The one I currently have is a 450 watt psu and I recently upgraded from a rx 580 to a 6650 xt. My pc has a ryzen 7 5700x, 1 1tb ssd and 1 1tb hdd, stock cpu cooler and 2 phanteks fans, and 24 gb of ram, 2400mhz (asking because my computer seems to be running slower) also when I load games, my new gpu only uses about 50-60 watts but has a higher gpu usage % compared to my old rx 580 which would average 80-90 watts (I also have a b350m bazooka motherboard)
