The HP 312257-001 is a 48-watt 12V voltage regulator module (VRM) designed for server and enterprise computing applications. This compact module delivers regulated 12V DC output from higher-voltage input sources, providing stable power distribution to processor cores, memory, and other critical server components. The 48-watt capacity supports moderate to mid-range power demands typical of single or dual-socket server architectures from HP/HPE's ProLiant line. The VRM integrates multiple voltage phases and thermal management to maintain operating efficiency under variable loads. Compatible with HP ProLiant DL360, DL380, and similar generation servers that utilize modular power delivery architectures. Typical applications include datacenter server builds, enterprise compute infrastructure, and system upgrades requiring reliable core voltage distribution.
