Z77X-D3H No power at all

[sablek]

Hi,

Received my new Z77X-D3H rev 1.1 today, along with new CPU (i5-3570K) and RAM (Crucial Ballistix BLS2C8G3D18ADS3CEU Sport XT 16GB (8GBx 2)

I have a EVGA 660ti 3gb and a 650w PSU.

There is no power whatsoever going to the PC when I hit the power switch.  I have checked that both power connectors are seated correctly and that the front panel power switch is connected to the red F-Panel on the motherboard.

I suspect it is the mobo because there is zero power going to to PC.  The PSU was working perfectly well with the older motherboard a GA-P55-USB3.

What else can I check to get this up and running.

Thanks

Have you taken the front wires off and use a small screw driver to try it on those two pins.

Do you mean short them?

I tried the psu against the original mobo after posting my original post and it fired up straight away so quite sure it isn't the psu.

I removed the new ram from the mobo and tried again but nothing.

Would an incorrectly positioned cpu stop any format of power going through or would it just fail post?   Is there any mobo grounding I am missing which could stop it?

Thanks for the reply!

Also, would removing the CMOS battery for 5-10 mins for drain make any difference in this instance?

Many thanks,

Take the board back out of the case and try it on the box it came in. That way the board has nothing to short out on.

A board will boot no matter what you have installed. I just tried it with nothing but a CPU fan connected. It boot but shut right back down.

Ok so now when I plug it in and hit the switch, the psu fan and light on coolermaster seidon comes on for 1 second and then everything goes off again...

Do you have the cooler master plug into the CPU fan power header.

I just tried it with nothing but a CPU fan connected. It will boot but it shut right back down. 

I'm just asking I hope you are not trying it this way. I was only making a statement that the board will still boot without any thing install.

If you do have everything installed CPU, Memory & Video card. Than it sounds like you might not be getting power to the CPU.
