: This resistor often burns out when the standby IC shorts, acting as a secondary fuse for that sub-circuit.
The schematic top clearly separates from N (power ground) . They are usually connected at a single point (star ground) on the PCB, but shorting them randomly invites noise into the gate drive circuits. ps42419ha schematic top

80 PLUS Verification and Testing Report. TYPICAL EFFICIENCY (50% Load): 90.51% AVERAGE EFFICIENCY : 88.83% 80 PLUS COMPLIANT: YES.
: The most common point of failure for "missing standby voltage." It is the primary controller for the standby rail.
