    Even though Im embaressed to say...its an NZXT psu.

    Hello

    The 650w ver is $149 @ newegg.
    I see no reason it wouldn't run well for you.
    Have you installed the 7800gt or waiting to buy prior to knowing about this psu?

    I've been having problems with the card. It's been either overheating *which i dont think it has*

    Or i don't have a PSU capable of runnning.

    From nVidia Q: What power supply does it require?
    Current recommendations are 350W for single, 500W for SLI.
    What are the spec on the rest of your system?

    Can you post the rest of your system specs for us.
    Also go here and calculate what need:

    The amps on the 12V rail are the most important, for a card like that and if you have an AMD 64 or P4 3GHz then you're going to need 26Amps or more.

    Cheers.

    When you say Ahtlon 3500+, this is the AMD64 3500+ right?
    Oh the PSU it's from NZXT case, ahh yes, my Nemisis case had a 450W jobby in it. I blew the crap outta that in a week with my lowly 6600GT, (AMD64 3500+) Mine went up in smoke, black smoke.

    Buy a new PSU quickly. In my sig see the pic of a good PSU for your rig. See the amps on the 12Volt rail? To run your 7800GT and the AMD64 with comfort you're going to need a 500W unit with 26Amps. Click on my BSODs link in my sig. Scroll to the PSU section, there's a link there to PSU specs. This gives you a complete list of all PSU on the market by spec. Find the one you like. Antec, Thermaltake, OZC are some of the best manufactures.

    Cheers.
