Linklieo has expanded its 80 PLUS Ruby certified data center power supply portfolio, with models spanning 1600 W to 5500 W. The range targets server platforms that need higher-efficiency AC-DC conversion at rising rack power levels, including GPU server deployments.
The Ruby series is offered in five power tiers: 1600 W, 2000 W, 3200 W, 4500 W, and 5500 W. Across the lineup, Linklieo is using the CRPS form factor (Common Redundant Power Supply), a standardized, hot-swappable architecture intended to simplify maintenance and support redundant power supply configurations in critical systems.
Linklieo also points to the “compact 73.5 mm CRPS” standard promoted by OCP, positioning the mechanical standardization as a way to keep power modules interoperable across server platforms while maintaining hot-swap serviceability.
For electrical performance, Linklieo lists three efficiency- and grid-facing metrics across its CRPS power supplies: no-load power from 3.05 W to 8.81 W, 5% load efficiency from 92.12% to 92.79%, and power factor above 0.99 at 20% load, approaching 0.999 at full load. For operators, the low-load numbers are the ones to scrutinize, because many fleets spend meaningful time at light utilization where conversion losses can quietly add up across thousands of nodes.
Linklieo’s broader server PSU portfolio spans 550 W to 5500 W, and the company is positioning the Ruby lineup for enterprise servers, cloud infrastructure, storage systems, and AI-driven computing. More details on the Ruby lineup are available at linklieo.com.
