HPE J9738A 575 W Proprietary Supply

This HPE J9738A is a proprietary 575 W power supply designed for specific Hewlett Packard Enterprise hardware. It accepts 110 V AC or 220 V AC input and delivers a 54 V DC output. The unit is intended for technicians or operators maintaining compatible HPE infrastructure where this exact part number is required.

Sustained 575 W delivery at 54 V DC

The supply is rated for a continuous 575 W output at 54 V DC rather than a short-term peak. Under sustained load it maintains this voltage for the connected HPE chassis or module. Stable output depends on the host system's power management and thermal design, which regulate draw to match the unit's fixed capacity.

Proprietary form factor for HPE integration

The proprietary mechanical and electrical interface locks directly into supported HPE equipment without standard ATX connectors or mounting screws. This integration simplifies installation inside the target chassis but prevents use in generic PCs or servers. Replacement requires matching the J9738A part number exactly to ensure correct keying and power delivery.

Questions about this item

How does the J9738A handle heat and noise during continuous 575 W operation?

The unit accepts 110 V AC or 220 V AC input and delivers 54 V DC at up to 575 W; thermal and acoustic performance depends on the host chassis airflow design.

What host equipment is required for the J9738A to function?

This proprietary supply fits only HPE switch or server chassis built for the J9738A form factor; it cannot operate standalone or in standard ATX cases.

Will the J9738A work in an older HPE chassis that originally used a lower-wattage supply?

If the chassis lists J9738A as a supported part, the 575 W output at 54 V DC will power it; otherwise the proprietary connector and voltage pin-out prevent installation.
