    Is this the Full size one or the tiny one from Dell? I looked up 745 and it comes in two form factors it looks like, since you said desktop im assuming the bigger version. The problem with Dell is that they usually make things custom and hard to change between, with a Pentium D CPU your options will be limited, what is the budget you have and which size do you have (Just for conformation).

    So its not the really skinny machine from Dell right?

    Ok your best option is something like this:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817371045
    a 400-450 watt PSU in a low end price range will be fine for your system, but make sure to at least stick with a good brand like Antec, coolermaster, EVGA, etc to prevent problems.

    This is a GPU in your budget with a PSU, it will be ok for gaming but if you play at 1080p your going to struggle.

    Edit: Oh its the Skinny one...Ok that limits things just a sec

    Try that, though it goes over your budget you need a low profile video card.

    The other thing is you might not be able to fit a full sized PSU, actually im pretty sure you cant. You may just want to get a low profile card and run it on your current 280 watt as based on the wattage needs it should be enough. Otherwise your going to have to find a PSU that will fit in that small a case.

    Just for your reference Kexin, the back of a standard ATX PSU is 85mm high x 150mm long (at the back, measure your current one to see if a normal ATX will fit.

    This is what I did with this optiplex 745 (mini tower) notice the revision of cpu is G0 notice the bios is 2.6.4 also notice I used 350 watt brand new power supply (any standard atx power supply will fit the minitower only) and it has the cooler from dual core cpu the pentium 4 cooler will not work and cpu revision must be G0 also pc2-5300 or pc2-6400 will give you max performance and hd6570 will use only 44 watts max and have very good performance for this very small amount of 44 watts 1.png 2.png 3.png 4.png

    I payed $70 for the hd6570 and it worked with the dell power supply that came with the pc just an fyi for people who want a video card for the mini tower under 75$ I put a new power supply only because it was old and I didnt want to fry my brand new gpu and the cpu I just payed $50 for on ebay
