    Depends on your graphic card needs and periphials that need extra power to be run

    ussualy 500 to 550 watt is good enough but if you want a little more headroom for future upgrades get atleast a 600 watt or greater

    Not much.

    The system below, with your video card, uses under 300 watts under load and under 200 at idle. Your i5-2400 will use a bit less than the test system's i-7 920.

    I'd get something in the 400 to 500 watt range unless you intend to get some other graphics card.


    Processor: Intel Core i7 920(ES) @ 4.0Ghz (Turbo Mode Enabled)
    Memory: Corsair 3x2GB Dominator DDR3 1600Mhz
    Motherboard: Gigabyte EX58-UD5
    Cooling: CoolIT Boreas mTEC + Scythe Fan Controller (Off for Power Consumption tests)
    Disk Drive: Pioneer DVD Writer
    Hard Drive: Western Digital Caviar Black 640GB
    Power Supply: Corsair HX1000W
    Monitor: Samsung 305T 30” widescreen LCD
    OS: Windows 7 Ultimate N x64 SP1

    According to http://uk.geforce.com/hardware/deskt...specifications, the minimum power requirements are 450W. Given that, I would recommend a psu of 650W.
