need help

post #1 of 5
Thread Starter 
i just bought the seasonic 750 power supply so i can run a sli setup with 2 gtx460. usually my buddy handles all my changes because i literally know nothing about computers.. since i have bronchitis i would never ask him to come over and ask to redo so i attempted to do it all on my own. i plugged the power supply into both 460 graphic cards the big slot into the motherboard a 4 prong adapter into the cpu. i then hooked up my cdrom drive and my main drive on the same cable and also my storage drive with another cable.

i did everything my buddy told me to do and no power to the computer at all. am i missing plugging components in or anything? (i apologize in advance for the wording on everything im not great with computer components)

You possibly forgot to hook something up.

Maybe the rocker on the back of the PSU is on the OFF position.

Maybe your power button isn't connected correctly.

Maybe you, in your not knowing what you were doing, toasted your motherboard video card or CPU and cost hundreds of dollars in damage due to static electricity.

Good luck

If you still cannot power up my seasonic 520 owners manual suggests toggling the PSU power switch on and off a few times with five second intervals my seasonic is great
