Is this PSU good enough?

I bought this PSU on a shell shocker deal for $57 ($37 after mail in rebate)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028&cm_re=600_cx-_-17-139-028-_-Product
and was wondering if it could eventually power dual 6850's (no plans to OC, since I doubt I can OC dual 6850's on a 600W)

I'm currently building my system and am waiting for bulldozer processors to come out before making a final decision on CPU, although it will probably be either a new bulldozer or a i5-2400 (from early rumors the bulldozer will probably be 95W TPD like the i5, I have no plans to OC the processor so a 2400 is enough for me)

I'm planning on running at most 2 HDD's and a SSD (future upgrades starting with a single 1tb F3)

my current resolution is only 1440x900 so I know a 6850 is enough, however my first future upgrade will probably be a 1080 monitor, and I want to beable to upgrade to crossfire in the future

If the PSU is not enough, I'm debating buying a 6950 right now instead and overclocking later if I feel the need

I probably won't respond for the next two days since I'm traveling but I will look for recommendations as soon as I get back

More about good enough
  1. For whatever reason, that link doesn't work. What's the PSU model?
    What do you mean, no plans to OC? Why the heck not?
  2. No, According to some PSU calculators and myself, a 600W PSU can't handle the two 6850s anf i5-2500 and your remaining setup. So at least get a +700W PSU

    It would work imo! since a 6850 only needs one 6pin pcie lead..
    2X6850 = just under 400W on an oc'd i7 965 full load entire pc.

    You're not using an i7 9xx cpu.
  4. Oh you're fine. Throwing in five fans, and a couple of external USB devices, with 10% capacitor aging (even though this is a new system), I got only 476W using the PSU calculator at http://www.extreme.outervision.com/PSUEngine. Enjoy your build.
  5. agree, will work fine. You could run 2 6850's in crossfire if you really wanted to.
  6. You'll be fine. A single HD 6850 consumes about 90w under normal gaming conditions and an i5 2400 consumes about 55w @ 100% utilization.
  7. I think the TDP of the 6850 is around 130W. I know its more then 90W. Two in CF would be 260ish, round up to 300W for your board and other stuff. Even if you were using a 95W CPU, your still at just under 400W for the system. Your PSU has a single 40A rail, so you have 480W available. I agree that you should be fine.

    But there are some 6850 that need two 6 pin pcie lead, like my ASUS EAH6850 DC/2DIS/1GD5/V2, but then again, it oc's great ;)

    even if it needs 2 6 pins, you can just use adaptors. there is no real reason to have 2 6 pins, they dont use that much power.
  10. Thanks for all the replies guys, I guess I'm going to go with 1 6850 for now and upgrade to crossfire when I feel the need
