Will a NVidia GT 730 fit in a Dell Optiplex 745?

Recently my friend's laptop broke down and he gave me $100 while he was on a holiday to upgrade the GPU on his old Dell Optiplex 745 Desktop form-factor for him. The specs for this system can be found here (He has the Core 2 Duo version):

http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf

From what I understand, the PCIe 2.0 x16 164 pin slot can only supply 65 watts. The GT 730 was just recently released and the GDDR5 version (specs here: http://www.geforce.com/hardware/desktop-gpus/geforce-gt-730/specifications) has a wattage of 38W.

His system does have the riser option however I am not sure if the card will fit in the case (desktop form-factor) and if the low-profile slot will be too small for the card. He will be using it for about a month for light gaming till he gets his gaming laptop back. If the card is not compatible for one of the reasons above or another one I haven't realised, would you please be able to offer an alternative.

  1. As long as you have at least 300W power supply it should work.

    But Dell won't supply info on how long a gpu you can fit in their cases. You'll have to measure it. Is there a graphics card in there now.

    From the spec you can see you have to be able to fit a card that is 6inches long, 3 inches wide and will take up 2 case expansion slots.

    The GT 730 is just a rebranded GT 630. There are only 2 sizes for video cards, full size and low profile and if he has the "desktop" size from the picture you posted then you will have to get a low profile card. The GT 630, GT 640, and GTX750 all come in low profile, are all extremely short, and will work fine with just the power form the pci-e slot. The GT 630 is not going to be too great for games though, unless they are ran at a low resolution or a very low setting. You can get a GT 640 for about $80 or a GTX750 for about $110.
  3. If it had a graphics card in it, that would be as powerful as a GT630 anyway.

    Even the integrated HD3000 graphics would be near as good.
