Will a GTX 750ti work with the stock (especially power supply) of a Dell Optiplex 790 SFF? The wattage says "240 w".
Ran across a pretty good pic of the inside of one:
Dell Optiplex 790 MFF – 5 (Win10) – RefurbIT
It appears that you have room for a half height card which would take two slots. I would double check length because it looks pretty tight.
As to your PSU, I believe the 750ti will be fine on that aspect. They are a sub 75W card and don't require a(supplemental) power connector.
Can you tell me of a cheaper card? (all I want to do is play counterstrike G. O. on good settings) that will fit in this dell optiplex 790 SFF case? This one doesn't fit. Someone gave it to me. I can trade it for a card that fits my pc BTW.
A 750Ti won't fit a SFF case. You need a half height card. A 1030 with GDDR5 memory might be your best option with a 240W PSU.
I can't afford that. Any recommendations for one that's substantially betterthan this dell on board video motherboard?
Anything that would be cheaper than that, would also be a lot slower, like an OEM R7 250, which I think would be completely useless as a gaming card. Maybe if you ran games in 720p with low settings, it might work, but over that, probably not.
I just did some searching, and r7 250 delivers about half the frames of a 1030, and there are games that won't run at all, so not really acceptable.
You could certainly get GPUs for <50 that outperform the integrated graphics, but still, none of the GPUs under $50 are going to be of any use for modern games without some SERIOUS graphics setting cuts.
I have yet to see one. They must be really rare.Low profile 750ti exists
