I'm not Jay, but here's my two cents:
1. I'd buy between 1000W and 1200W. It's not a problem to go higher, but, for reference, I use a 1200W with a 4090 and a R9 5900X and I have
never
seen it reach 700W. This is with a PCI-E RAID controller, 4 HDDs, water pump and a bunch of fans and lighting. Tipical system load reported by the PSU is 170W idle, 300W on light games and 600W on heavy games.
2. Most PC Brand PSUs are manufactured by others. My PSU is an ASUS ROG Thor 1200W, which is manufactured by Seasonic. The ASUS Loki is manufactured by Great Wall, who also makes mid range PSUs for Corsair. I'd look for PSUs from Seasonic, SilverStone or other brands as long as they are manufactured by a good OEM (I've seen good ones from...

I'd look for PSUs from Seasonic, SilverStone or other brands as long as they are manufactured by a good OEM (I've seen good ones from Seasonic, Enermax, FSP, Flextronics). Thermaltake's power delivery should be good too, I just feel the rest of their stuff feels cheap (although it's been a while since I've tried them).
3. I wouldn't worry about having to use an adapter, just secure it properly and it should be fine (I use it this way). Naturally, if you are buying a PSU now and have the opportunity to get one that's ATX 3.0 compliant that would be preferrable.
