NOTE: PowerEdge XE9680 system supports 5+1 PSU redundancy which means only one PSU is redundant. A/B Grid
Redundant setting in iDRAC is not supported.
NOTE: PowerEdge XE9680 system also supports 3+3 PSU redundancy. When two or more PSUs are down, this fault
tolerant redundant mode triggers GPU power brake and GPU clocks are throttled to one-fourth and GPU performance will
drop to around one-fifth.
NOTE: This system is also designed to connect to the IT power systems with a phase-to-phase voltage not exceeding 240
V.
NOTE: Heat dissipation is calculated using the PSU wattage rating.
NOTE: Do not mix PSUs from different vendors within a single system configuration to ensure optimal performance and
reliability.

PSU power cord
Form factor Output Power cord
Redundant 86 mm 2800 W AC C22/C21
Redundant 86 mm 3200 W AC APP 2006G1
NOTE: 2800W 54V PSU has a C22 input socket that requires C21 to C20 jumper cord to connect it to PDU in the rack.
Traditional high amperage power cords C20/C19 cannot be inserted into the PSU.
NOTE: When selecting or upgrading the system configuration, to ensure optimum power utilization, verify the system
power consumption with the Enterprise Infrastructure Planning Tool available at calc.
