    Thanks for all the help guys, I went to my cousins place and used his power supply, everything worked fine, bios screen showed up, fans started spinning. Tried it with the graphics card on and 2 sticks of ram, everything worked.

    So, conclusion: Power supply was bad, I had the EVGA Supernova 650W 80 Gold Plus, I'll be buying a new power supply and update you guys once again if it works.

    Glad you were able to test with a known good PSU to find that the PSU you got was defective. Best of luck here on with migrating it into computer case and no problems.

        Hi

        On the power supply there is 2* 6 pin connections one for pcie and the other is for the motherboard if you swap those you will get a short on the supply. IE the fault you have, before returning the supply check you are using the correct power supply output .

        *This motherboard has an 8 pin, not a 6 pin that is common with video card 12v power.

        Newegg has good images of this GIGABYTE GA-Z77X-UD5H motherboard.

        I haven't seen yet where a modern design would be implemented that would allow for power to be connected wrong. Everything is keyed in modern PC's that I have ever come across to keep you from an oops smokeshow. Do you have a reference to this happening that we can see online. Just asking because I have never come across a situation like this with 2* 6pin molex being different yet. The only computer cables I have seen plugged in wrong are floppy and IDE cables if they are the older ones without the key pin. The good thing with those is that if its wrong you shut system down and turn the cable end 180 and try again and it didnt destroy anything.

        Not only that but the 6 pin connectors are keyed differently for MBoard and PCI-e...
        Only people i've seen get it wrong were overly aggressive cause it takes a good amount of force to put 3 square ports into round holes.

        See Reply #15 from OP, i.e. bad PSU.

        I too saw it when it was posted. It was the PSU as I initially thought, which was proven on 4/13 when GFroun followed my suggestion to try a different PSU.

         Was just replying to lisa_maree here about the 2* 6pin molex. And fact that this mobo has a 8pin 12v molex connection.
