Question Compatible components with Packard Bell iMedia S2190

[Sun_74]

So I have an AMD A4 6210 APU and am curious as to if I can add a GPU (Nvidia GeForce GTX 750-Ti) to it, I'ved looked at other threads on the internet that say you can but need a PCIe x16 slot, I don't know if I have one or not but I've seen that some people have a Nvidia GPU and and AMD A4 APU on User Benchmarks for the iMedia S2190 so I'm a bit stuck.

Also, I'm curious as to which other components are compatible with the S2190

So I've gotten around to cleaning my PC and while I cleaned it, I took the time to check the components, I've taken some photos below, it looks like I've got a spare PCIe x16 slot, only problem is the version of it since I don't have the manual from my 2014 purchase of the PC.
EDIT: I've added a closeup of some of the wires to the PSU

Typical slim size PC with little very upgradable due to the slim size and weak power supply.
Power supply: 220 W.
Chassis type: SFF

Looks like you can install a kit of two DDR3L-1600 memory.

GeForce GTX 750-Ti needs a 300 watt power supply.

So what GPU would you recomment me adding to the APU system? I was thinking of a GT 710 if a GTX 750-Ti was incompatible
EDIT: Yes, I know GT 710 needs 300Watts but it's designed for low power
