Right Mobo for PSU

[TheRCMGuy]

so i just gotten my CM MWE 550W 80+ PSU and was looking through both the PSU manual and mobo manual (b450 pro gaming carbon ac), and notice that whilst the 24-pin connector doesn't have a pin in the ~20th slot, the manual for the mobo say that should be a 'Res' pin on the connector. Will the mobo still operate without said pin when plugged and power or will I have to spend for a different psu/mobo?

RES = Reserved = not used.

There isn't a pin there. RES would mean reserved. You could also see N/C, which would mean not connected (and therefore not necessary).
