Question PSU recommendation regarding RTX 4070 Ti Super

[Sir_My_Cocaine]

Hello to everyone! (new member here, and sorry in advance for my lack of technical terms - I don't know much about electricity)

I bought an ASUS RTX 4070 TI Super. My PSU is Antec 850W (bought it in 2016).

The cable that came with the 4070 has two 8pins.

The PSU has two separate PCIe (6+2) 8 pin cables that fit into these:

And the Antec 850W PSU has these available ports:

My question is, is it safe for me to plug the two PCIe (6+2) cables into one of these 12v ports, one next to the other? Does it matter which 12V port I use? Do you think I need to buy a new PSU or can I use my holy relic from 2016?

I thank you for all your help in advance!

Welcome to the forums, newcomer!

My PSU is Antec 850W (bought it in 2016).
Antec is the brand of the unit, while 850W is the advertised wattage of the unit, what is the model of the unit?
