Pro Disk Network Buyer’s Guide: Power Supplies & Power Protection
PSU Sizing: Connected Load, Efficiency Curves, and N+1 Redundancy
Sizing the 331-4606 or its replacement starts with calculating connected load. Add up the nameplate wattage of CPUs, GPUs, drives, fans, and add-in cards under maximum sustained load. Idle is irrelevant; peak sustained is what matters. Size the PSU at 60-80% of nameplate load for best efficiency — modern Platinum/Titanium PSUs hit peak efficiency at 50% load and degrade above 80%.
AC Input, Phase Balancing, and Datacentre Power Best Practices
For UPS-fed servers, confirm the UPS output waveform is compatible with the 331-4606's input. Modern PSUs accept both sine-wave and high-quality simulated sine-wave inputs, but older or stepped-approximation UPS outputs can cause buzzing or premature PSU failure. When in doubt, use double-conversion online UPS units.
