Good price shouldn't be in your vocabulary for power supplies right now tbh. They have blown up in price in the pandemic. Surprisingly psu is really the only thing the pandemic made expensive. Super Flower power supplies are really nice, nice enough to come with ten year warranties. I haven't read any reviews of their new Leadex III line, but they're known for putting out nothing but great units so if it comes with their standard 10 year warranty I'd buy it. Another really good series is Corsair RM. If you buy Corsair though it absolutely has to be an RM series with the level of components you have, as Corsair slaps their name on a lot of cheap too. Power supply shopping can be a real minefield though. For instance, EVGA used to have some really nice power supplies (namely the ones made by Super Flower that EVGA slapped their name on), but they have a lot of crap they sell under the EVGA name too. Seasonic used to be universally awesome and their high end still is, but even they make a few really crappy power supplies so you can't fully trust that name.
Also the Corsair AX line are really good too, but super expensive and were really designed for people running overclocked cpu plus four gpu back when SLI actually worked worth a .
