NZXT Phantom build trouble

Hi Guys,

I'm building a new rig with the following parts:
NZXT Phantom full tower
ASUS P8Z77-V motherboard
Intel Core i7 3770k processor
NZXT Hale82 850W PSU
Palit NVIDIA GeForce GTX 670

I have fit everything except the graphics card (fitted HD and DVD writer) and when I turn on the PSU I get a green standby LED on the motherboard - all great so far.

But when I push the power ON button I get nothing more - no more lights, no fans, the PSU doesn't start up - nothing. I followed the ASUS installation guide I got with the manual to the letter but it just won't switch on. I don't know if it is a PSU problem, motherboard or just a problem with the ON switch...

Can anyone help or offer any advice at all?

Thanks in advance

Are both the 1 x 24-pin EATX Power connector(s) and the 1 x 8-pin ATX 12V Power connector(s) securely connected to the MB (sorry but have to ask this) if these are ok see my canned speech below;

Best couple of suggestions I can make would be first remove the MB and do a barebones set-up on a piece of cardboard (make sure it is larger than the MB) only connect the PSU, the GFX card, 1 stick of Ram and the keyboard.
IF your MB doesn`t have a power test switch you will then need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else, the idea is to see if we can get a BIOS screen if you do you can then add one component at a time until you find the problem component, you must power down and remove the power cord from the wall before adding a component, second suggestion try a known working PSU, it is not unknown for new components to be bad.
Other things worth checking include, if you used stand offs beneath the MB are they in the correct locations (only where there is a screw hole in the MB) otherwise the MB will short out, check for stray screws or bared wires for the same reason, make sure the jumper cap that can be used for clearing the CMOS is not missing or on the wrong pins

Hi, I have the same case.

Have you connected up all the cables that came with the case? I would start off by checking all the case wiring before doing a a barebone setup.

If you need pictures/descriptions of the cable just let me know :) If you've connected the power button correctly, and the PSU is working, the light above the power button should light up when you press it.
