HPE DL385 G11 12P PCIE GPU PWR CBL - P82106-B21

HPE P82106-B21 12-Port PCIe GPU Power Cable for ProLiant DL385 Gen11

Overview

The HPE P82106-B21 is the 12-port PCIe GPU power cable designed for the HPE ProLiant DL385 Gen11 server platform. If you are expanding GPU capacity in a DL385 G11 — for AI inference workloads, HPC, or GPU-accelerated applications — this cable provides the internal PCIe power routing required to support that configuration. Without the correct power cable in place, GPU cards in PCIe slots will either fail to initialize or throttle under load; the P82106-B21 addresses that gap specifically for the DL385 G11 chassis.

Sourced factory-new from the manufacturer supply chain, this is a genuine HPE component — not a grey-market substitute. At 0.59 lb, it is a lightweight internal cable assembly designed to route cleanly within the DL385 G11 chassis without obstructing airflow paths.

Key Features

• PCIe Interface: Engineered specifically for the PCIe power delivery path within the DL385 Gen11 — using the correct interface cable matters for stable GPU operation under sustained compute loads, not just initial boot.
• 12-Port Configuration: The 12-port layout supports multi-GPU deployments in the DL385 G11 chassis, making this the appropriate choice when the server is configured with multiple GPU accelerators rather than a single-card setup.
• Chassis-Specific Design: HPE platform cables are dimensioned and connector-keyed for the target chassis. Using a generic or cross-model substitute risks connector incompatibility or insufficient power headroom — this part is matched to the DL385 G11 bill of materials.
• Lightweight Assembly (0.59 lb): The low cable mass keeps installation straightforward and reduces strain on PCIe power connectors during chassis vibration in rack environments.

Integration & Compatibility

The P82106-B21 (often searched as P82106 B21) is designed for use in the HPE ProLiant DL385 Gen11 server. Confirm your chassis generation before ordering — DL385 Gen10 and Gen10 Plus use different power cable assemblies and are not interchangeable. If you are configuring a DL385 G11 for GPU-accelerated workloads alongside network infrastructure or HPE server platforms, verify the complete GPU option kit BOM from HPE to ensure all required cables, risers, and power components are included. For broader HPE ProLiant accessories and components, review the full HPE catalog to confirm complementary part numbers for your build.

Frequently Asked Questions

Q: Which server is the P82106-B21 designed for?

A: The P82106-B21 is designed for the HPE ProLiant DL385 Gen11 (G11) server. It is not confirmed compatible with prior DL385 generations.

Q: What interface does the P82106-B21 use?

A: The P82106-B21 uses a PCIe interface for internal GPU power routing within the DL385 Gen11 chassis.

Q: How much does the P82106-B21 weigh?

A: The P82106-B21 weighs 0.59 lb, making it a lightweight internal cable assembly.

Q: Is the P82106-B21 a genuine HPE component?

A: Yes. This is a factory-new, genuine HPE component sourced through the manufacturer supply chain — not a grey-market or parallel-import substitute.

Q: Can the P82106-B21 be used in a DL385 Gen10 server?

A: The P82106-B21 is specified for the DL385 Gen11. HPE platform cables are chassis-generation specific; compatibility with Gen10 or Gen10 Plus is not confirmed and should not be assumed.

Jerry Tildsen

The P82106-B21 is a chassis-specific internal power cable — the kind of part that gets overlooked until a GPU fails to enumerate at POST. It routes PCIe power to the GPU slots in the DL385 Gen11, and its 12-port configuration tells you this cable is meant for dense multi-GPU builds, not a single-card test bench.

Technical Highlights:

• PCIe Interface: Matches the DL385 Gen11 internal power architecture — the correct interface ensures the GPU receives stable power delivery rather than relying on a mismatched adapter with unknown headroom.
• 12-Port Layout: Supports multi-accelerator deployments within the DL385 G11 chassis — relevant when the server is configured with several GPU cards for parallel inference or HPC workloads.
• 0.59 lb Cable Assembly: Light enough to route without torquing PCIe power connectors, which matters in dense rack builds where cable management affects long-term connector integrity.

Deployment Considerations:

• Verify your DL385 generation before ordering — Gen11 cable assemblies are keyed and dimensioned for that chassis specifically; a Gen10 variant looks similar but will not seat correctly or may leave GPU power rails unmated.
• Evidence for this part is limited to the distribution feed; confirm the complete GPU option kit BOM with HPE to ensure all required risers, cables, and brackets are accounted for before closing out a multi-GPU build.

Best fit: DL385 Gen11 deployments adding GPU accelerators for AI inference or HPC where the correct HPE internal power cable is the missing line item standing between a completed build and a GPU that won't initialize.
