Opinions on this proposed CAD workstation, please

[woodson75]

Workstation to run dedicated CAD software, including but not necessarily limited to ArchiCAD and Artlantis.

Here is my partpicker list: https://nz.pcpartpicker.com/user/woodson/saved/Px84CJ

I'm wondering whether the PSU is maybe a bit too much? Would a lower wattage model do?

Thanks for your opinions.

Right at the top of PCpartpicker it says that config is using 274 Watts.
To be future proof safe I try to select around double that. 548W
550W should be enough.

Thanks for the tip! Any advice on a PSU that can handle my components (i.e. 1 x SSD, 2 x HDD, 1 x Optical and the Quadro P1000 GPU) from a connectivity point of view?

PSU's are not my field of expertise (I'm tired of being called an idiot).
The "experts" usually suggest Seasonic or Corsair.
