the work station cards also run on 300 watts and looks like the 4090 goes to 450.

so you are getting a better practical card for the price

if you are making a mining type rig, then yeah, the extra price is wasting money.

but if you wanted to build a normal machine, the workstation cards are the most reasonable choice for anything more than 2 gpus

I find it challenging to get my 4090s to consume more than 300 watts. There are also a lot of articles, benchmarks, etc around showing you can dramatically limit power while reducing perf by insignificant mounts (single digit %).
