More about will enough
  1. The Corsair VX550 is an excellent high quality power supply that can easily power a system with any single video card made, including a GTX250.

    Here is a link to a technical review of the VX550:

    http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=62

    Here are the official power requirements for the brand new ATI Radeon HD 5850 and HD 5870 video cards.


    ATI Radeon™ HD5850 System Requirements:

    PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

    500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended
    600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode


    ATI Radeon™ HD5870 System Requirements:

    PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
    500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended
    600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode

    The power supply recommendations are for an entire pc system.

    Corsair, PC Power & Cooling, and Seasonic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Lately we've been seeing a few other brands offering some high quality units.

    If you are in the USA, then newegg.com has the Corsair TX750 at a final sale price of $89.99 after mail-in rebate and shipping is free:

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006

    That's the same as the final sale price as the TX650.
  2. Keep your 550VX UNTIL you cough up the $$$ for a second 275. The 550 will work fine for now, even with the physx card installed.
  3. +1 for above. The 550VX will work fine for a single GTX275.
