Quote - 600 on the psu?

 

For the ATI HD 5670 a 400W power supply is recommended or 475W if running CrossfireX in Dual mode).

With 2 Hard Drives / DDR3 Ram / DVD Burner and possibly overclocking this sucker, I need the extra Juice.

I actually went concervative, its not uncommon for people to build systems with a 1200W Powersupply.

The Graphics cards these days and the GPU power is like having a 2nd computer inside your Computer.

I'm hoping the extra GPU will come in handy when transcoding or encoding video.
