Hey guys, I'm having some trouble getting my new build to boot. When pressing the power button, I hear a 'click' from the PSU and nothing beyond that. The fans begin to spin for a quarter second and that's it. The 'Start' and 'Reset' buttons are the only lights lit on the board.

Components:
Asus Maximus VI Extreme
Intel i7 4770k
32 GB G.Skill Ripjaw X DDR3 2134
512 Samsung 840 SSD
3 TB 7,200 RPM Seagate HDD
Nvidia GeForce GTX 770
Corsair HX 850W PSU

I get no signal on my monitors and the board does not POST. There is no Q code displayed on the board.

I have tested the power supply with a tester and have tried booting with a different power supply (different wattage, same brand). Same click. I have replaced the motherboard and am experiencing the same result.

I have triple checked my standoffs and cables. I attempted a bench start using both the on board power button and by shorting the board. Same click from PSU.

Is there some sort of compatibility issue with Corsair HX series PSUs and Asus Maximus VI boards? I called Asus support and their answer was to RMA it (which I did, with the first board this happened on).

I have no idea where to go from here; any help would be GREATLY appreciated.

Hello, thank you VERY much for your suggestions. You helped me think outside of the box a bit. It turned out to be the mPCIe wireless card. Once I removed it my machine posted and I was able to get into BIOS! Thank you for your help.

Are you sure nothing could be creating a short on either side of the motherboard? The smallest conductive material could be the cause of a short, like a stray staple or tiny piece of loose copper wire.

This is a photo that shows the START button on the board is backlit by an LED. On my board, that backlight is illuminated once the PSU is switched from OFF to ON. Is this true for your board? Does the LED turn on when the system is OFF but the PSU is ON and ready to supply the board?

Do you have an exterior power button connected to the motherboard connected to the case or something?

You'll likely need to have Asus issue an RMA for an in-warranty diagnosis, repair or replacement. Could be a bad trace or fuse or any number of things.

I can't find anything that would be causing a short, the only thing I could think of that could possibly cause an issue is the heat sink backplate, but the contact points are covered in some sort of insulation. Nothing else was touching the first board when it was benched and I still got the clicks.

Yes, you are correct about the LEDs. They are on when the PSU is on. And yes, I do have an external power button connected. But I did try to start it with the onboard 'start' button and by shorting the pins.

I would agree with you about RMAing, but this is the second board that I've gotten the same exact results with.

I don't know if this matters, but after the PSU clicks initially, it does not click again when I press the button until I power it off and back on. It only reacts to the first attempt at powering on.

Are you using the power cables that were included with a PSU and are they in tact?

Did you depress the START button while the external power switch harness was unplugged from the mobo? How about ONLY having the 20+4/24 pin mobo power, 8-pin CPU power, the CPU and one stick of RAM inserted, alternating slots? You removed the mobo from the case or whatever you have and tried all this on a table, desk, bench, etc. right? You can try removing the heatsink from the CPU and seeing if it'll post.

And are you positive that the RAM and CPU are not defective and functional, also properly seated? And of course the power cables are fully inserted.

You've probably tried a lot of methods and I'm only trying to help you troubleshoot.
