Hello, I have recently built a new computer, and when I put everything in, the system power cycles. I can't figure out why. I eliminated the fact that the psu is dead because i used it with another pc, all the cables are snugly plugged in, I used standoffs, I cleared CMOS, put only one stick of ram in, put no ram in. Nothing works. I think the motherboard may be DOA but I want to know for sure.
My Build:

Core i5-3570k
Maximus V Formula Z77
H100i
GTX 680
Thermaltake Black Widow 850W PSU

You got LED activity on the board or its dead?

Yes, I get led activity. The ROG Logo and the Red Line light up. The error thingy, however, does not light up.

This may be obvious but are all the power plugs on the motherboard connected to the PSU?

1 x 24-pin EATX Power connector(s)
1 x 8-pin ATX 12V Power connector(s)
1 x 4-pin ATX 12V Power connector(s)

make sure the after market heat sink plate not shorting anything out. also check that the mb i/o shield fingers are not hitting the usb/ethernet ports or shorting out the bottom of the mb.

Nope. I built it outside the case afterwards and it still didn't work

also, it stays on for 4-6 seconds not immediately turning off. Could this be a failure to post?

i would try another power supply. sound like you got s dead one.

The power supply isn't dead, it works fine in other computers

I really don't wanna have to rma, but I need to know in 2 days if I have to RMA the motherboard. I've unplugged everything from the motherboard and put a fan in to see if the fan spins when it turns on, and it does. But then it stops after 6 seconds. It should stay on, even if not everything is plugged in, but it doesn't. I tried two different PSUs and neither worked. It stays on for about 6 seconds and then turns off
