Would that graphics card be able to operate with my current power supply (220 W)? I did a little research on it during the 2 days I was gone, and my research told me that the recommended power supply for it would be around 350-400 W, give or take. I would upgrade my PSU if I could, but it's specifically designed for my PC (my PC is a mini-tower, so only really small PSUs can fit). Also, would the graphics card fit inside my PC, since it is a mini tower?
