Good budget option

Max Output Power: 850W

Runs very very quiet.
Paired with an i7-12700k and rx7800xt with a little more overhead incase it is needed in the future.

Read the cybernetics report and this was a winner over cooler master options in the same price point for noise & heat generation alone.

Brilliant!

Nice black cables, fully modular. Went in super easy! Cables had enough length to make it easy to install but not so much that cable management was tricky!!

Decent PSU but not the quietest

Max Output Power: 850W

Basic PSU that does the job, my biggest gripe with it is the noise - may want to avoid this for any silent setup.

Cannot fault it for the price

Max Output Power: 850W

Runs super quiet, I had a 2yo 600W PSU previously and that thing you could hear through the case, this MSI PSU also has the new 12V power supply cable for the new 40 series GPUs and comes with yellow markings to indicate it has been plugged in correctly, worked out of the box with a Gigabyte Gaming OC 4080 Super, Ryzen 9 CPU and plenty of overclock on CPU, GPU and RAM, not much more I can say.
