Can my corsair 620hx power two gtx 460's?

Hey all.

I recently upgraded my system and am waiting for the parts to arrive in the mail this week. My rig will be as follows:

Case: Antec 902
Mobo: Asus M4N98TD AM3 980a SLI
RAM: G.Skill ripjaws 4GB DDR3 1333 Cas 7
CPU: AMD Phenom II x4 955 Black
HDD: Western digital 750GB Caviar Black 32mb
OD: Samsung DVD burner
PSU: Corsair 620hx 620w
GPU: EVGA GTX 460 1gb.

I know my PSU will run this system just fine.
My question is down the road a year or so I plan to add a 2nd 460. Does my PSU have the power to run a second 460 with those other components? The only other thing I might add is a BD-ROM drive. But I can forgo that to add the second card.

Thanks for the thoughts all!

  1. Drop your Rigs specs in here and see what it recommends man,
    http://www.thermaltake.outervision.com/
    Try it with one and two gfx cards to see the difference :P
    could also check out the Bluray while your there
    Moto
  2. The corsair is known to be able to output more wattage than what's labeled, I think it might work. But you might want to hear everyone else's opinion
  3. I'd give it a go with mine, when (if) they release a 384 core version of course.
  4. Here's some screenshots from sites that have benchmarked it. A nice rough idea of the power consumption:







    Note that all of their testing systems used an i7 CPU instead of any AMD based processors. I would get the Corsair 750HX just to be on the safe side.

    All of those results are based on the AC side, actual DC load on the psu would be 15-20% lower, depending on the efficiency of the psu used.
    The HX620 would be safe enough.
  6. Max TPD for the GTX460 is 160w.

    You should be fine in SLI as long as you don't go nuts with the OCing.

    Yay! Long time no see, you should really post a bit more often and get rid of that "Apprentice" tag.
  8. Thanks for all the replies peoples!

    I will be holding off on SLI due to money for a while anyways. But its good to know its not crazy to try SLI with my 620w. I don't really overclock at all anyways. Maybe a touch on the CPU
  9. Here's a tool to calculate your PSU capacity

    Other PSU vendor such as Antec, Cooler Master have PSU calculator on its website.
