Three barriers between AI and reliable power

Generative AI and HPC workloads are creating unprecedented demand for power infrastructure. Rack densities are growing 10× in five years. Hyperscale operators demand Titanium-class efficiency. AI factories tolerate zero downtime. Three barriers define the engineering problem — and all three must be solved simultaneously.

Efficiency: >97%

Titanium-class efficiency at every conversion stage. Every percentage point saved at 1 MW means 10 kW less heat — and a real capex reduction in cooling infrastructure.

Power density: >1 kW/L

Rack density is growing from 10–15 kW/rack to 200+ kW/rack by 2028. WBG semiconductors (SiC, GaN) and planar magnetics are the only viable path to meet these targets.

Reliability: >10⁶ h MTBF

AI factories run 24/7 with zero tolerance for downtime. Physics-of-Failure design, RAMS analysis and thermal budget management are non-negotiable engineering requirements.

Mission-critical power engineering, now for AI infrastructure

Premium PSU is not entering the data centre market from zero. We are transferring over 40 years of engineering experience from railway traction (EN 50155, EN 61373), defence and grid infrastructure — sectors where failure is simply not an option — into a market that now demands exactly those same standards.

CPD-Ready 125V DC Kit — from pilot to hyperscale

Turn-key power infrastructure for AI compute, designed for native OCP Open Rack v3 (ORv3) architecture and full DCIM integration. Available in four power configurations — 20, 40, 60 and 72 kW — to match rack density targets from edge to AI factory scale.

• N+1 redundancy: hot-swap modules with seamless failover — zero downtime during maintenance windows.
• OCP ORv3 compliant: native support for the Open Compute Project Open Rack v3 architecture.
• Unified telemetry: SNMP / Modbus / REST — full integration with DCIM platforms.
• Pre-validated EMC: CE, IEC 62368-1, UL ready — integrated EMC-checked BOM.
• WBG switching stages: SiC-based conversion for >95% efficiency at full load.
• Co-development ready: custom configurations of voltage, form factor, firmware and interface.

Standard catalogue models for data centre architecture

Over 40 years engineering power where failure is not an option

Our engineering credentials come from the most demanding industrial applications. Every methodology we apply in AI data centre projects — Physics-of-Failure, RAMS, thermal budget analysis — has been validated under real-world mission-critical conditions:

• Railway traction and high-speed rail: converters and inverters qualified to EN 50155, EN 61373 and EN 45545-2, including cold-start designs for −40 °C arctic operation and cross-border certification management. The same thermal and reliability design methodology applies to AI rack power.
• Urban rail systems: full RAMS analysis and EN 61373 vibration qualification, with rapid prototyping cycles.
• Grid infrastructure: modular inverter deployments across distribution networks. Grid-grade reliability and modular architecture are directly applicable to DC microgrid and AI campus designs.

Power electronics for AI data centres — technical Q&A

What power electronics does Premium PSU offer for AI data centres?

Premium PSU offers custom power electronics for AI data centres, including the CPD-Ready 125V DC Kit (20/40/60/72 kW, OCP ORv3 compliant), modular 48V rectifiers (CKR-3600), DC-DC converters (CRS-2000/3000), AC/DC isolated front-ends (ODS-1500/3000) and DC UPS systems (EPS-200/2000). All products feature SiC/GaN WBG switching for >97% efficiency, PMBus/SNMP/REST telemetry and N+1 redundancy design.

Is Premium PSU OCP ORv3 compliant?

Yes. The CPD-Ready 125V DC Kit is designed for native OCP Open Rack v3 (ORv3) architecture, supporting hot-swap modules, N+1 redundancy and full DCIM integration via PMBus, SNMP and REST interfaces. Premium PSU actively monitors OCP specifications and roadmaps to maintain alignment.

What is the MTBF of Premium PSU power supplies for data centres?

Premium PSU standard platforms achieve MTBF >10⁶ hours, validated through Physics-of-Failure (PoF) design methodology and RAMS (Reliability, Availability, Maintainability and Safety) analysis applied from day one of each project. Thermal budget allocation, Coffin-Manson fatigue modelling and elimination of electrolytic capacitors in critical paths are standard practice.

Can Premium PSU co-develop custom power solutions for AI infrastructure?

Co-development is at the core of how Premium PSU works. We assign dedicated engineers, run co-simulations, and optimise thermal and electrical budgets together with the customer. An NDA is signed on day one. Prototype delivery in under 14 weeks is our demonstrated standard. Custom configurations include voltage levels, form factors, firmware, communication interfaces and mechanical integration.

What efficiency class do Premium PSU AI data centre products achieve?

Premium PSU products target ≥97% efficiency at rated load, meeting Titanium-class requirements (80 PLUS Titanium, ≥96% at 50% load, ≥94% at 20% load). WBG SiC-based switching stages and planar magnetics are the primary enablers. Efficiency is guaranteed across the full operating temperature range for data centre environments.

What certifications do Premium PSU AI data centre products carry?

Products are certified or in certification for IEC 62368-1, CE (EU), UL (North America) and Energy Star. The CPD-Ready 125V DC Kit also targets 80 PLUS Titanium qualification. EMC compliance (CISPR 32, IEC 61000) is validated in-house at Premium PSU’s EMC laboratory in Barcelona.
