also a Corsair PSU, a HX650 if memory serves and was brand new. Sometimes even the best of branded products can turn out to be duds and be DOA.

This would be the first thing I try to eliminate/prove.

If you can; use an alternate PSU, perhaps from your previous machine? (if you have one) and try it then. I personally would make this my first step

The check list provided by snowctrl is an excellent resource. With this nature of problem, I would do the PSU replacement/test I suggested first however but that is my personal opinion.

Remove the power button lead off the motherboard and short the power pins (refer to maual if unsure) will it boot then? could be a faulty switch or loose wire on the front panel (if its all wires correctly). If it wont boot then, make sure the CPU is seated correctly and none of the pins have been bent when installed.
