And when I build my new rig when I get home from Afghanistan it will handle anything I throw at it. With l all the extra wc, fans and stuff you want the expandability will be great and it being modular will really come in handy.
The 550W SeaSonic G Series is a much better PSU both internally, and externally. Internally, it has superior components (it is a high-end, very well-built power supply). Externally, it's modular and it even has two 6+2 PCI-E connectors. It has all the power he would ever need, and it has a great price.
I'm not trying to be competitive, just informative.
