I'm not looking to build a completely new PC right now because component prices are high. My current system has an i7-4790, 16GB of DDR3 memory, and a 1TB SSD. I mainly play RuneScape, Project Zomboid, and Skyrim, so I don't need a high-end gaming card. I was considering an RX 6400, but used models are difficult to find. The PC has a proprietary power supply, although I also have a spare 400W PSU. Ideally, I'd like to spend around $100 or less. What graphics card would pair well with this system?

Because the system uses a proprietary power supply, a card that runs entirely from the motherboard is the safest option. A GTX 1650 4GB is probably the most practical choice, provided it fits the case. The RX 6400 is also low-power, but it uses a PCIe x4 connection and can lose performance on an older PCIe 3.0 system. Avoid powering the GPU from a separate PSU unless you know exactly how to synchronize and ground both supplies; replacing the proprietary unit or using a properly compatible PSU is safer.
I found a GTX 1650 4GB listed for about $90. Would that be a reasonable price?
The i7-4790 will limit newer or faster graphics cards in some games, but that doesn’t make a modest upgrade pointless. For RuneScape, Project Zomboid, and Skyrim, a GTX 1650-class card should be enough. A complete used budget system or an AM4 upgrade could be better value eventually, but it’s understandable not to replace the whole PC while prices are high.
Exactly—I know a newer build would be better, but I’m trying to keep this machine going without spending much.
If you can find one cheaply and your power supply and case support it, a GTX 1080 or 980 Ti would offer much more performance. However, those cards use considerably more power and may be overkill for your games, so they aren’t ideal with a proprietary office-PC power supply. A GTX 1650 is a better match for a simple, low-risk upgrade.
A used GTX 1650 around $90 is reasonable if it’s in good condition, includes the correct outputs, and fits your case. Check whether it’s the standard model or a lower-clocked variant, and make sure it doesn’t require a six-pin connector if your current power supply can’t provide one. It should handle your listed games well at 1080p.
That makes sense. I’ll probably keep looking for a GTX 1650 rather than trying to run two power supplies together.
