Supermicro PWS-1K22A-1R 1200W Titanium Hot-Swap Server Power Supply

Overview:
The Supermicro PWS-1K22A-1R is a high-efficiency, hot-swappable power supply module designed for 1U rack-mount servers. It features an 80 Plus Titanium certification with up to 96% efficiency. The unit delivers 800 W at lower input voltage (100–127 VAC) and 1,200 W at higher input voltage (200–240 VAC). It includes active PFC and offers protection against over-voltage, over-current, short circuits, and overheating. Compatible with PMBus 1.2, it supports remote monitoring and redundancy control. Compact size and card-edge backplane connector ensure seamless integration into Supermicro systems, enabling hot-swap redundancy.
