PWS-203-1H Supermicro Active 200W 1U Server PSU

High-Efficiency 1U Internal Power Supply Module for Compact Server Chassis with the PWS-203-1H

The PWS-203-1H is a 200W 1U internal PSU module designed for compact Supermicro server and workstation chassis where a fixed, non-redundant power architecture is acceptable. It targets low-power single-CPU platforms, edge appliances, and lab systems that require predictable power delivery without the complexity of hot-swap redundancy.

With 80 PLUS Gold efficiency and Active PFC, the PWS-203-1H supports energy-aware rack deployments by reducing conversion losses and improving input power quality under variable load. Integration is straightforward through standard power cabling, including a 20-pin ATX connector for the mainboard, an 8-pin EPS12V feed for CPU power domains, plus dedicated SATA and 4-pin Molex outputs for storage and auxiliary devices. This connector mix aligns well with common 1U motherboard layouts, PCIe add-in cards powered via the board, and compact storage backplanes where controlled airflow and stable rails are critical.

Why Choose the PWS-203-1H?

The PWS-203-1H provides a pragmatic density-to-performance fit for 1U systems that prioritize simplicity, predictable thermals, and serviceable replacement over redundant PSU topologies. For IT teams standardizing spares across appliance fleets, the PWS-203-1H enables consistent power characteristics and straightforward maintenance windows while supporting enterprise protection requirements.

Supermicro designs power subsystems to align with data centre operational expectations, focusing on electrical stability, efficient conversion, and component-level safeguards. The PWS-203-1H incorporates protection features such as OVP, OCP, and SCP to help maintain platform integrity during fault conditions and transient events.

Key Applications:

• 1U entry server PSU replacement
• Edge appliances and security gateways
• Lab and test bench systems
• Low-power single-socket platforms
