A:Answer At bear minimum yes I tested it on a 550watt psu, as long as you have a decent power supply from a reputable company and do not overload your system with power draw, Asus states 650watt min but that's on an overclocked pc set up where both CPU and Graphics are overclocked but if your system is running on Nvme and is not running lots of high draw accessories then 550 watts will work, I'd recommend 650watts at min for that card, but a 850watt or better for future headroom for upgradability better (even a 1000watt PSU would work as well, a 1000watt psu will only use the power it needs and not the full 100watt consistently), but 550watt psu would work
