    I have a dell dimension 4600i with 1280 ram,a pentium 4 3.0gig processor.My graphics card has been upgraded to a GeForce 6600gt.Im thinking the graphics card is not getting enough supply from my power supply unit. I have been offered a winpower 450watt supply unit Will this be compatable? Ive heard that unless i use dell components it could burn my motherboard out.Could someone advise me
    Many thanks

    I'm just going to say what a more experienced guy is going to say.

    Go for branded makes such as antec, enermax, coolmax, and sparkle / fortron

    I had a winpower stock PSU in my old case, it has a 20a 12v rail. That's good. It ran a AMD Sempron 3000+, 1024mb DDR RAM, ATI x1600 pro AGP, four hard drives and a DVD-RW. Oh and 2 LED case fans.

    Is the PSU model: ATX-450?

    Yeh. That would mean stock, unbranded.

    Do you know what wattage your current PSU is?

    yeah, I am going to upgrade my Power Supply Unit (PSU) sometime in the very near future, so i am reasearching as well. I am upgrading from


    2x GeForce 6800 XT [256MB each]----->2x GeForce 7900GTX SLi [512MB each]. (I know a guy that got me OEM versions and gave me a 2 for 1 deal)


    From your specs of 250Watts, that is not going to cut it, and awill actually hurt the rest of the system. Of the top most important components in a computer, I would say that the power supply component is in the top 3. I am running GeForce 6800 XT in SLi and my PSU is Antec Neo HE 480.

    When you are going to purchase a power supply, check the efficiency details. For example, if you buy a PSU that claims to pump out 600Watts, but runs at 50% efficiency, you might as well be buying a 300Watt PSU at 100% efficiency (although no PSU is truly 100% efficient).

    I am looking at this PSU, Silverstone Strider 750W Modular edition. Although there are some things like 4 PCI-e pins in there that may seem redundant or unnecessary, I plan on future technology advances, and want to get something now that will accomodate advances in the future.

    For your situation, I would suggest a power supply from the Anteec HE series, probably something around 400W should suit you just fine.



    I hope that helps you, declan1969
