On a X570 Steel Legend Motherboard, is a power cable to the 4 pin 12V Power Connector (ATX12V2) necessary? I am using a Corsair RM750x, several years old, and they do not provide such a cable. I don't remember my X399 Taichi having such a requirement.

It does appear that the 4 pin connector is not needed. I don't know of any power supply that has that supports that cable.

most higher end psu's come with 2 x 4+4 power pins for 4 and 8 pin mobo headers .. if you start running into stability issues .. especially under full load .. then it would behoove you to get a better psu

It really depends on the CPU you use, something like a 3900x or 3950x would benefit
from the extra power/stability and lower heat that comes with using both the 8 and
4 pin connectors. Not using it means more current being pulled through the 8 pin
which in turn creates more heat on that power circuit. Regardless of needed or not
there is an actual benefit to connecting it, better efficiency and possibly less
heat around the connector and related components.
