New Taipei City, March 4th, 2026 – Compuware Technology Inc. (Compuware), a leading pioneer in high-efficiency power solutions, is proud to announce that its power supply (CPR-5521-2M1) has officially achieved the 80 PLUS® Ruby certification. This milestone achievement places Compuware among an exclusive group of global manufacturers capable of meeting the industry’s most stringent efficiency standards. By integrating this Ruby-certified PSU as the core of its advanced Power Shelf Series, Compuware is providing data centers with a premier sustainable solution for transitioning to the massive power demands of modern AI computing.

Efficiency At The Highest Level
The 80 PLUS Ruby certification, introduced by CLEAResult in 2025, targets high-power redundant PSUs in servers and data centers. This standard imposes far more stringent requirements, achieving efficiencies that surpass the Titanium tier.

The CPR-5521-2M1 PSU with 80 PLUS Ruby certification serves as the power core of Compuware’s 19-inch, ORv3-compliant 33kW Power Shelf. Its superior efficiency contributes to stronger power delivery, improved thermal performance, and enhanced energy savings—all essential for the long-term, stable operation of AI computing workloads. This reflects Compuware’s commitment to environmental sustainability. The 33kW Power Shelf is available on the market and has received substantial orders and positive customer feedback.

Engineered for Reliability and Scalability
Compuware’s Power Shelf (CPR-3331 Series) features a 19” form factor and is fully compatible with the ORv3 standard, offering a modular and scalable power solution for the most demanding AI and HPC environments. Key features include:

• High Density: 1U height supporting up to six 5.5kW hot-swappable Ruby-certified rectifiers.
• Extreme Peak Power: Features EDPP (Electrical Design Peak Power) support of 180% (500μs) to handle the intense, dynamic power spikes of advanced AI processors.
• Advanced Monitoring: Equipped with a Power Management Controller (PMC) and ASPEED 2620 BMC for real-time telemetry and predictive maintenance.
• Multi-Shelf Parallelism: Supports shelf-to-shelf communication for up to 8 power shelves and BBU shelves, allowing for massive power distribution and backup in consolidated clusters.

"Securing the 80 PLUS® Ruby certification is a testament to our engineering team's ability to solve the most difficult power challenges," said Bill Liang, President at Compuware. "As data centers require more energy, high efficiency is no longer optional—it is a global necessity. Compuware is focused on delivering that power with the highest possible efficiency. We believe solving the power issue is not only critical for the AI industry, but for our Earth as well. This translates directly into lower utility costs and higher profitability for our customers. We are not just meeting the requirements of today; we are committing to the environment for the next generation tomorrow."

Availability and Future Roadmap
In addition to the 33kW CPR-3331 Series Power Shelf and the 80 PLUS® Ruby-certified CPR-5521-2M1 PSU, Compuware Technology is collaborating with multiple major partners to develop next-generation power solutions, including 72kW and 110kW Power Shelves.
