your CPU and mobo are assuredly very fine and will not throttle that new GPU. just buy a nice modular platinum-rated PSU that will cover you for the next 5-10 years. it's a worthy investment, just as worthy as buying your dream case or that fancy motherboard with three gens of life expectancy.
it's not unusual to have to buy a new PSU to deal with a graphics card, especially the monsters out nowadays with very demanding single-rail voltages. it's an extra $200 expense, which isn't the biggest deal. especially in comparison to buying an entirely new PC.
using your current PC with a 12-core ryzen and an overclocking-level motherboard or whatever as a media HTPC is just such a stupid idea. you can put together a media streaming machine for $300.
