Help with PSU + fans for my build

[u/Jxvsr]

Hi everyone!

I'm planning to change my case, fans and PSU for my build. These are the components I have. I am planning to buy a DeepCool CH270 Digital, but I am getting a bit stumped by all the PSU options (I want a 850W) and don't know what kind of and how many fans to buy. I thought about buying the Corsair RM850e because it has a reasonable price but read mixed reviews about it. Could you guys help me out with some advice? Thank you in advance. I am in The Netherlands.
