I'm looking to add a dedicated GPU to my existing PC setup, and I need some suggestions. Here are my specs: I have an AMD Ryzen 3 3200G CPU, 16GB DDR4 RAM, and a 512GB NVMe storage. My motherboard is a Gigabyte AM4, and I currently have a 500W PSU, which doesn't have an 8-pin PCIe connector.
The goal is to find a GPU that can run off the PCIe slot alone or potentially use an adapter, as I'd prefer not to replace the PSU if possible. I'm not aiming for high-end gaming—just something that can handle Minecraft and some older games from the PS3 and early PS4 era, like Mortal Kombat 9 and the War for Cybertron games. I'm only looking for 1080p performance and plan to buy used in the UK, mainly from CeX and Facebook Marketplace. What card would you recommend that meets these criteria?

If you're not against getting a used GPU, check for cards like the GTX 1650 since they generally perform well without needing additional power connectors. Just be cautious with older PSUs, as running a new GPU may push the limits.
Just a heads up about your PSU: A 500W unit without a PCI-E power connector likely isn't top-notch. It could be from a workstation or pretty old. I'd recommend looking into replacing it, as running a GPU off a low-quality PSU might lead to stability issues.
You might want to consider a used low-profile GTX 1650. It should fit well in your setup, and they don’t require external power. Just double-check if there's a price difference compared to the full-sized version if your case can accommodate it.
The RTX 3050 with 6GB would be your best choice since it doesn’t need any extra power connectors. It’ll perform well for 1080p gaming and supports DLSS, which is great for newer titles like Fortnite.
