HPE P44712-B21 Flexible Slot Titanium Hot-Plug Power Supply Kit

Overview

The HPE P44712-B21 is a Flexible Slot (FS), Titanium-efficiency, hot-plug power supply kit rated for the 1800W–2200W range. The Flexible Slot form factor is HPE's modular PSU architecture — a single bay accepts different wattage tiers and input-voltage configurations without chassis modification, which matters when you're standardizing spares across a mixed-density rack. Titanium efficiency (80 PLUS Titanium) sits at the top of the efficiency curve, reducing heat output and lowering operating costs in 24/7 datacenter and edge deployments. Hot-plug capability means P44712-B21 can be installed or swapped under live load — no planned downtime required, a practical requirement in any environment running continuous workloads. This is a kit SKU; confirm with HPE's compatibility matrix that the target server platform and input power feed (voltage/phase) align before ordering.

Compatibility

The P44712-B21 is designed for HPE ProLiant and Synergy servers that accept the Flexible Slot power supply form factor at the 1800W–2200W tier. Flexible Slot bays are present across multiple HPE Gen10 and Gen10 Plus platforms including select ProLiant DL360, DL380, DL560, DL580, and ML350 configurations, as well as Synergy frame infrastructure. Exact per-server compatibility depends on chassis revision, backplane, and IEC input feed — verify against the HPE Quick Specs or Server Memory and Option Compatibility Tool for the specific server model before procurement. Not compatible with non-Flexible-Slot HPE chassis or third-party server platforms.
