Computer PSUs are generally more efficient at european electical standards. I read many a thread two years ago about cryptominers in America wiring our heavy appliance 220v lines into their racks to approach the efficiency that PSUs can reach at higher volts.
And of course some datacenters just wire DC to the whole schebang instead of having an individual, well two redundant, PSUs per server.
