Electricity for useful work
Reducing losses helps put more of the power entering a facility toward the computing it was built to deliver.
RETHINKING THE ENERGY BEHIND COMPUTING
Power savings.
More possibility.
A different kind of data center.
A bigger vision for the world.
The world needs more computing. Ritheum is rethinking the power behind it. Our data center technology is designed to use less electricity at the source, opening the door to less heat, less cooling and more room for what comes next.

WHO WE ARE
Rethinking data centers.
From the power up.
Ritheum Systems brings power architecture, compatible computing and building design together as one data center systems solution.
Our ambition is simple: make the computing the world depends on use less power.
- Reduce waste in power delivery.
- Integrate compatible equipment with the building around it.
- Work with developers, technology partners and operators around the world.
WHY IT MATTERS
The future needs compute.
Every watt matters.
AI, scientific discovery, business and everyday digital services all rely on data centers. Power savings can change what it takes to support them.
A lighter infrastructure burden
Less wasted power means less heat to remove, creating opportunities to reduce cooling equipment, water use and maintenance.
More possibilities for growth
More efficient systems could help expand digital capacity where power and suitable buildings are limited.
Our ambition is global.
The change starts with how we use power.
THE TECHNOLOGY
A shorter power path.
Less energy wasted.
Electricity changes form on its journey to a computer. Each conversion can lose energy as heat. Ritheum’s approach simplifies that journey.
The Coolverter brings AC-to-DC conversion and battery backup to the rack. A shared 48-volt DC supply powers compatible servers and other equipment, reducing the need for repeated conversion stages.

This describes the external power architecture. Devices still regulate voltage internally; complete-system efficiency depends on the equipment and workload.
INSIDE RITHEUM
Different at the circuit.
Different at the rack.
The Coolverter
Power Distribution Unit (PDU)
The power unit at the center of the Ritheum architecture. Its design combines conversion, six channels of 48-volt distribution and battery backup at rack level.
Bringing those functions together creates a new way to organize power delivery across compatible equipment.
Four servers. One integrated set.
Each set brings together four vertical DSi servers, two storage units and one Coolverter Power Distribution Unit. Air gaps separate the servers in the open rack.
The larger idea is a complete data center system: hardware, controls and the environment around them working toward the same power-saving goal.
THE WORK BEHIND THE VISION
Real hardware.
A growing body of evidence.
Ritheum’s technology story includes company-provided hardware designs and test results, plus a cited third-party thermal report. The next step is proving performance across complete racks and operating facilities.
135 W compared with 306 W
Company material reports these full-load readings at 55 °C for a DSi server and a reference system. Interpreting the difference requires equivalent workloads, throughput and configurations. These readings are not a facility-wide savings guarantee.
A reported 55 °C result
Company material cites TÜV Rheinland report IN25KSJW 001 for server operation at this ambient temperature. The full report and its test conditions must be reviewed before extending that result to other equipment, racks or facilities.
About these results
The power readings are company-reported. The cited thermal report must be read with its configuration and test conditions. Server results do not establish whole-rack or facility performance. Ritheum’s continued testing focuses on useful computing output, energy consumption, reliability and real operating conditions.
THE IMPORTANT SECOND BENEFIT
Power savings first.
Cooling savings follow.
When less electricity is wasted, less heat needs to be removed. That can change the role of HVAC, chillers and cooling towers in a data center.
Ritheum combines efficient power delivery with the exploration of higher-temperature operation. Together, they open the possibility of less mechanical cooling and lower demand for cooling water.
Less equipment to support
Where cooling systems can be reduced, so can the pumps, pipework and specialist maintenance that support them.
A building that breathes
The naturally aspirated concept uses engineered airflow to carry heat out of a shared server hall. The building becomes part of the thermal design.
Every data center still needs to remove heat. The achievable cooling reduction depends on climate, airflow and the limits of all installed equipment.
A NEW VISION FOR THE BUILDING
Empty space.
New possibility.
Suitable offices and warehouses could find a new purpose as data centers. Ritheum is exploring how efficient power systems and coordinated building airflow could make that transformation possible.
Office space
Warehouse space
Illustrative conversions using Ritheum-style racks. These are not completed projects or engineered layouts. Suitability depends on available power, connectivity, structure, airflow and approvals.
Existing buildings
- Assess vacant offices and warehouses.
- Check floor loading, access and ceiling clearance.
Power and connectivity
- Confirm grid capacity and fiber availability.
- Evaluate local permitting and project requirements.
Purpose-built options
- Consider new buildings where appropriate.
- Design power, equipment and airflow together.
FOLLOW THE AIR
Three levels.
One shared exhaust path.
- Ambient air enters at ground level.Side air paths supply the three levels.
- Air passes through the racks.The equipment and airflow must work as a complete system.
- Warm air rises to the roof outlet.A shared central path carries heat upward.

THE NEXT FRONTIER
AI is moving forward.
Power efficiency must too.
Ritheum is exploring how its power-saving approach can support the next generation of AI computing, across CPU-based systems and future accelerator configurations.
The research includes efficient CPU-based approaches to selected AI workloads, new hardware directions and continued development of the DSi platform.
Some data centers use CPU-only systems; AI facilities may combine CPUs and accelerators. The right architecture depends on the workload.
More capability per unit of energy
The focus is useful work: what a system can accomplish for the electricity it consumes. Future AI performance and efficiency will be established through workload-specific testing.
Power and temperature are separate questions
Future AI systems may retain a power-saving benefit without retaining the same high-temperature capability. Continued research will determine both.
AI capabilities and energy-saving goals described here are research directions, not established GPU performance results.
IN MEMORIAM
1946–2026
Arch C. Davis, P.E.
Inventor. Engineer. Founder of Davis Systems.
Ritheum’s technology began with Arch Davis’s engineering vision: a different way to power computing.
Arch developed the 48-volt server architecture at the foundation of Ritheum’s systems approach. His work brought efficient power delivery and higher-temperature computing into a shared design.
We honor the inventor behind the technology and the years of work that made this path possible.
