Hi, I have a Corsair TX650M in my build that I bought recently because my last PSU failed. I saw it had really good ratings and the 650 watts is plenty for my current specs. However, I am thinking of upgrading my RX480 to either a Vega 56 or 64. I'm just wondering if it is wise to attempt to run a Vega card on a wattage that is lower than what AMD recommends. AMD recommends 750w but I'm unsure if it is completely necessary as I know my PSU is pretty high quality despite the slightly lower wattage. I just don't want to waste money upgrading the PSU again if I don't have to. I don't really know much about PSU specs so I just wanted to be sure. Also it's probably worth mentioning I'm running a Ryzen 7 2700x stock as well.

Any advice is appreciated, thanks.
