AX850 enough?

post #1 of 14
Thread Starter 
Hey Guys, (and girls...)

I'm planning a new LAN party build, in a 650d and I am uncertain about the wattage I need.

rig:
Corsair Obsidian 650D
ASUS Maximus IV extreme
Core i7 2600k (@ 4.6-4.8ghz)
8gb Corsair Vengeance (@ 2000mhz 9 10 9 24)
2x EVGA GTX 570SC SLI
1x OCZ Vertex 3 SATA3 120gb (Might raid 0 two of these, not sure yet)
2x WD Caviar Black SATA2 2tb RAID 0
Corsair AX850 or AX1200
Corsair H60 or H70
1 dvd burner
ASUS Xonar Essence STX

Gonna be changing out alot of the stock fans, most likely getting a CM MegaFlow front intake, and 4 Aerocool Shark 120mm for top exhaust and H60 push/pull intake

So, what do you think, is this a viable build, wattage wise, or do I have to cough up the extra 90ish euro's for the AX1200?

Any help is greatly appreciated

Djac.

Well IMO it will be enough, but I don't know if there is much room left for wattage consumption. I'm not a PSU guru though, maybe someone else can fill in the blanks for me.

A 750w would be more than enough for that setup, including heavy overclocking. 850w is only necessary for GTX 580 SLI.

Thanks alot, I'm gonna go with the 850, since it gives me room to upgrade later on, when the 600 series come out.

Your rig will only pull around 550watts at the very most. A good 650 Unit will be more than fine. You could look at the corsair HX750 or the Antec EA (EarthWatts) 750w. These are more than enought power.

To answer your question OP that PSU is a bit much. But it's good for future upgrading.

Not even necessary for 580 SLi. They will pull ~ 250w each in games heavily OC'd plus 100w+ for an OC'd CPU will leave him around 700w total GAMING load.

But I could be wrong.

They can pull up to 280 each in games.

Hm. Is that figure overclocked or stock clocks? But even then that's only 560w combined.

Should still run on a 750w right? Cause he'd still have about 200w to play with for all his peripherals.

The Corsair AX850 is more than enough. As a matter of fact you can run SLI GTX 580's with the AX850. Just save the 90 euros for something else.

750 Is fine, hence why i reccommended 2 750's

Well, 25wx2=500w with 200w CPU = 700 along with ram, motherboard ect, a 750 will just be enough. This is full TDP though! He will only pull 550-600 at the very most in games.
