In the past I have under sized one of my PSU needless to say burnt it out
took out the sound card and vid card. Ever since I tend to over size them
sometimes a little to much

NEW COMBO

GIGABYTE GA-X48T-DQ6

TWO SAPPHIRE 100243L Radeon HD 4870 In CF mode

Intel Core 2 Quad Q9550 Yorkfield 2.83GHz

CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1800

FIVE Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive

Was thinking of a 1000Watt but might be a tad big?
 
quad core + 2 4870... Quad would be around 230watts and single 4870 would be ~200 (some volt mods).

These are pretty conservative figures so a good 750 would be enough IMO. Get a tx750 or pc and power cooling 750. If you're feeling lucky, then bfg-800.
 
Welcome to the forums!

Overkill? See my sig. I just replaced my CWT 1200W modular with a Silverstone 1200W non modular. In your case, a good 750W would do the trick, like the Corsair TX750 or Silverstone OP/DA750.
 
OW, why 1200watts? I mean, single 2600 and 2 3800+

Let's just say if I'm going to have these things sitting around, I like to put them to use. The Silverstone was a review sample for Monday... won't be too hard to figure out why I'm keeping it around once that review goes up.

The office rig is actually pretty similar, only it has one hard drive. It's running off the 550W Glacialtech I reviewed a while back.

I can vouch for the Silverstone OP line. I have a 650 and it suites my needs and unless you are going to run 2gfx cards 750W is about all you will need.
 
Antec 850 TPQ? not many ppl choose products by their looks, but iv'e read great reviews of this psu; has great efficiency, is quiet, cool.

has racing stripes on it xD

if you're running 4870 in Xfire, might need 850. if a quad takes 230 watts (taken from a previous reply) and 2 4870's take about 250 each, that's already 730 watts. then you have your HDDs, DVD drives, Sound cards, Fans, and other periphrials or hardware. 850w shuold be perfect :)

Rich,

The 4870s in CF are about 250w total, not each. That Q9550 Yorkfield is a 95w CPU. Overclocked Crossfire and the Q9550 might add another 100 watts. That's about 450w overclocked at a guess and reinforces what Oklahoma Wolf suggests; that Corsair 750 would be just fine.
