NZXT C850 PSU (2022) - PA-8G1BB-US - 850 Watt PSU - 80+ Gold Certified - Fully Modular - Sleeved Cables - ATX Gaming Power Supply

Will it work with an RTX 3070?

ATX 3.0?

Will this power supply be okay if i use a 24 pin and dual 8 pin lian li strimer plus v2 cables?

For this 850w psu, will it work for my desktop which only requires 500w power? (just to make sure that the 850w psu will not do damage to other parts)
