Under powered Asus Motherboard (M5A97 R2.0)?

I built a computer back in April to have a decent machine to play games, videos, and surf. Since I built it, I am having issues with the motherboard SATA ports (at least that is what I believe) and the power. Let me start with the basics: putting together my system had no real issues until it got inside the cabinet after I hooked up the SATA components. If i just nudge the desktop slightly (on the carpet), it will trigger the start up, begin bringing the components online then shut down completely without being able to use the power button. The only way I got the computer running is by jiggling the SATA cables (which I have replaced all of them so it is not that). If I shut down from the OS, sometimes it boots up fine and others it goes to the boot menu, which means something got loose and reconnected making the computer think that there is a new component.

Asus, for starters, is terrible at costumer service and told me to again disassemble it and get a new power supply. If I can just nudge the computer and physically get it to change what its doing, does this even make sense?

I am running approximately 368W-379W on a corsair 430W bronze PSU. This should be sufficient to run the system. If it is only running with 90% efficiency, it still has 387W of power.

My question is this, is Asus right that a physical thing like jiggling a cable that seems to be shorting out can be solved by increasing the power supply? Or does this sound more like a function of faulty SATA ports shorting out (hence the starting of the system without using the power button)? Please help! Asus is worthless.

Thanks, Folks!

Huh? If you are really drawing around 370W from a 430W PSU, you are about to start begging for trouble since most mid-range PSUs are not really designed to run at ~90% load for extended periods of time.

If nudging your computer case causes the PC to reboot, you either have a loose connection or a short somewhere. If jiggling something on the motherboard causes the shutdown/reboot, one possibility would be that you have a misplaced motherboard stud on your motherboard tray and it is shorting against something when the motherboard moves or possibly a rear IO shield grounding finger stuck in one of the IO ports shorting it out.

Take it apart, triple-check everything, put it back together and test again.
