MSI MPG A850G is  enough for this combo.

I recommend the Corsair RM850e 2023.

I love my ASUS TUF Gaming 1000W Gold PSU.

Given the power draw of a 14700K and RX 7900 GRE, especially if you plan to overclock them, I suggest a PSU of at least 850W, or 1000W to be safe.

My recommendation would be the be quiet! Dark Power 12 with 850W or 1000W. It's a premium PSU line with exceptional performance, silent operation, a 10-year warranty, and full modularity. The 80+ Titanium efficiency will reduce heat output and fan noise.

Alternatively, for a more budget-friendly pick that still offers great quality, consider the Corsair RM850x or RM1000x. These are fully modular 80+ Gold PSUs with a 10-year warranty.

Yes, I also use it for my RTX 4070 Ti SUPER.

A 850W to 1000W PSU is enough.

Corsair RMx Series (2021) RM850x.

750W PSU can handle this build.
