Supermicro SP302-1S 300 Watt Switching Power Supply

Description

The Supermicro SP302-1S (also identified as model PWS-0054) is a compact 300-watt switching power supply tailored for 1U rackmount servers and specialized workstations. Engineered by Ablecom for Supermicro, it is a staple for legacy 1U chassis where stable, continuous power delivery is required for single-processor systems.

Core Product Overview

This power supply is designed for space-constrained environments, fitting seamlessly into 1U SuperChassis models. It features active Power Factor Correction (PFC), which optimizes energy usage and ensures the unit can handle a wide range of input voltages automatically. While it is a “single” (non-redundant) module, it is built with enterprise-grade durability, boasting a mean time between failure (MTBF) of over 200,000 hours.

Compatibility

The SP302-1S is primarily validated for Supermicro’s SC813M, SC812, and SC512 chassis series. It is an ideal replacement for:

• SuperChassis Models: CSE-813M, CSE-512L-200B, and SC813 series.

• Motherboards: Supports most single-processor Intel Xeon and AMD EPYC entry-level server boards requiring a 24-pin ATX connection.
