  1. Hi!
    I am buying some new parts for my PC and wonder if a 850 PSU will be enough.

    GPU = XFX Radeon HD5850 (500W)
    CPU = AMD Phenom II X4 965 Black Edition (125W)
    CPU Liquid Cooler = Corsair H50.
    MB = Asus M4A785-M
    RAM = 4x1GB DDR2 800MHz
    Case = Cooler Master CM690 (With 4 Case Fans)

    Of course I will have a DVD player and some usb devices connected

    The PSU I will use is, Corsair TX 850W PSU.
    Is it enough to run all this smoothly?

    Responds would be appreciated. :)

    The Corsair TX 850W will be plenty for your application.

    You sure?

    With one 250GB Harddrive and one 1TB?

    Should be fine. I don't think a Radeon 5850 eats up anywhere near 500W...
    Out of interest, is there any reason why you're going for DDR2 memory?

    The Corsair 650TX is good enough. However, in case you'd like to add another GPU in the future, the 850TX is a great choice.

    Well, I already have the motherboard and ram, and I didn't feel like buying new motherboard (yet) since it supports AM3.

    Corsair 650w is great.
    BTW, its usually better to go with 2x2 instead of 4x1.

    "How come" what?

    How come the Corsair 650TX is great? It simply is.

    How come 2x2 is better than 4x1? That's because the memory will be operating in dual channel giving better performance.
