PWS-504P-1R Supermicro 500W 1U Server PSU

High-Efficiency 1U Redundant Server Power Module for resilient rack operation with the PWS-504P-1R

The PWS-504P-1R is a 1U hot-swap AC power supply module engineered for Supermicro rack platforms that require redundant power delivery and continuous operation. In compute and virtualisation nodes, stable power is a foundational dependency for CPU and memory integrity; the PWS-504P-1R supports these platforms with 80 PLUS Titanium efficiency to reduce thermal load, improve rack-level power budgeting, and sustain predictable performance under sustained utilisation.

Designed for modern data centres and edge racks, the PWS-504P-1R integrates PMBus 1.2 telemetry and power management to support monitoring workflows, capacity planning, and proactive maintenance. Redundant-capable architecture enables N+1 style deployment in 1U systems, while integrated protections including OCP, OVP, and SCP help isolate electrical faults before they impact mainboard power domains, PCIe expansion stability, or storage backplanes in mixed I/O configurations.

Why Choose the PWS-504P-1R?

The PWS-504P-1R provides a high-density, power-efficient redundancy element for 1U Supermicro servers where uptime and operational control are non-negotiable. By combining Titanium-class efficiency with PMBus visibility, it supports tighter power envelopes, lower cooling demand, and consistent fleet behaviour across scale-out deployments, from compact edge clusters to larger virtualisation racks.

Supermicro power engineering focuses on platform-validated interoperability, serviceable hot-swap design, and long-life operation aligned with data centre standards for availability, monitoring, and controlled maintenance windows.

Key Applications:

• 1U redundant rack server power refresh
• Virtualisation and private cloud nodes
• General-purpose compute clusters
• Edge racks with constrained power and cooling
• PMBus-monitored data centre power operations
