I'd say the Nvidia GT 1030 is the most card you'd want to use. Overall it is very low power demanding, which is good since the PSU in that computer is not capable of supplying a lot of power. And it also uses around 30W from the motherboard, which is important since some pre-built computer motherboards are not always capable of supplying the standard 75W.
Potential issues are: the 1030 might have compatibility issues with a non UEFI motherboard. Look around to see if anyone is successfully using a 1030 on older Dells. Also, even if it does work, the 1030 is a low end gaming card. It's suitable for esports games, but not for things like PUBG at 1080p 60fps.
An alternative card is the Nvidia GT 730 DDR5. This card will be low power demanding like the 1030 but it will be compatible with older motherboards. The downside is it is less powerful than the 1030 by a fairly large amount.

Zotac makes 2 1080P capable cards that run off of the PCIe slot. The GTX1050 Mini 2GB, and the GTX1050TI Mini 4GB. Dell went to UEFI very early, Optiplex 780 and possibly the 760,755. here are many Opti 790 builds with GTX1060,1070, and 1080s.

Here's the Zotac Mini.

GTX 750Ti has been the go to card for a few years. it starts to struggle at 1080P and is DX11. The GTX 1050 is newer runs strong at 1080P and even goes above that, and has DX12. I t sells for about the same price. The GTX1050Ti has 4GB DDR5 and will run hgher resolutions than the 2 GB card. More performance, and more bang for the buck Than the 750. They alll run off of the 75W PCIe slot. That was the 750s claim to fame, no psu upgrade needed. The 1050 is the first card to beat the 750 at it's own game.
Other than that nothing wrong with the 750.

It has a 265w psu and supplys 30w to the pcie but you said the 1050ti and 750 ti use upward of the 30w and it would work fine with the psu?
The PSU should be OK. The 30W limit usually applies to SFF or USFF desktops. You said you had the MT or Mini Tower. I looked in the Dell manual and the specifications for both the MT and DT version shows no 30W GPU limit. Loking at photos I see the MB has 2- PCIe 16x slots maybe the 2nd one gets 30W which would kind of make sense if it's not for a GPU.

I just joined after reading this thread because I did this very thing. I bought a 790 Mt, upgraded the ram, installed an ssd, and an Evga 1050 ti SC.
I would strongly suggest that you upgrade your psu to anything that is affordable (evga 430w is like 30 bucks). My psu fried itself and took the motherboard with it. Luckily, 1155 mobos are cheap on ebay. However, I also had to get a new case due to Dell using proprietary connectors for the switch and leds.
Just a little cheap insurance. Otherwise it is a great gaming system.
Edit to add: Putting in a new psu will enable you to upgrade later to a more powerful card as most will require a 6 pin pci-e power line and almost all of the aftermarket psus come with them.

That's why I recommended the 1030. At 30W power usage, it's the closest thing you can get to onboard graphics in terms of low power draw and still be using a videocard. That makes it the best bet for not overloading a low power PSU.
A proper PSU is always the best choice, but if you don't have the money for one, then you don't have the money.
