Flex Slot Platinum Hot Plug Low Halogen Power Supply Kit P38995-B21 HPE 800W

The P38995-B21 is an enterprise-grade 800W hot-plug power supply kit designed by Hewlett Packard Enterprise for use in ProLiant Gen10, Gen10 Plus, and Gen11 server platforms. Built around HPE's Flex Slot form factor, this power module delivers optimized power delivery, industry-leading energy efficiency, and robust reliability for mission-critical data center environments.

With 80 Plus Platinum certification, it achieves up to 94% conversion efficiency, significantly reducing power consumption, heat generation, and long-term operational costs. Featuring hot-plug capability, the unit supports non-disruptive replacement without shutting down the host server, ensuring continuous availability for 24/7 business operations.

The low-halogen design complies with global environmental and safety standards, making it suitable for modern data centers with strict regulatory requirements. Its compact Flex Slot footprint saves internal chassis space while maintaining full compatibility with a wide range of HPE rack and tower servers.

At the core of the P38995-B21 is a highly efficient 800W power delivery system certified 80 Plus Platinum, which maximizes energy usage across varying load conditions. This high efficiency reduces overall power waste and lowers cooling demands within server enclosures, supporting more sustainable and cost-effective data center operations.

The wide input voltage range of 100-240V AC enables seamless deployment in global regions without manual adjustment, ensuring consistent performance across different grid infrastructures. Designed for durability, the power supply includes integrated overvoltage, overcurrent, and short-circuit protection mechanisms to safeguard server components and connected hardware.

Low halogen materials enhance fire safety and reduce environmental impact, aligning with modern green IT initiatives. Combined with intelligent thermal management, the unit maintains quiet and stable operation even under extended high loads, extending service life and minimizing the risk of unexpected downtime.

The P38995-B21 uses HPE's Flex Slot design, offering versatile compatibility across a wide portfolio of HPE servers. It is fully supported on ProLiant DL360, DL380, DL385, ML110, ML350, and other Gen10/Gen11 rack and tower systems. This cross-platform support simplifies inventory management, standardizes spare parts, and lowers total cost of ownership for IT teams managing mixed server environments.

Hot-plug functionality allows administrators to replace or add power supplies during operation, supporting redundant power configurations that improve system fault tolerance. The kit includes the power supply unit and necessary mounting components for tool-free installation. Its compact construction maximizes interior space for additional storage drives, expansion cards, and cooling solutions, supporting higher system density in modern data centers.
