Power supply unit Supermicro PWS-1K68A-1R 800 W 1U, 80 PLUS Titanium, silver

The Supermicro PWS-1K68A-1R is a compact 1U server power supply unit that delivers a continuous 800 W output and supports peak output up to 1600 W for short-duration demands. Designed for rack-mounted systems and mission-critical environments, this silver PSU measures 76 × 336 × 40 mm and accepts AC input from 100–240 V. The unit implements active PFC and meets 80 PLUS Titanium efficiency standards with an efficiency around 91%, offering consistent power delivery in a high-density 1U form factor.

Advantages

This Supermicro power supply combines high efficiency with a small footprint suitable for 1U servers. The 80 PLUS Titanium certification and active PFC reduce wasted energy and thermal load. PMBus 1.2 support enables remote monitoring and management of voltage, current and power parameters, and the design supports flexible redundancy control for fault-tolerant installations. The silver-metal housing provides robust mechanical protection and fits standard server trays and chassis.

Suitable for

• Rack-mounted 1U servers in data centers
• High-density compute nodes where space and efficiency are critical
• Redundant power configurations and hot-swap server bays
• Mission-critical systems requiring remote power monitoring and control

How to use

Install the PWS-1K68A-1R into a compatible 1U server chassis or tray following the server manufacturer's installation procedure. Connect the AC input to a properly rated mains source within the 100–240 V range and secure any locking mechanisms or retention screws. Configure PMBus monitoring through the system management controller or compatible monitoring software to view voltage, current and power metrics and to set redundancy behavior where supported. Perform a controlled power-up and verify that the supply operates within expected temperature and voltage tolerances.

Usage recommendations

Use this unit in environments with adequate airflow and within the server chassis manufacturer’s specified ambient temperature ranges to maintain efficiency and longevity. For redundant configurations, pair identical or compatible Supermicro PSUs and configure the redundancy policy through PMBus or the server management interface. Ensure regular firmware and monitoring software updates for accurate PMBus reporting and remote management.
