Corsair GS700 any good?

post #1 of 6
Thread Starter 
Hiyya good people of OCN PSU section wave2.gif

I was wondering if this PSU would be capable of crossfiring 7950 OC to 1200/1500 and a 3570k OC to 4,5ghz. If not, what brand and wattage do you recommend me?

All that's needed for this is a quality-made 550W power supply:

 

http://www.guru3d.com/articles_pages/his_radeon_hd_7950_review,8.html

 

With one 7950 under full load in their system, their PSU pulled 300W from the wall outlet.  The 7950 by itself pulled 138W, so that would make the PSU pulling 438W from the wall outlet in Crossfire.  Their CPU was idling, so I have to add 150W for an overclocked 3570K which makes the PSU pulling 588W from the wall outlet.  So if the PSU is 85% efficient while pulling 588W from the wall outlet, then the system is pulling 500W from the PSU.  Your actual gaming power draw will be closer to about 400-450W.

 

Although, you'll need 4 x 6-pin PCI-E cables, so I recommend a quality-made 650W power supply.  I don't go by brand names though.  Can you order from Newegg?  How much can you spend?

It's the PSU I'm using ATM in my rig. I'm thinking between upgrading soon to the 3570k or waiting for Haswell, which I think is reported to be even less power hungry than Ivy(and much less power hungry than my current 955BE lol), throw another 7950 and profit biggrin.gif. The only downside I see it's that I only have 2x6 pin PCI-E, so I would have to use one of the molex cables I have tucked somewhere in my case with 2 molex to 6+2 pin PCI-E. That is, only if this PSU is capable for the job.

Yeah, via adapters that would work. Electrically it's enough.

btw there are two versions (though either is okay, the newer is a bit better). The older version has a more traditional wire fan grille and is 80 plus; the new version has the flat slats across, is 80 plus bronze, has a fanless mode, and has the colored stripe going around.

I don't see why Haswell would use less power under load than Ivy Bridge (when not normalizing for equivalent work being done). It's still on 22nm, though supposedly using different transistors, but it's got more execution resources and overall a bit higher complexity in the cores. It could use less, but it wouldn't be by a lot. It could be a little bit more. Depends. Anyway, I wouldn't expect any significant shifts.

It's much more than capable.
