Title says it all, I've tested it on UserBenchmark and I've tried playing a few games on it, they all end up shutting down when under load for too long, however UserBenchmark shuts down as soon as the graphics test begins.
Here are my specs:
CPU: Ryzen 5 2400G
CPU Cooler: Noctua NH-L9a chromax.Black
GPU: AMD Vega 11
Motherboard: ASUS ROG B450-I
RAM: 16Gb HyperX Fury @2666mHz
PSU: 150W PSU (case is small so it came with a small PSU)

The PSU just came with the case, which is a Realan E-H60. Sorry for the confusion, I would've given a specific model or brand if I could see one
There's a big problem here; this "150W" PSU isn't actually a 150W PSU in any real sense, at least according to the specs of the 150W PSU included in this mini-case.

There's only 8A of power available on the +12V rail meaning that, for any PC built since the Pentium III, this is somewhere around a 96W PSU in real-world terms. That's not enough for a 2200G at high graphics load.

Hmm so I'm assuming the best course of action would be to replace the PSU, but I'm not sure what form factor that it would be considered as.

The one you picked is cheapie Alibaba-type stuff. It might have been fine if you were just using it as a HTPC and weren't really taxing it or if you had gone with a 2200G.

Something like this would be far better.

Honestly, for long-term use, you're far better off with a proper mini-ITX case and a SF PSU.

I figured that the PSU may have been the problem, and the reason I went with the case was because I got a good deal on it, but now I see why lol. I have been looking at this as a replacement, and I'm sure it'll do the trick but I could be wrong: https://www.ebay.com/itm/12V-180W-DC-Pico-ATX-switch-PSU-with-Power-Adapter-Car-Auto-MINI-ITX-Power/263087650726?hash=item3d413ef7a6:g:Ac8AAOSwc-tY5RWk

It doesn't. Again, you have to look at the +12V power.

"4).Output current +12V: 8.5A Max Load(15A Peak Load)"

Peak load isn't a real spec; it's what people selling cheap Chinese junk power supplies stick in to trick people. 8.5A means that you have 102W of +12V power. That is, if you believe their specs are accurate, not a given since junk PSUs commonly come with completely made-up specs.

The problem is you're looking for a cheap Alibaba solution for crucial safety equipment. You get pretty much what you pay for.
