Server technology innovator Super Micro Computer Inc. has unveiled a series of Digital switching power supplies, helping its Xeon E5-based computing solutions achieve 95% efficiency.
The new PWS-1K43F-1R, PWS-1K28P-SQ, PWS-605P-1H, and PWS-341P-1H Digital switching power supplies deliver output from 340 to 1400 Watts. The new high-efficiency power supplies employ high-speed Digital power controllers with adaptive switching in place of conventional analog circuitry to generate PWM control signals.
Supermicro's digital switching power supplies also provide faster transient response to input AC line voltage fluctuations resulting in a <5% Input Current THD for an increased stability margin.
The new supplies feature:
- Platinum level (95%) efficiency.
- Remote Monitoring with PMbus 1.2.
- Node management support.
- Energy Star Server 2.0 ready features.
In analog power supplies, efficiency is optimized for a single load value based on a system's typical operation. As the load shifts away from the peak, efficiency drops. With Supermicro’s new Digital control, compensation and output parameters can be dynamically configured to match different load conditions resulting in increased efficiency across a wider range of operation.
“At Supermicro, we focus on increasing efficiency alongside performance in all areas of our product lines," says Supermicro president and CEO Charles Liang. "Our transition to Digital switching technology ahead of the industry provides our customers the highest efficiency and power factor correction gains across the widest possible load range.”
The new Digital switching power supplies are optimized for select Supermicro 1U to 4U SuperServers and are ideal for data center, cloud computing, HPC, and other resource-intensive computing applications.
