As far as im aware everything has been placed as it should on first boot it came to bios then after a few minutes cut out by itself. since then i have tried numerous things i have used known working ram instead of my own, removed all drives and graphics card and left to see if the power cut out still occurs it does, there are no out of the ordinary beeps, from the motherboard.
there is thermal paste covering the cpu heatsink interface, a friend of mine is bringing me a power supply checker to check the supply later, its not a thermal cut out as the bios reads very low temp and a i can turn on straight after cut out, i currently have the system on a bench not in case so its not being shorted by the case, im actually lost as what to do next the only thing i can think of is the psu is not compatible or has a faulty wire, the mobo is faulty or the cpu is faulty, and im not sure how to test these.

If any one has any ideas id be greatfull it was a costly build so im pulling my hair out at the moment

PSU checked not PSU

You've got ALL the power connectors in the right places on the motherboard? You have all required power connectors running to Video card (it probably has two)? You aren't exceeding amperage or voltage at the wall socket? PSU is not switched to the wrong voltage (some have manual switches)?

I'm assuming you checked all those, this is just an odd problem so I thought we should eliminate the obvious ones right off the bat.

I'd be inclined to try a different power supply, even though that one passed your tester. You should only need 500-600W to power that rig, so if you can find one to borrow for a test, that would be my next step.

There isnt a manual switch its 1050w power supply asus recomended 700 plus for my configuration all power connectors are in correct place, i removed gaphics card and had just mobo, psu and ram connected and same issue occurs as basic as possible. its baffling me that with just power supply ram and cpu it still switches off, going to try jumping mobo see if its the phantom case.

I don't think it's a wattage issue, I think you have a flaky PSU so I wanted you to try a second one.

I might just try mounting it up in the case. There is some grounding that is supposed to be happening between case and power supply and motherboard and the standoffs on the case.
