Home Networking Servers & Storage HPE 748287-B21 1200W Common Slot Platinum Hot Plug Power Supply

HPE 748287-B21 1200W Common Slot Platinum Hot Plug Power Supply

Brand:
HPE

The HPE 748287-B21 is a 1200W Common Slot Platinum Hot Plug Power Supply designed for supported HPE server and infrastructure platforms. It delivers up to 1200W at high-line input, with a 100–240V AC input range and 50–60Hz operating frequency. Its hot-plug design supports faster serviceability, while the Platinum efficiency class helps data-center teams manage power consumption and operating costs.

OVERVIEW

  • The HPE 748287-B21 is a 1200W Common Slot Platinum Hot Plug Power Supply for supported HPE server platforms, positioned within HPE's Common Slot power portfolio. Compatibility: verify the exact HPE server/chassis and power configuration. Compared with 739254-B21: 748287-B21 provides up to 1200W at high-line input, while 739254-B21 is a 750W Platinum model.

USE CASES

  • Enterprise server power expansion – Adds substantial power capacity to supported HPE systems for demanding processor, memory and storage configurations.
  • Redundant PSU deployments – Hot-plug capability makes it suitable for supported multi-PSU configurations where service continuity is important.
  • Data-center server upgrades – Provides a documented HPE option for increasing available power capacity without replacing the entire server.
  • High-density compute environments – The 1200W high-line rating supports power-hungry server configurations within compatible HPE platforms.
  • Server lifecycle extension – Useful when existing HPE infrastructure needs a replacement or higher-capacity power module.
  • Power-efficiency initiatives – Platinum-class efficiency helps organizations target lower conversion losses and improved data-center power economics.
  • Infrastructure standardization – Common Slot architecture can simplify PSU sourcing across compatible HPE equipment.
  • Field-service replacement – The hot-plug form factor supports faster replacement in platforms designed for hot-plug PSU servicing.

KEY FEATURES

  • 1200W Maximum Output – Provides high power capacity for compatible HPE server configurations.
  • Common Slot Design – Uses input-voltage, frequency, output-rating, power-factor and part-number specifications for 748287-B21. HPE Common Slot architecture for supported platforms.
  • Platinum Efficiency – Helps reduce energy losses and operating costs compared with less-efficient power supplies.
  • Hot-Plug Capability – Allows replacement without shutting down the server when the platform supports redundant hot-plug operation.
  • 100–240V AC Input – Supports a broad AC input-voltage range for data-center deployments.
  • 50–60Hz Frequency – Supports standard AC power frequencies used in enterprise facilities.
  • 0.998 Power Factor – Provides a high specified power factor for efficient facility power utilization. 
  • OEM HPE Option Number – 748287-B21 simplifies procurement, replacement and configuration matching.
  • Multiple High-Line Input Ratings – Delivers up to 1200W at 200–240V nominal input, supporting higher-power server configurations.
