I just bought a 2nd hand GPU (AMD RX 570, 2017) and 8GB of DDR3 RAM to make my parents' computer last longer (upgrading it to 16GB). I also need a new PSU and I think I've found the right one. I'm going for 650W.
I don't get any interactions at all in here, but if you read me, do you have any recommendations? I can give some more specs if needed.
