Can’t say I’ve used that power supply but a review of the 1350 watt seemed to suggest that model was good. I don’t know if they have it available but personally I like the Corsair rmx modular power supplies.
I’m being a bit nit picky but you may consider going for a smaller ssd for your boot drive. Even a 500gb. Then drop the spinning hard drive from you build and add a second larger ssd for your games.
Personally in my custom build (a few years old though), I’ve got a 240gb nvme ssd, 2 sata 1tb ssd drives, and one 2tb sata ssd. I’m splitting hairs but I do like the load times. Just when you install stream games or other programs you have to specify. Although it is nice when you need to reformat your OS drive, to reinstall steam, then when you install a game to just point it to where the game was originally installed and you don’t have to redownload the game. Which is nice if you don’t have a fast connection.
