Question Gtx 750 ti

[ErnestoGP]

Will it fit on my dell optiplex 790 dt?

Looks like you'd need a low profile card

And will depend on the PSU that's in there too.

A GT1030 might be a better option to consider. Lots of low profile variants around, and a lower TDP.

I have a 250w Psu

 

[Barty1884]

250W peak, maybe. when it was new ~8 years ago. You almost certainly don't have a PSU that can reliably do 250W sustained in 2019.

Does it matter what kind of gt 1030 I get?
