Which works out to be around 364W DC considering my location (New Zealand, 240VAC) and 80+ Silver PSU.
Ya, but it only has 336w on the 12v, so id get the antec over that any day.

CX430 is good for 28A. CX430v2 is rated for 28A, probably good for 30A. XFX Pro 450W is good for 34A. That's the difference--not 20W, but 48-60W@+12V.

The GTX275 was a very, very power-hungry card for its time, more power hungry than the GTX285, barely topped by the GTX280. I put it in the same power class as an HD6970 or GTX570. So it's wise to step up slightly from the CX430v2.

I thought i linked the V2. But isnt the antec better since it has 32A, or that rosewill that has 33A? Im just concerned wit power draw. I want as MUCH power as i can get for the price. If you say the CX430 will power it AND its beterrer than the antec/rosewill i will get that.

Ah right I forgot that PSUs can have different +12V amperage ratings despite the same wattage rating lol.
