Keep compatible HPE ProLiant servers running with the HPE 403781-001 1000W Hot-Plug Server Power Supply. This genuine HPE spare power supply is designed for selected ProLiant G5 and related server systems and can be installed as a primary or redundant PSU in compatible configurations.
HPE spare part 403781-001 supports an AC input of 100 to 240V at 50/60Hz. Its maximum available output depends on the incoming voltage, reaching the full 1000W output on higher-voltage supplies commonly used in UK environments.
Available from Euroland IT Store in New and Refurbished condition, subject to current stock.
The HPE 403781-001 is a hot-plug AC power supply designed for selected HPE ProLiant servers. It provides up to 1000W of output and can be used as the primary PSU or as part of a redundant power configuration where supported by the server.
This is an older-generation HPE server component, so the exact part number is particularly important when sourcing a replacement.
If you are replacing a failed PSU and the existing unit carries spare number 403781-001, matching that number gives you a much stronger basis for selecting the correct replacement than choosing a PSU based on wattage alone.
One detail worth understanding about the 403781-001 is that the available output varies according to the incoming AC voltage.
HPE’s technical information specifies the following maximum rated output:
| Nominal Input Voltage | Maximum Rated Output |
|---|---|
| 100V | 800W |
| 120V | 950W |
| 208V | 1000W |
| 220V | 1000W |
| 230V | 1000W |
| 240V | 1000W |
This means the PSU reaches its full 1000W rated output at 208V to 240V input.
For UK buyers using a normal 230V AC supply, this is particularly relevant because the unit is capable of its full 1000W rated output at that nominal input voltage.
The HPE 403781-001 is a hot-plug power supply. In compatible HPE ProLiant configurations, it can be installed as either the primary power supply or as part of a redundant power setup.
Redundant power can be valuable in business and server environments because a compatible system equipped and configured with multiple power supplies can provide protection against the failure of a single PSU.
The server itself must support the required redundant configuration. Do not assume that adding a second PSU automatically provides redundancy without checking the configuration of your particular ProLiant server.
A New HPE 403781-001 is suitable for buyers who specifically require an unused replacement unit for an existing compatible HPE ProLiant server.
New old-stock server parts can become harder to source as hardware generations age, so availability may vary.
Check the product condition shown when ordering to confirm whether the unit you are purchasing is New.
A Refurbished HPE 403781-001 can be a practical choice when maintaining an older HPE ProLiant server.
Refurbished units have been previously used and prepared for resale. They may show minor cosmetic signs of previous installation, but this does not necessarily affect their intended operation.
For organisations maintaining legacy server hardware, a refurbished matching spare can offer a practical alternative to replacing an otherwise serviceable server.
Check the condition and warranty information shown for the selected product before purchasing.

Part number 403781-001 is associated with selected HPE ProLiant servers, including models within the following families:
Compatibility can vary by server configuration and revision. Always compare the spare number on your existing PSU and check your server’s hardware specification before ordering.
If your existing power supply is labelled 403781-001, this is the most useful reference when looking for the correct replacement.
You may see 403781-001 listed alongside other numbers when searching for this power supply.
Commonly associated numbers include:
These numbers can refer to option, assembly or related identifiers associated with the power supply.
Do not rely on a related number alone when purchasing. Compare your existing PSU label and server model with the product details, or ask us to confirm compatibility.
Before ordering, check the label on the power supply currently installed in your server.
Look for the HPE spare part number 403781-001.
You should also check:
Do not purchase a server PSU based only on the fact that it is rated at 1000W. Physical fit, electrical design and server compatibility are also important.
If you are uncertain, send Euroland IT Store the server model and the numbers printed on your existing power supply before ordering.
Older HPE ProLiant systems are still used by many businesses for specific workloads, backup systems, test environments and legacy applications.
A failed power supply does not necessarily mean the entire server needs replacing.
Where the rest of the hardware continues to meet your requirements, installing the correct replacement PSU can be a straightforward way to extend the useful working life of the server.
This can be particularly useful when replacing the server would also involve application migration, operating system changes or other infrastructure work.
Euroland IT Store supplies server parts and IT hardware to businesses, IT professionals, repair companies and other customers across the UK.
When ordering HPE 403781-001, check the condition shown on the product page to see whether the available unit is New or Refurbished. You should also review the current warranty, stock and delivery information before completing your purchase.

HPE 403781-001 is a 1000W AC hot-plug server power supply designed for compatible HPE ProLiant servers. HPE identifies it as a spare power supply that can be installed as a primary or redundant unit in compatible systems.
Yes, but maximum output depends on the AC input voltage. HPE specifies 800W at 100V, 950W at 120V and the full 1000W output at 208V, 220V, 230V and 240V nominal input.
Yes. HPE’s published power specifications show a maximum rated output of 1000W at a nominal 230V input.
Yes. HPE describes 403781-001 as a hot-plug power supply.
Yes, in a compatible server and configuration. HPE states that the PSU can be installed as a primary or redundant supply. The server must support the appropriate redundant power configuration.
The part is associated with selected HPE ProLiant systems including the DL380 G5, DL385 G2/G5, ML350 G5 and ML370 G5 families. Compatibility should still be checked against the exact server configuration and existing PSU part number before purchase.
The numbers are associated with the same power supply family, but they represent different types of HPE identifiers. 399771-B21 is commonly identified as the option number, while 403781-001 is the HPE spare part number. When replacing an existing PSU, use the numbers on your original unit to confirm compatibility.
Choose New if you specifically require an unused unit and stock is available. A Refurbished unit can be a practical replacement for an older compatible ProLiant server. Check the condition and warranty listed for the particular unit before ordering.
Warranty terms can depend on whether the product is sold as New or Refurbished. Check the warranty information shown on the product page for the condition you are purchasing.
Check the spare number printed on your existing power supply and your exact HPE ProLiant server model. If the existing PSU shows 403781-001, you have a strong part-number match. If the numbers differ, confirm compatibility before ordering.
Yes. Please send us your HPE ProLiant server model, the server’s serial number, and the HPE spare or assembly number printed on the label of your existing PSU. Our team can then help you check the product details and confirm compatibility before you make your purchase.
