Hp 720482-B21 800W Fs Ti Hot Plug Power Supply Kit

Our review of the Hp 720482-B21 800W FS Ti Hot Plug Power Supply Kit finds it aimed squarely at data center technicians and server maintenance pros who need a reliable, high-efficiency redundant power module. The single biggest reason to choose this unit is its combination of high efficiency and compatibility with Flex Slot HP ProLiant Gen9 servers, delivering stable 800 W output with a 96% efficiency rating and a 0.99 power factor that helps reduce waste heat and operating costs in dense rack environments.

Key Features

• 800 W capacity: Provides consistent power for demanding server configurations and supports redundant setups for minimal downtime.
• High efficiency: 96% efficiency lowers electrical losses and cuts cooling requirements in tightly packed server racks.
• Hot-plug design: The plug-in module supports hot swapping to keep servers running while replacing power components.
• Flex Slot compatibility: Built to the Flex Slot specification for straightforward installation in supported HP ProLiant DL360 and DL380 Gen9 models.
• Power factor 0.99: Near-unity power factor improves overall electrical performance and reduces reactive current draw on the supply circuit.
• Wide AC input: Accepts 200-240 V at 50-60 Hz, matching typical data center power feeds and international deployments.

Who It's For

This power supply kit is best for IT administrators running HP ProLiant DL360 Gen9 and DL380 Gen9 servers that require a hot-plug, redundant power source with high efficiency. It suits environments where uptime and energy efficiency matter, such as enterprise racks, colo facilities, and remote server closets with coordinated cooling.

It is not intended for older or non-Flex Slot server families, hobbyist desktop upgrades, or non-HP chassis that do not accept this specific plug-in module format. Buyers who need lower-wattage or non-redundant PSUs should look elsewhere.

Pros & Cons

Pros

• High 96% efficiency reduces energy waste and helps control operating costs in multi-server deployments.
• Hot-plug, redundant design enables serviceability without downtime for mission-critical systems.
• Broad compatibility with several HP ProLiant Gen9 variants simplifies stocking a single spare part for multiple models.

Cons

• Limited to HP Flex Slot Gen9 systems, so it will not fit non-compatible server chassis.
• Requires 200-240 V AC input, which may need different infrastructure in lower-voltage sites.
