After trying the steps mentioned by evil262 and the others in this thread, removing if would have worked if you had mounted something wrong. The only other thing I could've come up with is if the reset button on the HAF had been jammed in a depressed position and you had hooked it up to the mobo. That would have caused the fans on and lights and such without a post. However if your getting nothing, then you can check the voltage out of the CPU 4pin to be sure it's not your PSU (though I doubt it) then likely RMA the mobo =(
Well I go ahead and switch the old PSU in (which I hadn't used in the HAF) and wouldn't ya know it, it worked. POST! Well I'm glad it's not the Mobo, although I have been wanting to get rid of it and get a better board in there. Anyway, does this mean the Corsair PSU is faulty? Should I test the voltage on the pin still? The monitor never got a signal with the Corsair HX750w, but the stock 460w worked just fine. I am a bit lost here.
