Yes, if you have a brand new GPU, say a 7800GTX...nVidia clone or branded...you need a 600W+ power supply or else your system will be drained. Even
though 500W is OK, all of your other hardware and trinkets you might have will drain that power and as soon as your GPU needs more power to pump out
massive graphics, it will shut your system down...like when you blow a fuse or trip a breaker.
