WHAT!_ "Power Supply: I would suggest at least a 500 watt power supply because of the graphics card i am about to suggest, 650 watt would be best."
A machine with Intel Core i7-3770K and GTX 690 consumes 450W maximum and this graphics card is for cracks only (dual GPU monster. The same machine using a GTX 680 uses less than 300W and with a 7979 GHZ Edition 350W. So please don't tell the guys that they do need new and stronger power supplies ;-)
Here's something to consider:
CPU: 75W
GPU: 118W
RAM: neglible
Sound Card: 15w
Now that doesn't SOUND like a whole lot of watts. But what about AMPs_
CPU: 5.5-6amps
RAM: Neglible
GPU: 50(GTX 650) to 72(GTX680)
Sound card: 5
So then if you have a 350W PSU that can only push out 40 amps to the 12v rail, you can't use your GPU fully. You will lose frames(Granted it might still be livable, but you still lose em). Of course a 550W PSU is cheap enough, and if the right brand should supply enough AMPs.
