Hey,

I want to buy an "B550 Steel Legend" for my Ryzen 3600.
I currently have an "be quiet! System Power 9 Cable Management 600W " power supply. Now I see that besides the 24 pin Power Connector the Steel Legend also has an 8+4 Power Connection, but my PSU can only have 2*4Pin Power Connectors.

So do I have to buy a new PSU to satisfy the 8+4 Power, or is it enough if I only put one 4 Pin or two 4 Pin Power Connectors into these ATX 12 V Power Ports?

No you don't need a new PSU, that extra 4pin is meant to just provide additional power, but depending on the board design it might not be doing anything at all. I'm of the same mind as Buildzoid here, manufacturers don't need to add that extra 4pin.
