Reliable Power Delivery with Fujitsu PSUs

Fujitsu power supply units (PSUs) are engineered to deliver stable, efficient energy to critical IT systems. These components are vital to maintaining operational continuity, ensuring your servers receive clean, consistent power even under fluctuating loads. At Direct Hardware Supply, we provide a wide selection of refurbished Fujitsu PSUs – ideal for replacing failed units or supporting infrastructure upgrades with dependable, enterprise-grade power solutions.

Engineered for Enterprise Stability

Fujitsu PSUs are designed for mission-critical server environments, featuring high efficiency ratings and built-in protections against voltage irregularities, surges, and short circuits. Many models include hot-swappable functionality, allowing technicians to replace a PSU without shutting down the server. Redundant power configurations – commonly used in Fujitsu Rack Servers – help safeguard uptime by providing automatic failover in the event of component failure.

Optimized for Energy Efficiency

Modern Fujitsu PSUs are built to maximize energy performance while minimizing waste. Units often meet 80 PLUS certification standards (Silver, Gold, or Platinum), indicating high conversion efficiency across a range of power loads. This reduces both electricity usage and heat output, easing the burden on cooling systems and helping organizations reduce long-term operating costs. Pairing an efficient PSU with thermal management components like Fujitsu Heat Sinks creates a balanced, efficient system architecture.

Supporting a Range of Configurations

From entry-level tower servers to high-density rackmount deployments, Fujitsu offers power supply units in various wattages and form factors. Whether you're supporting older PRIMERGY models or high-performance systems requiring over 1000W of clean power, there is a PSU built to meet your technical requirements. These units are also designed with cable and airflow management in mind, maintaining easy integration within complex data center environments.

Refurbished Power Supplies That Perform

All refurbished Fujitsu PSUs available from Direct Hardware Supply are tested for electrical stability, connector integrity, and sustained output under load. These units offer the same level of performance and reliability as new hardware, making them a cost-effective choice for IT teams focused on maximizing system uptime without exceeding budget constraints.

Selecting the Right PSU for Your Infrastructure

When choosing a power supply, be sure to match the wattage, connector type, and mounting compatibility with your server model. Redundant configurations and hot-swap features may also influence your selection. Our team is available to help identify the right PSU for your application.
