Powering a QX6700 System

[awinnerisyou]

Hey, guys! I'm a little stumped on which power supply I'll need for my new QX6700, X1950XTX system (a couple of raptors, 4 gigs of ram, dvd drive, not much else). I'd like to get a supply with enough headroom to be able to run top flight GPUs two years from now. Is a 750 or 850 watt power supply overkill? Looking for a supply that will be OK for me for the next two and a half years or so.

If you have a specific model that you think would be great for me, that would be a huge help!

Thanks!

Any plans for SLI in the future? If not, the Corsair HX520 or a Seasonic or Enermax unit around that wattage should be plenty.

Planning for GPUs two years off is hard. On one hand, they could continue with the current power-sucking trend, and require 1KW power supply for one card, or they could go for low-power stuff like Intel recently did with the Core Duos, and you'd need a 300W power supply for four cards The HX620 is *probably* a good bet either way, but it's a tossup whether it'll really be sufficient in two years.

Thanks for the reply! Running SLI or crossfire isn't something I'm really into, so I think the 620 will work great for me. But is it worth spending a little extra to protect myself if I someday want to run a dual card setup? If so, what would I go for?

Maybe a PCP&C Silencer 750 or a Zippy gamer PSU. But I'm not convinced that it's worth the extra money - a 620 will handle SLI 8800s, a core 2 quad, and lots of other stuff.

HX620 would be good for what you need... silent too and all black

Picked up the 620. Thanks so much, guys!
