Question Will My PC Work With a Vega 56 GPU?

[KKEGAMING]

I currently have a pc with:
APU: Ryzen 5 3400g
RAM: 2x8GB 2666mhz
MB: Gigabyte GA-A320M-H (Rev 2, I think) PSU: Cooler Master MWE 500 230V
Case: CiT Seven MATX
I'd just like to double check I could be able to use this GPU if I buy one second hand?
