Pro Disk Network Buyer’s Guide: Power Supplies
PSU Sizing: Connected Load, Efficiency Curves, and N+1 Redundancy
For N+1 redundancy in a dual-PSU server, both PSUs must be rated to handle full load alone. This is non-negotiable in production: if a single PSU fails and the surviving one is undersized, the system shuts down. The PWR-4450-POE-AC should be matched in wattage rating to the partner PSU in the chassis; mismatched ratings sometimes work but trigger warnings in the BMC.
AC Input, Phase Balancing, and Datacentre Power Best Practices
Document the PWR-4450-POE-AC model, wattage, and partner PSU in your CMDB. Power audits typically find one or two undersized servers and one or two over-redundant clusters per rack — both of which waste capacity that could feed additional production load.
