  1. If you're not overclocking 450W would be plenty, otherwise I would go to at least 500W.
  2. Yeah you will probably be OK. The 8800GT uses alot less power than the other 8800 cards.

    But there is only one way to be sure. Do the book keeping and add up the power draw of everything in your case. You are listing only 3 components, but you have other things in use. Plus you want some extra margin, at least 20% over what you think the max draw is. And you have to account for anything you might want to add later or any OC you might want to do. It sucks when your PS causes problems, it is better to be safe.
  3. 450w should be enough for a non-overclocked system as stated.


    DO NOT get some shoddy non-brand name PSU and expect it to work. Get something decent. CorSair450W is nice as is the AntecNeoHE although i think they start at 500W
  4. Corsair 550 Watt Power Supply. Link: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004
    Reasonable priced, and high quality. Would allow you to have 8800 gt sli if you wanted.
  5. Go for at least 600W. Be safe.
  6. It might also be wise to check the 12v rail amperage... an 8800GT is going to need about 22A (please correct me if I'm wrong)?
  7. It certainly depends on whose PS you use. A cheap PS's specs have to be taken with a grain of sale. The Corsair 550 mentioned above is super as is PC Power & Computing models. Try some PS reviews at jonnyguru.com
  8. Hi all,

    I was comming to ask more less the same question and saw this post.

    I have the following:
    +Maximus Formula
    +Q6600 @3.5
    +antec 900
    +8800gt oc2
    +2gb corsair dhx
    +1 HD SATAII

    All this supported on a Antec TruePower II 480w.

    My CPu is prime stable and the 8800gt is giving me 14283 3DMarks

    Everything looks good, no crashes, games are...well..i guess normal (i used to play with a 1950pro, so everything looks better than tat! ;)

    But seeing your responses i wonder if i'm playing over the limit or i'm giving a hard work to my PSU.

    Do you think i should upgrade, even when everything "looks fine"? i'm really a noob in what psu matters! :(

    EDIT: BTW, i read the FAQ at the top here and is too much for me ;) i checked the "eXtreme Power Supply Calculator Lite v2.5" and is giving me a 392w but i never trust those calculators ;)
  9. Your fine u2vini... Thats a strong PSU and the 8800gt's are much better on power than there g80 counterparts.
  10. For the OP a quality 450w is plenty for a single video card setup. 8800GT cards use about 110w MAX under load so I don't think it will ever pull more than about 9-10a. The VX550 will give plenty of headroom if the OP is going to have LOTs of drives or an extreme OC on the quad. Even so, the 450 is plenty.
  11. Dude, you need to look at the amps too.

    I agree that amps are important.

    And quality is a lot more important than people think.

    Coming from the car audio world, a cheap 1000w speaker amp sounds A LOT worse than an expensive 250w amplifier. The quality of power delivered makes all the difference in the world.
