I have a ryzen 3 3200g, gtx 1080 3gb, 16gb 3600mhz from Corsair, asrock b450m pro4 mini atx motherboard, and a Corsair 450 watt bronze psu. I am currently it the upgrading stage and have just upgraded my ram and bought an aio. I want to upgrade my graphics card next. I understand the bottlenecking of the 3200g on a rtx 2060 but am more interested in the straight upgrade now. Later I am planning to upgrade my cpu. I would like to know if 450 watts is enough for a rtx 2060.
