PWS-563-1H Supermicro Active 600W 1U PSU

High-Density 1U Server Power Supply Module delivering efficient, protected AC-to-DC conversion with the PWS-563-1H

The PWS-563-1H is a 600W 1U server PSU module engineered for Supermicro rack platforms where power stability, thermals, and serviceability directly impact uptime. Designed as a replacement unit for Supermicro 1U systems and validated for SYS-1027R-73DAF, the PWS-563-1H supports predictable power delivery to modern CPU platforms and mixed I/O backplanes in single-node deployments.

With 80 PLUS Gold efficiency and active PFC, the PWS-563-1H reduces upstream power draw and heat generation at typical data centre loads, helping maintain chassis-level airflow budgets under active cooling. Its multi-rail DC output profile is aligned to common server board architectures, supplying high-current +12V for CPU and PCIe subsystems while maintaining regulated auxiliary rails for management and peripheral power domains. Fixed, non-modular cabling and standard server connectors streamline integration for maintenance windows, minimizing configuration variance during swap operations.

Why Choose the PWS-563-1H?

The PWS-563-1H fits organisations standardising 1U nodes where density-to-performance is limited by power and thermal constraints rather than compute. As a validated Supermicro replacement, the PWS-563-1H supports consistent fleet behaviour, predictable PSU telemetry expectations, and rapid field replacement practices that scale across racks without introducing electrical or mechanical incompatibilities.

Supermicro designs power subsystems with a focus on platform validation, long-term component availability, and data centre deployment requirements. The PSU engineering approach prioritises stable regulation, protection logic, and service-oriented integration to support enterprise maintenance processes.

Key Applications:

• 1U rack server PSU replacement and spares
• Single-node enterprise compute
• Web and application hosting infrastructure
• Virtualisation and edge consolidation
• File and directory services
