More about confirmation mobo
  1. Get a new power supply. Even the Sapphire 7750 requires 400W. GTX 640's all require a minimum of 350W with 20A capability.

    You're really going to be hampered with that 305W PSU. As it stands, you're probably right with 55xx or 56xx series.
  2. So here's what we know so far.

    1. You listed a bunch of random part numbers.
    2. Can't use google.
    3. Can't get the 20,000 responses saying pcie is backwards compatible
    4. somehow found a random Toms forum post that goes on forever and isn't about you? did you want us to read it to you??

    PCIE version does not matter. Google your board if you want your version, or better read the specs. Get a 7750. It doesn't need pcie connectors

    And DON'T listen to this Guy. Anyone who believes manufacturer specs for GPU power requirements should NEVER answer a question on GPUs. The 7750 takes less than 60W.

    and power use goes DOWN with new generations. Old ones, like he is suggesting. Use more power for less performance

    Ummm . . . the 7750 IDLES at 90W. Under load it can pull over 200W. I see you're rated as a "Graphics Card Master," but--aside from your being terribly rude--I see no evidence of it here.

  5. 3. Can't get the 20,000 responses saying pcie is backwards compatible

    Lets make my point simple, look what Dell installs on yours and similar systems
    Visiontek® Radeon 7750, here you can check 2 links, don't confuse yourself that cards are low profile - they still 7750, once you open the link scroll down to Compatibility
    Scroll down there until you find your model

    In such cases, when user is lost in "20,000" comments, it is a good thing to look at your PC manufacturer"
    Quote:
    Compatibility This product is compatible with the following systems:

    - Dell did the testing, so just relax, don't pay attention to above statements. This is where user experience outweighs paper.

    Knowledge is the POWER.
  10. thanks dude!,but i look at the PSU(in your link) but only the psu that comes up with my system is in there,so foes that mean,no other psu is compatible with my system?

    Id this the same http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=A6282698&mfgpid=204067&chassisid=8849

    Anyway, in your (mine) link just scroll down to video cards, click arrow down and all video cards open, 7750 is there and I think it is second from the left?!
  12. As I was surfing problems, I got to your post http://www.tomshardware.com/answers/id-1685641/decided-psu.html

    I can add, when you scroll and found your model from my links, have you seen abbreviations like DT and SFF after the model number - they mean smaller form factor PC with SMALLER POWER SUPPLY!
    So you have enough, also most of Dell PSU are rated underpowered - they are actually stronger, so nothing to worry here.

    In the same post someone stated about proprietary power supply connector to motherboard - answer is not, all standard here.
