Build recommendation 7700X

Hello everyone, im planning to get some parts for a new build on amazon prime deals since they look hella cheap. Im getting cpu,mb and psu for now will get the gpu later, ( prolly 9070xt)

The question is which mb and psu should i go for?

Ive got my eyes set on ryzen7 7700x for 200 usd

MB options are
Gigabyte B850 aorus elite vs gigabyte x870 Eagle

PSU
Thermaltake toughpower gt 850 vs msi mag a850 pcie5

I got very little knowledge on pc parts please for those who know advice

P.S is choosing parts by asking Chatgpt a good idea or should i stop doing that lol
