    Default No Power GA-EP45-UD3P

    I connected my Corsair 650TX to my GA-EP45-UD3P using the 8 pin (2x4pin)12v power and the one 24 pin ATX board power connector. I have absolutely no power, the PSU fan doesn't spin ... Absolutely nothing. When I test PSU using Corsairs troubleshooting (paperclip test), the fan spins up as expected. I pulled everything out except for the CPU (Intel E8500) and still nothing. I just started building this so it's never actually worked .... Any guesses or suggstions on how to troubleshoot?

    When I've had this behavior in the past it's ALWAYS been caused by the motherboard being shorted to the case somehow. Try removing it from the case and starting it on that foam piece from inside the box. If it works, you now know what's up.

    Suggestions for where the short may be occurring:

    Most likely it'll be that you have an extra standoff screwed in somewhere it shouldn't be. It's possible (although not likely) the screws into the standoffs are causing the short. If your case came with little red washers (or maybe that was the motherboard? I know I got some in one) put those on top of the board before screwing in the screw.

    Hope this helps.

    Another thought:

    You can always use that black electrical tape to cover the standoffs under the board. Then just screw the screw through the tape into the standoff.

    I actually had to do that once, but that was years and years ago.

    Good advice above ^^^^^

    1) It might be as simple as a faulty on/off switch.
    2) You might have incorrectly hooked up the on/off switch to the front panel header.
    3) You might have accidentally mixed up the wires from the RESET switch with the ON/OFF switch.

    If necessary, carefully (momentarily) connect the two jumper pins [PW+ and PW-] together using a small flat blade screwdriver or a spare jumper connector from a hard drive or cd/dvd drive.

    It's always best to build and test your mobo outside of the computer case. I take it one step further and install all software and run stability tests before I mount the mobo in the case.

    I luv the "slotted screw driver" trick. ;) Time and time again it has saved me the hassle of downloading a manual and looking up the proper hook it up order.
