    Maybe wait until you have more money then? Your PSU is the single most important part of your system, and you should never skimp on price or quality there.

    I am not sure I'd use a $60 PSU, also not sure if I'd use a PSU made by a case manufacturer. You'd be better off buying a brand that makes mainly power supplies, even if it's smaller than the one you linked.

    Maybe this one
    Newegg.com - Recertified: PC Power and Cooling Silencer 750 Quad Red 750W ATX12V / EPS12V SLI Certified 80 PLUS Certified Active PFC Power Supply

    or one of these for a bit more
    Newegg.com - Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply
    Newegg.com - Antec TruePower New TP-650 650W Continuous Power ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Active PFC "compatible with Core i7/Core i5" Power Supply
    Newegg.com - SILVERSTONE Strider Essential series ST70F-ES 700W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply

    Your old/current 600W one may be ok, I just checked and it has 2 x 12V rails @ 25W apiece so it might be ok. So maybe wait and try with the old one before ordering, that way you can test and see how it goes, then if you need you can order a new one and by then you might have a little more cash on hand. It's best to buy the best quality you can afford even it watts are not all that high, not the cheapest one with most watts, as that may not turn out as well as it sounds.

    Thanks for the great tips. I already ordered the card and PSU. The sale ended today and it was actually on sale for $49.99. I will try the new card with my existing OCZ PSU and if it doesn't cut it I will try the Raidmax and if it doesn't hold up I will get one that you suggest later and use the one I just on sale for a lesser power demanding build.

    Cool, well good luck with the new stuff once it arrives, hopefully maybe your old one will be ok and you can sell or use this other new PSU in another system.

    See how it runs on your old psu first,sapphire recommends a 500w minimum psu

    Recommended Power Supply
    500 W
    Peripheral / Interface Devices
    CD-ROM, two additional power connectors
    System Requirements Details
    - RAM 1 GB

    That leaves 100w to run the rest of your pc so I don't know if you'll be ok,only way to know would be to try it

    Check out HIS Radeon HD 6950 2 GB Review - Page 27/33 | techPowerUp, where it looks like the maximum power draw of a 6950 2GB video card is about 180 watts. When your system is heavily loaded, the rest of your system probably requires up to 250 watts. In general it is recommended that the total power load for a system should not exceed 80% of the rated power output of your power supply for extended use.
