750W.
It's an EVGA G3 750 PSU, which I've only owned since the Black Friday week sales. I bought it partly due to it being necessary to be able to power the new GPU I bought around the same time - Vega 56 - as my previous PSU (Corsair VX450W, a model which had the reputation of being able to output 550W in a jonnyguru PSU test if I recall correctly) didn't have the correct connectors to do so.
Another reason for doing so however, was in anticipation of moving to a Ryzen 2 build when it gets released, and I thought that since my previous one was almost 9.5 years old, it made sense to get something more up-to-date anyway.
