  1. I currently have a dell E310 dimension w/ a 230 w power supply
    i want to upgrade to a ATI Readon 9250 PCI video card which requires more power
    I have a Thermaltake Purepower 420w power supply which has a 20 pin connector--the motherboard has a 24 pin socket. there is also a 4 pin plug from the power supply . will the computer work with the 20 pin connector or do i need all 24 connections? --is the 4 pin connector supposed to make up for the extra connections?

    Should work fine with the 20 pin, but there is another spot on your board for the other 4pin


    the power supply should have 2 cables, the 20pin(or 24pin) and another cable with 4pin, both of those go in differnet spots,

    and from what i know it shouldnt be a problem with the 20pin going in the 24pin.

    Wait for more people to reply i might be wrong

    if you have your PSU's cable like This ,then you can just snap back the other 4 pin
    connector,so you can have 24 pins all together for your mainboard.

    the other 4 pin connector that sit's beside the 20/24 pin connector is the main power plug to your mainboard & that is different.

    you can use a 20 pin to 24 pin converter/adapter if you dont have the conventional (20 -24) molex connector out of your 420 W PSU.
