New build that doesn't POST and turns back off

[SphereUK]

Build is as follows -

Intel Core i5-4670K 3.40GHz (Haswell) Socket LGA1150 Processor

Gigabyte Z87X-UD3H Intel Z87 (Socket 1150) DDR3 ATX Motherboard - http://imageshack.us/a/img195/9513/z87xud3h.jpg

EVGA SuperNova NEX 650W '80 Plus Gold' Modular Power Supply

HIS HD 7950 IceQ BOOST 3072MB GDDR5 PCI-Express Graphics Card

TeamGroup Elite 8GB (2x4GB) DDR3 PC3-12800C11 1600MHz Dual Channel



As the title states, I press the onboard power button on my Motherboard, it flashes on for a split second then goes off, as shown in this video. http://www.youtube.com/watch?v=n0env8q1mnk

I can take any photos/videos to show anything and will answer any questions.

I am sure it isn't a PSU problem as I am using the PSU with another system now.

I RMA'd the Mobo and CPU to be sure they weren't faulty and they've sent them back saying theyre fine. Any help would be much appreciated! Thanks

Take out both RAM Modules and try one at a time, in different slots too. Let me know the outcome.

Stupid question, but did you try it with a video port plugged in? In that video there's no graphics card or anything plugged into the back of the motherboard.

Also, do you get any BIOS beeps when booting?

@woodysan Same thing with single RAM modules in each slot, Power comes on for 0.1 seconds then flips off.

@houldendub Yeah tried with a GFX card. No beeps, there wouldnt be any time for any anyhow seeing as power only comes on for 0.1 seconds 🙁

Ahh I see (sorry, gotta ask!).

There's that little debug light right beside the motherboard power plug, I know it only shows up veeerrrrrry briefly, but any chance of finding out what it shows? You can usually refer that error message to a figure within your motherboard's manual.

P.S. I know you said that the PSU was used on a different system, is it possible at all to try it out on that old system again?

I managed to snap a picture of what the Debug LED shows, I cant match it to anything in the manual 🙁

Doesnt even look like a number to be honest.

The PSU works in my old system as thats what Im typing on now, I just swap the cables over when I want to try something on the new Mobo
