HPE P03178-B21 Power Supply Unit 1000 W

The HPE P03178-B21 Power Supply Unit 1000 W delivers reliable 1000 W output with an AC input range of 100–240 V and high efficiency rated at 96% (80 PLUS Titanium). Its compact flexible-slot form factor is 25% smaller than the previous generation, freeing internal space for additional server options and helping reduce overall data center power consumption while maintaining IT performance. The silver PSU is compatible with HPE ProLiant Gen10, HPE ProLiant DL300 Gen9, HPE Apollo 2000 and HPE Apollo 4000 series servers.

Advantages

This HPE flexible slot power supply provides up to 96% efficiency and 80 PLUS Titanium certification to reduce power waste and lower server power requirements. The 25% smaller form factor increases internal rack space for expansions. Tool-less hot-plug access enables faster serviceability, and broad compatibility across HPE ProLiant Gen10, DL300 Gen9 and Apollo 2000/4000 lines simplifies spare parts management and can reduce data center operational costs.

Suitable for (tasks / use cases)

• Enterprise rack servers requiring 1000 W redundant or primary power
• Data center environments focused on energy efficiency and reduced power waste
• Service environments needing tool-less, hot-plug PSU replacement for fast maintenance
• Standardizing spare inventory across HPE ProLiant Gen10, DL300 Gen9 and Apollo 2000/4000 series

How to use

Install the HPE P03178-B21 into a compatible HPE server power bay following the server manufacturer’s service manual. The flexible-slot design supports tool-less, hot-plug insertion and removal: ensure the server is configured for hot-swap operation or follow proper shutdown procedures if hot-swap is not available. Verify AC input voltage is within 100–240 V and confirm redundant configurations through server management interfaces after installation.

Recommendations

Use this PSU in supported HPE ProLiant Gen10, HPE ProLiant DL300 Gen9, HPE Apollo 2000 and Apollo 4000 systems; maintain at least one redundant supply where recommended to avoid downtime, and follow HPE guidelines for grounding and cooling to preserve efficiency and service life.
