Default What power supply for sli?
Hey - quick question, What power supply would be ideal for the following set up?
evga 780i
o/c q6600
antec900
2 8800gts 512 (sli)
4 hhds
4gb ram...
If you can't recomend a specific model I would also like to know how much power I will need... Currently looking at 850W models

I run my setup on a HX-620 - best PSU value for money vs performance available and will power it all fine

850 would be overkill, and the Corsair PSU will last for a very long time - modular cables to !

Yeah, a quality ~650W psu will be fine. I've always liked corsair.

The corsair hx 620W looks like the best option judging from its reviews and whatnot. Thanks for the advice...
