In order to upgrade Small Form Factor to GTX 750TI you MUST find a place for you hard drive or heavy mod hard drive caddy (I would not be able to help you with modding).

This card reported to work on Dell power supply of 234 watt and non Dell power supply of 200 watt

MSI GeForce GTX 750 Ti N750ti-2GD5TLP 2GB 128-Bit GDDR5

This is your PC

Note that fat card will not fit due to hard drive caddy, so if you can place hard drive elsewhere and free space next to video card, you can instal MSI GTX750TI.

Thank Kisianik . I see your card you provided have required Minium 400 W power supply and i just can see SeaSonic-SS-300TFX PSU can fit with my sff case but it only supply 300W .

I can remove my hard drive and put it below my dvd drive . It's fit. I'm sure.

My system : CPU: Q9650 . RAM 16GB and VGA Readon 5450 HD

So can i use your card : MSI GeForce GTX 750 Ti N750ti-2GD5TLP 2GB 128-Bit GDDR5 ? with 300 or 235W Supply ?

Go to Newegg link I provided, next go to reviews page 2 and read user's statements, you will see what I mean. You have 235 watt power supply, it is enough.

I agree GTX 750Ti uses very little power. PSU should be OK.
If you didn't already have the Q9650 I would suggest the Q9505s or Q9550s 65w quad CPUs. Then CPU +GPU= 130W.

If your computer has floppy drive that you don't need you can get a bracket for a laptop HDD, or SSD to go in there.

It will fit with minor modification. My brother is running the same card in his OptiPlex 960 SFF. He relocated the drive and had to remove a very small piece of the plastic shroud from the card in a corner in the rear with a dremel but it will fit and work great.

I know this is an old thread but I am doing the same thing. Just got a bunch of free Dell OptiPlex 780's from work and put a Q9650 CPU and 16GB 1600U DDR3 + 750 Ti. I purchased a floppy drive to 2.5" x2 ssd caddy and a dvd drive to 2.5" ssd caddy so I can set raid 0 with 3 ssd's. Only about 700MB/s with sataII though. As for the power supply there is actually a 500W that will fit out of the Dell vostro "500w TFX Power supply" but since the 750 ti is the best SFF video card that will fit and works just fine with the oem psu there really isn't a point to upgrade.
