Will this work?

I'm going to get a RX 6600 and I've googled it but just wanted to make sure if it worked with my PSU. https://www.bequiet.com/en/powersupply/1549

It may work but the minimum recommended specifications state that your PSU should be 450w. I would advise against trying to use an underpowered PSU as you could experience errors very quickly, with a small possibility of physical damage.
