So the parts for my build are coming in today, however, in case my dad would like to add a video card, I'm looking for ideas. Build is as follows:

PCPartPicker part list / Price breakdown by merchant / Benchmarks

CPU: Intel Core i3-4330 3.5GHz Dual-Core Processor ($132.97 @ OutletPC)
Motherboard: MSI H81I Mini ITX LGA1150 Motherboard ($65.38 @ Newegg)
Memory: Kingston XMP Blu Red Series 8GB (2 x 4GB) DDR3-1600 Memory ($69.99 @ Newegg)
Storage: Crucial M500 120GB 2.5" Solid State Disk ($72.99 @ NCIX US)
Wireless Network Adapter: TP-Link TL-WN823N 802.11b/g/n USB 2.0 Wi-Fi Adapter ($12.99 @ Amazon)

partpicker says it tops out around 100w without a graphics cards. From my research, a Radeon HD 7750 has a max TDP of 55w, but a recommended power supply of 400w. Assuming it fits physically, which I'll check today when I do the build, do you think I would be alright, considering my power supply is only 250w max? I'll link the card I am considering, if you have any thoughts or other ideas, please feel free to share!

1> Less heat
2> Less electricity consumption
3> Goes through stringent testing under ATX specifications so voltage output and ripple are well controlled
4> Generally PSUs coming with a case dont provide the stated wattage, and if they do, not completely off the 12V rail.

The above parts were already purchased. I could swap the power supplies in the future if necessary, but I'd like to know your reasoning for why I'd need to switch to an 80+ rated power supply. Less heat?

a 250W PSU isn't enough for the 760, I suggest getting a 450W PSU.
The reason for 80+ Rated PSU is for putting basically, effeciency. A PSU may produce let's say for example 500W of Power, however let's say it's effeciency is 50%. This would be the PSU only produces 250W of usable energy while the other 250W is useless and is usually heat which is why low end PSU generate more heat than 80+ PSUs.
I suggest the XFX 450W PSU, however idk if this will work in your case. It's 80+ Rated and is more than enough to power the 760(if that aswell fits in the case)

Your main limitation isn't the PSU (despite it only have 16A on 12V) but the fact you only have a single expansion slot. 90%+ of modern graphics cards take up a dual slot, so you can immediately rule them out.
There is also no such thing as an ITX graphics card, just to be clear. The MSI is branded in this way, but there is no standard ITX requirements, so it's entirely a marketing term.

Funnily enough, the card you mentioned, the HD7750 does come in both low-profile and single slot form, which makes it ideal for builds like this, and it's absolutely fine as it requires no PCIe power cables. It'll be absolutely fine.

Also, the stuff people are saying about 80Plus and efficiency is mainly nonsense. It's simply an efficiency rating system, which has a side effect of generally increasing quality/manufacturing standards. A 500W rated PSU should provide 500W (though this is not always true for poor quality units), regardless of it's efficiency rating. The efficiency translates to how much power it draws from the wall above it's rated values.
