Also monitor your cpu and gpu temps to make sure they aren’t too high. For a power supply you want a decent one. The manufacturers have their budget lines and good lines, so you want to try to get a good one. Check this thread out.

There should be a psu tier list around someplace(on my phone atm). Personally I’ve got a Corsair rmx 850 Modular that I like, but my needs may be different than what yours are. But if you think you’ll upgrade later it may be good to buy up if you can. For example I’ve got a gtx 1060 3gb card installed now, but I’ve got an rx 6700xt on the way.
