I told him the Seasonic X-460 should be more than enough power and most marketing nowadays over exaggerates the amount of power you need. With under volt IVB proc (even without the under volt) + power efficient GTX 680 both running at stock speed, 4 fans, cpu cooler, 1 5400 rpm drive and 1 ssd, and the power the mobo uses I doubt the system will even use over 300 watts at full CPU+GPU load. Just want to confirm with some more people that the x-460 can handle this system no problem with power to spare. Remember this system will be ran at complete stock never overclocked and remember ivy bridge is only 77 watt tdp 18 watt less than sandy bridge and it's known to use less power than sandy bridge, this is evident due to the weaker vrm's on a lot of IVB mobo's due to less power needed.
He wants to get the 500 watt kingwin fanless psu just to be sure but I think the Seasonic 460 is more than enough. Anyone that could weigh in would be appreciated. I also feel that the x-460 is just a higher quality psu and is for sure the best choice for this silent gaming pc
