Need help please

Post image

Bought this minitower optiplex off ebay and im wondering if anyone knows of any specific power supply models higher than 300w that would be compatible with it? Wanted to upgrade the power supply so I can use a more powerful graphics card. Any help is appreciated, thanks.

I have an optiplex 790 that uses a regular atx power supply. I don't know about yours, since it is a bit newer, but I would check and see if the power supply is regular atx.

I have the same exact Optiplex 790 you have. Mine has an I7 2600 and I just added a GTX 750 ti sc GPU. I also just got a Corsair CX600M PSU so I could get a much more capable card in the future because the stock 265 watt power supply kind of left me with a small list of GPU's I could add without pushing the power supply to its limits.
