HPE Synergy 12000F 2650W AC TI PS - 798095-B21

HPE 798095-B21 2650W High-Output AC Power Supply for Synergy 12000F

Overview

The HPE 798095-B21 is a 2650W high-output AC power supply engineered specifically for the HPE Synergy 12000F composable infrastructure chassis. If you are provisioning or expanding a Synergy 12000F frame and need a power supply that can sustain dense compute and storage blade configurations without throttling, this unit is the verified fit. It accepts 200V–240V AC input — meaning it is designed for data center-grade PDU circuits, not standard 120V branch circuits. Plan your PDU and circuit allocation accordingly before ordering.

At 96% efficiency, the 798095-B21 converts nearly all input power directly into usable DC output, shedding very little as heat. In a high-density chassis environment where dozens of blades and fabric interconnects are drawing simultaneously, that 4% loss delta versus a lower-efficiency alternative adds up fast — both in cooling load and operating cost over a multi-year deployment. For a 2650W unit, a 96% efficiency rating means roughly 106W dissipated as heat rather than the 265W you would see from a 90%-rated alternative — a meaningful difference for precision cooling designs.

Key Features

• 2650W Continuous Output: Delivers sustained power capacity for fully populated Synergy 12000F frames running mixed compute and storage blade configurations. This is the high-output variant — sized for dense workloads where lower-wattage supplies would force load-shedding or throttling under peak draw.
• 96% Conversion Efficiency: Near-titanium-class efficiency keeps heat rejection low and reduces per-unit energy cost. Over a three-year operating window, the efficiency delta versus an 85–90% supply at this wattage translates to hundreds of kilowatt-hours saved per unit — worth calculating against your PUE targets before choosing an alternative.
• 200V–240V AC Input Range: Designed exclusively for high-voltage data center circuits. Paired correctly with 208V or 230V PDUs, it draws less current for the same wattage output compared to a 120V supply, which reduces conductor sizing requirements and PDU port loading. Confirm your PDU voltage range before provisioning.
• High-Output Power Supply Type: The 798095-B21 is classified as a high-output unit within the Synergy 12000F power supply family — intended for maximum-density blade populations. If your frame is lightly loaded or you are deploying fewer blades, a lower-wattage Synergy 12000F supply may be a more cost-appropriate fit. Match the supply to your actual chassis bill of materials to avoid over-provisioning.
• Chassis-Specific Design: Built for the Synergy 12000F frame only. The Synergy composable architecture uses proprietary mid-plane connections and power management firmware integration — do not attempt to cross-fit this supply into other HPE chassis families. Compatibility is frame-specific by design.
• Hot-Plug Capable (Architecture-Supported): HPE Synergy chassis power supplies are architected for hot-plug replacement within a redundant configuration, allowing failed unit swaps without frame downtime when installed alongside a second supply in a redundant pairing. Verify your frame's redundancy configuration before assuming non-disruptive replacement.

Integration and Compatibility

The 798095-B21 is qualified exclusively for the HPE Synergy 12000F frame. HPE Synergy composable infrastructure is a closed, validated ecosystem — using non-HPE or non-validated power supplies voids HPE's frame support and may prevent proper HPE OneView power management telemetry. If you are integrating this supply into an existing Synergy deployment, confirm your frame's current power supply population and redundancy mode in HPE OneView before adding or swapping units. For new frame builds, consult HPE's Synergy 12000F QuickSpecs for the supported supply count per frame and per-slot power budgets. Buyers integrating Synergy frames into broader data center and server infrastructure deployments should cross-reference the chassis power budget against total blade and interconnect draw before finalizing supply count.

Frequently Asked Questions

Q: What chassis is the HPE 798095-B21 compatible with?

A: The 798095-B21 is designed for the HPE Synergy 12000F composable infrastructure chassis. It is not rated for use in other HPE chassis families.

Q: What input voltage does the 798095-B21 require?

A: The 798095-B21 requires 200V–240V AC input. It is intended for data center-grade PDUs and high-voltage circuits — not standard 120V branch circuits.

Q: What is the power output of the 798095-B21?

A: The 798095-B21 delivers 2650W of continuous output power, making it the high-output variant in the Synergy 12000F power supply family for dense blade configurations.

Q: What efficiency rating does the 798095-B21 carry?

A: The 798095-B21 is rated at 96% efficiency, meaning very little input power is lost as heat — an important factor in high-density chassis deployments where cooling load directly affects operating cost.

Q: Is the 798095-B21 (also searched as 798095 B21) hot-pluggable?

A: HPE Synergy chassis power supplies support hot-plug replacement within a redundant power configuration. Verify your frame's redundancy mode in HPE OneView before performing a live swap.

Ted Perry

The 798095-B21 is a purpose-built supply for the Synergy 12000F frame, and the spec that matters most in a dense chassis deployment is that 96% efficiency rating at 2650W output. At that wattage, the difference between 96% and a lower-tier 90% supply is roughly 159W additional heat rejection per unit — and in a fully populated multi-frame rack, that thermal delta is not trivial to absorb.

Technical Highlights:

• 2650W High-Output Rating: Sized for fully populated Synergy 12000F frames — if your blade count is low, a lower-wattage supply may reduce upfront cost without sacrificing headroom.
• 96% Efficiency: At this wattage tier, 96% efficiency is near the top of what AC power supplies deliver — meaningful for both PUE calculations and long-term energy budgets in 24/7 data center environments.
• 200V–240V AC Input: Designed for high-voltage data center PDUs; lower per-amp draw at 208V/230V reduces PDU port loading compared to equivalent 120V supplies, enabling higher per-rack density.

Deployment Considerations:

• Confirm your site's PDU voltage range is 200V–240V AC before ordering — this supply will not operate correctly on standard 120V North American branch circuits.
• This is a chassis-specific part; do not cross-fit into other HPE frame families. Verify the exact Synergy 12000F power supply slot requirements in HPE OneView or the frame QuickSpecs before purchasing multiple units.

For data center architects provisioning fully loaded HPE Synergy 12000F frames in high-density colocation or on-premises environments, the 798095-B21 is the correct high-output supply to specify — provided your PDU infrastructure is already 200V–240V AC qualified.
