Hi.
Today i got my MB (7700k+16gb 3200cl g.skill+nh-d15).
Connected everything and no signal when I press power button.
I took everything from chasie and tried to put only CPU+MB (no memory,gpu etc)
When I turn on my PSU (switch) there is no light at MB (should there be any) when I try to turn on PC , nothing happens, no can spin in PSU. No light at MB (ez debug led)

Here is how it look when I just turn power button on my PSU.
Without CPU is the same, no signal at all (I should get error that there is no CPU)
Any ideas? Tried with two different PSU.
Sorry for my English, it's not my native language.

Unless there's a wiring problem with the power button involved, there may be an issue with the CPU cooling fan. If there's no fan connected to the CPU fan header, then the system would consider CPU preservation as more important than continuing to boot without proper CPU cooling. Also: double-check for stray screws or other metallic items that may be short-circuiting the motherboard.

I checked it outside case. With or without fan is the same. No boot, no signal, nothing at all. Looks like mobo was dead already -_-

Carefully short the two power switch pins on the mobo to see if the board fires up?

You can also short the green wire from the PS to any black wire to see if the PS starts up, but if you've already swapped out the PS then...

This is only way to turn on this mobo because there is no power button on it.I short power pins to boot but no go.
I already RMA it but what a luck to get new one that is already dead :/

PS. Is here anyone with this motherboard?

Barebones does not mean what you think it means. Get off of the bag, because antistatic does not mean what you think it means either. Always test with CPU cooler attached and plugged in, ram installed, and a known good quality PSU rated for the new hardware. And turning the psu switch on and off is not the way to go, because F the LED diagnostics. Boot barebones, shorting the pins, try the ram 1 stick at a time, and then pronounce it dead. Leaving it on that bag was bad juju.
