PWS-601-1H Supermicro Active 600W ATX Server PSU

High-Efficiency ATX Server Power Supply for Cost-Optimized Single-PSU Deployments with the PWS-601-1H

The PWS-601-1H is a 600W ATX-form-factor server power supply engineered for 1U/2U rack systems and tower platforms that standardize on non-redundant power. By combining active PFC with 80 PLUS Gold efficiency, the PWS-601-1H supports predictable power delivery and reduced conversion loss in general-purpose compute nodes and storage servers where a single PSU is an intentional design choice.

In architectures that prioritize straightforward serviceability and consistent platform integration, the PWS-601-1H aligns with standard ATX power distribution and common server motherboard requirements. The 24-pin ATX connector and the 8-pin +12V EPS (with detachable 4-pin section) provide clean compatibility for typical CPU and board power rails, helping maintain stable operation under mixed CPU, memory, PCIe add-in, and storage I/O loads. With a 0–50°C operating range, the PWS-601-1H is suitable for controlled data center racks, edge cabinets, and lab environments where airflow design and PSU efficiency directly impact thermal headroom and component longevity.

Why Choose the PWS-601-1H?

The PWS-601-1H delivers a pragmatic density-to-performance balance for deployments that do not require PSU redundancy but still demand enterprise-grade electrical characteristics and efficiency. It is well suited for scaling out homogeneous single-PSU nodes, simplifying spares strategy, and maintaining consistent power behavior across clusters, especially in cost-optimized edge and internal infrastructure tiers.

Supermicro designs power subsystems with an emphasis on reliability, platform consistency, and operational predictability. The PWS-601-1H reflects this approach by focusing on stable power conversion, standard integration paths, and compatibility with modern server chassis expectations for ATX-based builds.

Key Applications:

• General-purpose 1U/2U compute nodes
• Single-PSU storage servers
• Edge and branch office deployments
