HPE - 30-49448-01 - DEC/AlphaServer ES40/45 720W PSU

The HPE 30-49448-01 is a 720W power supply unit (PSU) designed as a replacement power module for DEC/AlphaServer ES40 and ES45 systems. It is intended for enterprise environments where stable power delivery and predictable serviceability are critical for legacy AlphaServer infrastructure.

When maintaining mixed estates, this PSU is often sourced alongside platform spares such as SYSTEM BOARD components, and can be part of a broader HPE spare strategy. For teams standardising on HPE refurbished inventory, you can also align procurement across HPE product lines to simplify lifecycle support and sparing.

Key Features

Key technical characteristics of this PSU for AlphaServer maintenance and repair:

• 720W power output rating to support stable power delivery in DEC/AlphaServer ES40/ES45 configurations.
• Compatibility with DEC/AlphaServer ES40 to restore correct power capacity and electrical fit for that chassis generation.
• Compatibility with DEC/AlphaServer ES45 to keep supported power redundancy and serviceability aligned with the platform design.
• PSU module form factor intended for server power bays to enable straightforward replacement during maintenance windows.
• Enterprise PSU design characteristics to help maintain continuous operation in 24/7 data center and lab environments.
• Suitable as a like-for-like spare part to reduce risk when replacing a failed unit in existing AlphaServer power configurations.
• Designed for integration with the server’s internal power distribution to support stable operation of CPU, memory, and I/O subsystems.
• Appropriate for maintenance providers and system integrators supporting legacy AlphaServer fleets to keep critical workloads online longer.

Refurbished Quality and Warranty

This is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished spares are a practical way to extend the lifecycle of existing AlphaServer environments, control budget compared to buying new, and reduce electronic waste.

All products from Direct Hardware Supply include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. If you are also maintaining broader HPE infrastructure, we can help source related platforms such as RACK SERVER and BLADE SERVER systems for consistent sparing and fleet support.
