This needs to be confirmed by thermaltake that the 12vhpwr connection on the 850w gf3 is 300w, the 1000w gf3 is 450w, 1200w (or higher) gf3 for 600w?

I just bought 1000w and it came with 450w cable. someone needs to get their act together over at thermaltake and put out a sheet with correct info.

What power supply upgrade will fit in my hp elite 8300 sff desktop?

no, not even remotely close. do not put a psu like this intio any OEM machine. you will have problems because OEMs like HP and dell use crap proprietary parts that may not work correctly with something like this. or even connect at all. Use this to build a real pc and ditch that HP thing.

Do i need an adapter for the rtx 3070?

Hello, no you would not need an adapter.
