865412 – HPE 800W Flex Slot Platinum Hot-Plug Low Halogen Power Supply Kit 94% Efficiency 80 Plus Platinum Certified for ProLiant Gen10 Servers

Overview on HPE Smart Storage Hybrid Capacitor

The HPE 800W Flex Slot Platinum Hot-Plug Low Halogen Power Supply Kit (P38995-B21) is a high-efficiency power solution designed specifically for modern enterprise servers. This kit features the unique HPE Flexible Slot form factor, which is 25% smaller than previous generation power supplies. This compact design provides additional internal space within the server chassis for extra options, such as storage or networking, while improving overall airflow and performance.

Because it is 80 PLUS Platinum certified, this power supply ensures up to 94% energy efficiency. Consequently, it significantly reduces power waste and overall operational costs in high-density data centers.

High-Efficiency Power Management

This power supply is engineered to minimize energy loss without impacting server performance. Specifically, it includes the following:

• 80 PLUS Platinum Certification: Guarantees a minimum of 94% efficiency at 50% load.

• Low Halogen Design: Complies with environmental safety standards to reduce ecological impact.

• Right-Sizing Strategy: The Flex Slot architecture allows users to select the exact power output needed, avoiding “trapped” power capacity.

• High-Line and Low-Line Support: Operates seamlessly across input ranges from 100V to 240V AC.

Serviceability and Redundancy

HPE has prioritized uptime and ease of maintenance with this model:

• Tool-less Hot-Plug Access: Allows for rapid installation or replacement without powering down the server.

• Redundant Operation: When paired with a second identical PSU, it supports N+1 power resiliency.

• Load-Balanced Mode: Distributes the electrical load across both units for consistent wear and optimal efficiency.

• Integrated Health Monitoring: Fully compatible with HPE iLO for real-time power reporting and hardware status alerts.

Broad Server Compatibility

The P38995-B21 is a critical part for several generations of HPE hardware. It is specifically required or compatible with:
