You have more than enough room. This build will only draw 250-300 watts.

Its plenty of power. PCPP always over estimates. You would be lucky to break the 300W mark.

probably not. Leave at least 100 watts of head room. Go with a 650 watt psu if you want to be safe.

It’s more than enough. PCPP calculator way overestimate wattage requirements. It’ll draw more like 250-300 watts under heavy loads.

As for the 100 watt headroom, a good PSU can handle any load 24/7 without fault within its warranty period. So unless your build is truely drawing 400 watts on a 450 watt PSU and you intend to overclock, then yes, up it to a 550 watt.

Yeah im getting a 240mm radiator for CPU cooler and considering that ill probably overclock so ill probably bump it up. thx for response!

Actually, since your build only draws around 300 watts and that Ryzen is efficient, you still won’t need more than a 450 unit.

A 240mm AIO would actually be a waste as Ryzen is limited by its architecture, not thermals. A Cryorig H7 can achieve the same clocks as the AIO, and the H7 is 30-40$.

650W is just a waste of money (if it's more expensive than 550w or 450w).

Zero need to go above 550w.

First of all thx for responding! So I absolutely agree with you about the memory and all the other Stuff but with the memory I actually had that exact memory selected on my build but then found out the one i had selected was made for intel platforms so a further investigated checked the SKU to make sure i had the same one made for intel platform and i did then found out they a exact copy of it except for AMD platforms so i went looking for it but could not find a model with the same SKU! so thats why i switched to corsairs because they do the same thing one for intel platforms and 1 for amd platforms and was able to find the model for AMD (idk if i just couldn't find it or what ill look again)

So sorry i am actually incorrect i am talking about the RGB version so the one you selected is compatible? (side note do you know how much storage the OS takes up?)
