## Long description

HP Enterprise 2900-3400W 12V 1U PLAT PSU is a high-capacity power supply unit engineered for 1U server installations and dense rack environments. It provides a variable output in the 2900–3400 watt range on a 12-volt rail and meets the efficiency and thermal profiles expected in enterprise deployments. The compact 1U form factor allows installation in space-constrained rack servers while supporting redundant power configurations typical for data center and server room infrastructures.
Advantages
This power supply delivers a high continuous wattage in a compact footprint, enabling higher server power density without increasing cabinet space. The PLAT efficiency class reduces energy loss and heat generation compared with lower-efficiency units, which helps maintain predictable thermal behavior in racks. The unit is designed for enterprise reliability with stable 12V output suitable for modern server components and redundancy schemes.
Suitable for
 1U rack servers in data centers and colo facilities
 High-density server deployments requiring redundant power
 Server rooms where compact form factor and stable high-wattage delivery are needed
Key specifications
 Output power range: 2900–3400 W
 Voltage: 12 V rail
 Form factor: 1U server power supply
 Efficiency class: Platinum (PLAT)
 Intended use: enterprise rack and data center environments
How to use
Install the PSU into a compatible 1U server chassis following the server manufacturer’s service manual. Ensure proper seating in the PSU bay and secure any latches or fasteners. Connect the appropriate power cables to the system’s power distribution or backplane as specified by the server documentation. For redundant configurations, install multiple compatible PSUs and configure redundancy modes according to the server platform’s hardware and firmware guidelines. Verify that rack power distribution units and upstream breakers support the combined load.
Usage recommendations
Operate the unit in a controlled data center environment with adequate airflow and temperature management. Use only compatible server chassis and power distribution hardware, and verify firmware and hardware compatibility before installation. When deploying multiple units for redundancy, balance load and monitor input/output parameters via available server management tools to ensure stable operation.
