Is this the tower, desktop or sff version of the Optiplex 790?

You may be able to upgrade the power supply if it is the tower version.

I have seen both Dell and others mention with this model, the PCIE slot on the motherboard can only supply 35w, which may be something important to keep in mind.

See if the case can take a new PSU. I can't seem to find a straight answer on google, but it looks like a standard micro ATX case.

Then again it is Dell so it may or may not not take a standard ATX PSU. If it can though, then you'll have a lot more options of graphics card to choose from.

Apparently, Dell's manual states that the PCIe slot is limited to 35w MAX. That said if you can fit a new PSU then that shouldn't be a problem.

If you cannot upgrade the power supply, you are limited to 35w graphics cards. The best of out those is the R7 240.

i cant use the R7 240 because it needs 450W or greater power supply.

Take a picture of the PC or find it on the Internet and post a link.

Its a 30w card. Uses less power than the GTX 750ti, which can run on a 300w power supply so your PC can definately run it.. However the R7 240 is not an impressive gaming card anyway, performing around the level of a hd 6670.

Best thing to do is to upgrade your power supply, else you are going to be very limited.

Skip to page 19, and look at the expansion slots. Without a PSU upgrade, you can't even run a GTX 750ti because the motherboard can only supply 35w.

The R7 240? That shold work. PCIe 3.0 graphics card can work with PCIe 2.0 motherboards and vice versa.

Keep in mind, the R7 240 is not a particularly powerful graphics card, it performs around the level of a HD 6670. Don't expect many recent games to run fluently.
