OK so I bought a new motherboard (gigabyte z87 ud5) and it won't power on at all. I've tried multiple PSUs and no success. Everything is connected properly but it still won't turn on. I've tried clearing the CMOS and removing the battery without avail.

The only thing I can think of is when I first tried to start it I had a gtx 770 installed and the power leads were not connected in the right modules. Could this be the cause?

Thanks.

BTW it started first attempt but the error message "please plug the correct cables into your graphics card". After that I done something and then no power at all. So it wasok to start.
