No, a good 600watt or higher will be good.

This is what it says on the specs of the cards.
Minimum of a 680 power supply.
(Minimum recommended power supply with +12 Volt current rating of 46 Amp Amps.)
An available 6 pin PCI-E power connector and an available 8 pin PCI-E power connector

Although it says 680w, a good 600+ watt will do the job. Remember when buying a PSU, look at the amps...most important thing.

Also for ram, get (3 x 1GB) or (3 x 2GB). You want to run in tri-channel mode.

I agree. Grab a PC Power and Cooling or Corsair or some other quality psu 600w or higher and you would be fine.

wow guess people really overestimate the powersupply they need

I thought he would need more but I guess it's the quality of the PSU that's most important (not to mention the 12v rails)

A simple HX520W would have powered your rig fine.

A 1200W won't hurt though I guess...

It uses 416W at max draw so 120W for cpu you are looking at a core component draw around 550W so 600W minimum by a good brand. Get this one Newegg.com - MSI N295GTX-M2D1792 GeForce GTX 295 1792MB 896 (448 x 2)-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

Alone in the dark isn't worth 40 bucks

I'd recommend either a Corsair TX 650 or 750 (the number also being watts); I have a 750 and it's very good.

im running my q9450 at 3.7 right now with an XFX BE core 216 OC'd (which calls for 40A according to XFX...NOT 38A as according to newegg specs...putting my psu 1A above recommended ) with a 550vx...and i have zero problems. its all about the quality.
OP i'd go with the corsair 750tx....it has plenty enough amps and will leave you a bit of headroom as well. the 650tx will cover your needs, but the 750tx is like 10 bucks more and has 8 more amps on its rail (60 vs 52).

Those recommended amps are probably overshot because they dont know what each consumer will have running in their pc.
