670 requires a 500w psu with 30a on the 12v rail...with that said i always recommend more headroom for the future. go 650-700w for sli the future...stick to antec, corsair (non cx series), seasonic brands that are 80+ efficiency.

I'd say a good quality 500W supply is more than enough, but it must be good quailty. If you're looking at SLi for GTX670s then I'd be looking towards a 700W-800W supply.

I'd certainly say to miss Cooler Master as I've had bad experience with them in the past.

I've re-evaluated the options I had to pick from and from the information you guys have given, think ill be going with this one instead:

Antec HCG-750 750W High Current Gamer Power Supply

Its $40 cheaper then my previous selection, so thanks for the help guys :)
