    Ok, So I've built my own PCs for some time now. However, my power supply is some thing I've always been a bit iffy on. I've put a lot of money into my PC (Which by now, what was the high-tech stuff is now ancient.) and I'd love to put a lot more into it, but I am trying to be a bit tight on my spending.

    My problem is, Power supplies, are of course, pricey; and I'd like to upgrade my PC graphics, by buying two 8800s and using SLI. I am currently running -

    *CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
    *Intel Core 2 Duo E7200 Wolfdale 2.53GHz LGA 775 65W Dual-Core
    *ASUS P5N-D LGA 775 NVIDIA nForce 750i SLI ATX Intel Motherboard
    *Sony NEC Optiarc 20X DVD±R DVD Burner Black SATA Model
    *MSI NX8600GT Twin Turbo GeForce 8600 GT 256MB 128-bit GDDR3 PCI Express x16

    I also have a 500 gig ATA100, as well as a 250 gig ATA100. I am currently running off a nice quality 500 watt. I am hoping to buy two 8800GTS cards for SLI and use them in place of the 8600 as well as by a 3rd HD, probably being a 500gig Sata/3g.b

    Now I honestly don't know what kind of power supply will be needed to run my machine once all the new pieces are in place. I am almost positive that my old power supply won't be able to support it. Any ideas on what would be a "Safe zone" for the PSU and I don't need overkill, because I'm trying to save some money here. :rolleyes:

    Any suggestions will be helpful!

    (okay a paste from me)
    9800GT which replaced the discountinued 8800GT is what you should look at:

    9800GT singe slot: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130380
    9800GT Dual slot: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130397

    Note: 9800 / 8800 cards generate a lot of heat... You may want to look at a bit cooler running ATI 4850 card... or the slower 4670 card. A dual slot card will help exhaust the heat.

    Top level PSUs:
    OCZ, FSP, Seasonic, Corsair, PC Power & Cooling, Zalman, SilverStone, Gigabyte

    Good PSUs:
    Antec, Enermax, Sparkle, Coolermaster. (some of these are TOP end)

    Should Avoid:
    Aerocool, Apevia, Apex, Athena, Chieftex, coolmax, Dynapower, e-power, Linkworld, Powmax, raidmax. Many of these are exactly the same thing.

    I'd say a good quality 750~850watt PSU should handle that.

    Don't ever cut yourself short on a power supply. You can have the finest motherboard, processor, video cards, etc., but if you don't have a good quality power supply, to supply the current you need, you have nothing.
