Insights
Navitas' achievement in exceeding the new 80 PLUS Ruby certification marks a significant technological leap in power supply efficiency for AI data centers. The 96.5% efficiency requirement of Ruby certification represents the most stringent standard in 14 years, and Navitas isn't just meeting it—they're exceeding it across their entire portfolio.
What makes this possible is Navitas' mastery of wide-bandgap semiconductor technologies. Their combination of GaNSafe ICs and GeneSiC Gen 3 'Fast' SiC MOSFETs enables these power supplies to achieve peak efficiencies up to
Their technological progression is equally impressive—from a 3.2kW design in 2023 that was
The proprietary IntelliWeave digital control technique demonstrates Navitas is innovating beyond just materials science into system-level optimizations. Compliance with OCP and ORv3 specifications ensures these solutions can be deployed in standardized infrastructure, removing adoption barriers for major data center operators.
The efficiency improvements Navitas has achieved address one of the most critical challenges facing AI infrastructure deployment: managing the enormous power requirements of compute-intensive workloads. While a jump from Titanium to Ruby certification might seem incremental at first glance, the real-world impact is substantial.
Consider the scale: with data centers projected to consume 1,000 TWh annually by next year, every percentage point improvement saves 10 TWh—equivalent to approximately 3.5 million tons of CO₂. A single 3.2kW Ruby-certified PSU saves 420 kWh over three years, which translates to massive operational savings when multiplied across thousands of units in hyperscale deployments.
The diversified power rating offerings (3.2kW, 4.5kW, and 8.5kW) strategically align with the industry's shift toward higher power densities required by GPU and ASIC-accelerated AI workloads. The form factor reduction—
As AI deployments continue to scale, power efficiency becomes increasingly critical from both cost and environmental perspectives. Navitas' technology allows data center operators to deploy more compute capacity within existing power and cooling infrastructure—a compelling value proposition as facilities struggle with power availability constraints and sustainability mandates. This positions Navitas strongly within the AI infrastructure supply chain as power efficiency becomes a key competitive differentiator.
AI Power Roadmap of 3.2 kW, 4.5 kW, and 8.5 kW PSUs enable new levels of energy efficiency, reduced electricity costs, and extended lifetime.
TORRANCE, Calif., March 17, 2025 (GLOBE NEWSWIRE) -- Navitas Semiconductor (Nasdaq: NVTS), the only pure-play, next-generation power semiconductor company and industry leader in gallium nitride (GaN) power ICs and silicon carbide (SiC) technology, has announced that its portfolio of 3.2kW, 4.5kW, and 8.5 kW AI data center power supply unit (PSU) designs exceed the new 80 PLUS ‘Ruby’ certification, focused on the highest level of efficiency for redundant server data center PSUs.
The 80 PLUS certification program assesses and certifies the energy efficiency of internal PSUs in computers and servers. The ‘Ruby’ certification was announced in January 2025 by 80 PLUS's administrating body, CLEAResult, following its endorsement by the Green Grid consortium.
‘Ruby’ is the most rigorous PSU efficiency standard since the ‘Titanium’ certification was released 14 years ago. In comparison, Ruby sets an additional
This new standard offers the industry a clear path to enhanced energy efficiency, helping data centers address the evolving needs of cloud storage, commercial sectors, and the increasing pressure on the grid from AI computing. For example, every Ruby-certified 3.2 kW CRPS185 PSU can save up to 420 kilowatt-hours during a 3-year lifetime. That is the equivalent of over 400 kg of CO2 emissions.
Navitas exceeds both Ruby and Titanium certifications on their portfolio of AI data center PSU reference designs, ranging from 3.2 kW to 8.5 kW, and are powered by high-power GaNSafe™ ICs and GeneSiC™ Gen 3 ‘Fast’ SiC MOSFETs.
Navitas is the established leader in AI data center solutions enabled by GaN and SiC technology. In August 2023, they introduced a high-speed, high-efficiency 3.2 kW CRPS, achieving a
“Compared with Titanium, Ruby cuts the allowable PSU losses significantly and will be critical in enabling the data center industry to reduce its carbon footprint and cut operational costs,” said Gene Sheridan, CEO and co-founder of Navitas. “With the industry set to consume 1,000 TWh annually by next year, every percentage point improvement in efficiency represents a reduction of 10 TWh, or approximately 3.5 million tons of CO2. Advances in our GaNFast and GeneSiC products enable these targets to be met and significantly exceeded.”
Navitas’ AI Power Roadmap and 80 PLUS Ruby-compliant demos can be viewed at the ‘Planet Navitas’ booth #1107 during the APEC 2025 conference, which takes place at Atlanta's Georgia World Congress Center from March 16 to 20.
