A minor point here. There is no such thing as DDR5. GDDR5, yes. Graphics memory has different generations from mainboard memory. I know this is picky, but it can make things confusing some times.
You will need a power supply with the correct PCIe connectors to power whatever graphics card you get. It's not just the total wattage, it's having the correct PCIe 6-pin or 8-pin connectors for the card.
