    Question What graphics card could I get away with on a packed system w/ 450W PSU?

    I have a Corsair 450W VX PSU, and am thinking about giving myself a little boost in games with a new graphics card to replace my 512mb 4850, but not sure what I could get away with given that there is quite a lot of stuff in my system already.

    -Q6600
    -2x2GB RAM
    -3 SATA HDDs
    -1 DVD drive
    -3x120mm, 1x140mm
    -Fan controller

    Everything is running at stock, but even so, with so much in there I'm just a bit worried that I'd be pushing my PSU to the limit, and potentially make it unstable. The PSU allows for 33A on the 12V rail, with a maximum output of 396W.

    Right now I'm looking at something like a 5870, 6850 or a 6870. I asked another forum, and they said I could easily run any of them, but I'm not convinced.

    TDP of all the cards is what you want to look for..

    4850 - 110W
    5870 - 188W
    6850 - 127W
    6870 - 151W

    Based on that, I'd say your system could definitely run any of those, and maybe be pushed a little by the 5870 but should still be absolutely fine.

    Welll 6850 with ease
    6870 should be ok
    5870 will be pushing it.

    Of those card the 5870 is actually the fastest, but that said a 6850 or 6870 should be able to happly cope with any single monitor setup.

    6850 is probably your best bet, for performance/stability on your psu
