FSP2400-20HM — High-Reliability 2400W CRPS Redundant Power Module
A high-density Titanium PSU engineered to reduce downtime and accelerate integration.
The FSP2400-20HM is a next-generation 2400W CRPS redundant power supply designed to meet the demands of high-availability servers, networking infrastructure, and industrial automation. Built on the CRPS standard, it enables fast and predictable integration into existing chassis designs, lowering development effort and accelerating time-to-market.A key advantage of CRPS architecture is its 1+1 or N+1 redundant configuration capability. This means your system continues to operate without interruption, even if one power module fails. The remaining module(s) instantly take over the load, preventing downtime and protecting mission-critical operations.
In other words, if one module fails, the system keeps running.
Engineered for long-term stability in demanding environments, the FSP2400-20HM performs reliably from 0–55°C, supports installations up to 5,000 meters altitude, and delivers a robust 250,000-hour MTBF at 55°C and 75% load. Combined with low iTHD and comprehensive protection—OCP, OVP, OTP, short-circuit, and resettable shutdown—this power module ensures clean, stable, and continuous power delivery.
Global safety and EMC compliance reduce certification complexity, giving OEMs a cleaner path to launch. Backed by FSP's engineering support and long-term supply assurance, the FSP2400-20HM provides a durable, scalable platform that can be co-developed and custom-fit to your application needs.
The FSP2400-20HM provides stable, long-life redundant power, optimized for fast CRPS integration and demanding 24/7 workloads.
Benefit from the advantages of the FSP2400-20HM CRPS Power Supply:
- Reduced downtime through 1+1 / N+1 redundancy
- Lower operational cost thanks to Titanium efficiency
- Global certification compliance = faster time-to-market
- Fast system integration through the CRPS standard form factor

FSP2400-20HM — Maximize System Efficiency with 80+ Titanium Performance
Titanium efficiency reduces energy cost, improves thermal performance, and extends system lifetime.
The FSP2400-20HM reaches 80+ Titanium efficiency, the highest level available for AC–DC power supplies. Less power is wasted, less heat is produced, and overall system performance becomes more predictable—critical in dense server racks and networking equipment.
Key Benefits of 80+ Titanium efficiency PSU
Lower Operating Costs
Reduced power draw and cooling demand.
Higher Reliability
Lower thermal stress across the entire system.
Better Stability
More efficient conversion at high loads improves voltage regulation.
80+ Titanium efficiency of the FSP2400-20HM reduces heat, lowers operating cost, and improves PSU reliability in high-density systems.

Energy Savings Comparison: 80+ Titanium vs. 80+ Gold and Bronze
How much energy can a power supply with 80PLUS Titanium efficiency save compared to 80PLUS Gold or 80PLUS Bronze? Higher efficiency means fewer watts wasted as heat—directly reducing electricity usage, cooling demand, and total cost of ownership.
Using the FSP2400-20HM at 50% load (1500 W DC) as an example, assuming 24/7 operation (8,760 h/yr) and €0.17/kWh, the savings become clear:
