Why Choose This Product?

• 1400W power capacity - Gives supported HPE servers considerably more PSU capacity than 800W Flex Slot alternatives, making it appropriate for higher-demand configurations.
• Platinum Plus positioning - Provides a documented efficiency-focused HPE power option for organizations evaluating server power consumption and data-center operating costs.
• Hot-plug serviceability - Helps maintenance teams replace a compatible PSU without treating the operation as a complete server replacement, particularly when redundant power is configured.
• Flex Slot standardization - Uses HPE's established Flex Slot PSU architecture, simplifying replacement planning for compatible infrastructure.
• High-line AC compatibility - Supports 200–240VAC input, matching common enterprise data-center electrical designs. 
• OEM procurement confidence - The exact 720620-B21 option number plus generic and spare references reduces ambiguity when sourcing replacement hardware.
• Platform-specific validation - HPE explicitly lists the PSU for platforms such as the ProLiant DL380 Gen9 and SimpliVity 380 Gen9, providing a stronger compatibility reference than generic third-party PSU listings. 
• Lifecycle and TCO value - Replacing a failed PSU can restore a supported server without replacing the complete chassis, helping preserve existing infrastructure investment when the rest of the system remains serviceable.
