That's for the GPUs alone, like they say at the top of their page.

I'm wondering how much power the entire system will draw with everything at full load with the 670s and the 2500k overclocked. My 2500k is at 4.5Ghz @ 1.35Ghz right now and it'll stay that way.

I would just get a NZXT Hale82 if I were you. The HX units are overpriced, at least that's my opinion.

With high overclocks and ov on the 670's, and a mild oc & ov on the i5, with 4 sticks of ram over-volted and overclocked (mild), a sdd, a hdd, a odd, and about 10 case fans, you would be drawing any wheres from 700 - 750 watts of total power. Go with a 800w unit if this is similar to your future / current build. Helps future proof the build a bit, for upgrades and what not. biggrin.gif

Without knowing your exact build this is just an estimate. Figure out your exact needs by using the program listed bellow.

I hope this answered your question geoxile.

That's actually looking very attractive to me right now...I just might, + rep for bringing that to my attention, I only thought NZXT made cases tongue.gif....only thing though, newegg says it has 53Amps on the +12v rail, but the picture says 62. So I'm assuming the picture is right.

62A is the 750W model. 53A is the 650W model, the picture is probably wrong. You can do the math for the 12V rail by multiplying A by V and it should be very close to the final wattage, 636W on the 12V rail in this case. Anyway, the Hale82 is a very good unit and shares the internal design of a similar but much more expensive Seasonic unit IIRC.

Anyway... I think I might just skip the 670 it seems.

I hope you mean newegg is wrong, not the picture. I've looked elsewhere and the NZXT Hale 82 750M has 62A on the +12v rail, but newegg's description says 53A. So I'm assuming they made the mistake of putting the NZXT 650w's specs on the 750w page.

Oh, I thought you were looking at the 650W. Maybe you should let them know about that

You have an incredibly high-quality PSU. I have no doubt it can handle peak load for a good while with ease.

Guys

I bought a Geforce GTX 670 card for my i5, 24gb Ram and Solid state hard drives. I've got 3 hard drives, 3 fans, 2 Firewire cards for my pci audio and DVD writer.

I'm trying to produce in Adobe AFter effects but the Rendering is extremely slow.

The Afterburner app for my Nvidia shows that there is ZERO GPU performance wile rendering?


MY QUESTION IS : IS MY CORSAIR 600 WATT POWER SUPPLY STRONG ENOUGHT TO POWER THE CARD CONSIDERING ALL MY HARD DRIVE, pcI CARDS AND FANS?

It's way more than enough.

 

http://www.guru3d.com/article/geforce-gtx-670-review/8

 

Their test system pulled 279W from the wall outlet when their GTX 670 was under full load.  Even adding 200W (unrealistically high) to account for the CPU and everything else simultaneously under full load only results in 479W being pulled from the wall outlet.  Then if the PSU is 85% efficient, then that would mean the system pulls a maximum of about 410W from the PSU.  ;)
