    Not as much as you might think, honestly. Your video card probably draws about twelve amps on the 12V rail, and the whole machine will be fine on about 450 watts after factoring in a thirty percent safety margin. More important than a big supply is a reliable one with good rail regulation and low ripple.

    Check these links:

    OCZ StealthXstream

    (FSP, rather high ripple at full load, cheap)

    Corsair VX-450

    (Seasonic w/ all Jap. caps. Really peaks at about 600 watts)

    CoolerMaster Real Power Pro 550

    (Enhance, overengineered)

    Oh, and while you'll outgrow these if you want SLI (why?) and a good safety margin, current prices make it not much more expensive to buy one of these and later upgrade if you decide you need more power. That way you get a spare supply if nothing else.

    You might need 550-650 watts, but since you are building yourself a pc, you''ll probably want to upgrade it later on. Therefore, you should buy enough wattage to add stuff in, so go for maybe 750-800.

    Make sure you at least have 80% efficiency (look for an 80 efficiency brand, because some batteries only give you their efficiency at top output). for the 550-650 batteries, you could probably do much better than 80.

    I highly reccommend a corsair Power Supply. I have a TX-750 (750 watt).

    You can go for the modular series (HX) if you want keep the case tidy. (You can unplug the excess cables from the power supply)

    A HX-520 would be sufficent but i'd go for either a HX-620 or TX-650.

    They have a five year warranty and a very good reputation.

    Go to www.staticeice.com.au to find the cheapest price for an online store.

    like the others have said 450 is the recomended but why get something that will just do the job when in a few years when you have more money and things demand more and more power (it is only very recently that graphics cxards required additional power and nobody had any psu over 500w) you will regret having boaught what will just do the job so do your self a favour and buy the better power supply now rather than having to spen more latter on i would do for a 750w

    ps good to see people freeing them selfes from the grip f dell and the other computer suppliers good luck :)

    Id get a 750 watt, an 850 if you plan on going SLI in the future. newegg has great deals on power supplies by the way, they're selling 850 watt PSUs for 100 bucks less than they normally cost http://www.newegg.com/Product/Product.aspx?Item=N8...

    A 600 watt Power Supply will suffice all the components at max load. Just try to get one from a known brand.

    There are some insane recommendations listed here... I'm running a quad core with a 9800 GTX on 500W atm. If you plan to SLI in the future then you might want to pick a higher wattage PSU, but otherwise, the 500-650W range is plenty.

    A kilowatt powersupply is overkill, even in terms of tri-sli.

    Neither requires that much of a large power draw (gaming machine wise) and you can get away with an Quality 500W 80+, 85+ certification PSU. Of coz to be safe you need 600W+
