An Immersion Cooling PSU is a specialized power supply designed to be completely submerged in dielectric coolants for data center or High-Performance Computing (HPC) applications. Unlike traditional air or liquid-cooled PSUs, it operates reliably in liquid environments and features anti-corrosion properties and resistance to dielectric fluid degradation.

Immersion PSUs utilize specialized components and a fanless design, allowing them to operate continuously within dielectric coolants. Compared to standard PSUs, they offer significantly enhanced stability and an extended lifespan.

No, not all coolants are suitable. Please provide us with the specifications of your dielectric fluid so we can accurately evaluate compatibility.

Currently, the entire FSP CRPS series can be customized to support immersion cooling applications based on specific client requirements.

The key is eliminating high-consumption cooling fans and maximizing conversion efficiency. FSP's immersion cooling PSUs feature a fanless design, directly removing fan power consumption and vibration. Paired with 80 PLUS® Titanium efficiency, FSP significantly reduces heat waste, helping data centers drive their PUE (Power Usage Effectiveness) close to 1.0, making it the premier choice for green data centers.

Material compatibility is the core of reliable liquid cooling systems. FSP invests heavily in R&D to rigorously screen and test electronic components for chemical compatibility with various dielectric fluids. FSP products utilize specialized conformal coating and sealing processes to ensure that power supplies submerged long-term will not suffer from chemical reactions or corrosion, guaranteeing absolute server reliability.

AI and HPC computing generate extreme heat that traditional air cooling struggles to handle. FSP’s immersion PSUs, designed specifically for high-density computing, deliver extreme power density (e.g., 2000W+) within a standard CRPS form factor. Leveraging the superior thermal conductivity of fluids, FSP power supplies provide stable, high-wattage output in a smaller footprint, perfectly supporting the immense computing demands of high-end GPU servers.

Stable temperatures and isolation from environmental factors are key. FSP's immersion PSUs use fluid to maintain heat-generating components at a lower, stable temperature range, avoiding the hot spots common in air-cooled systems. Additionally, the immersion environment isolates equipment from moisture, dust, and sulfur. FSP's design further eliminates fan vibration risks, drastically increasing the MTBF (Mean Time Between Failures) and overall lifespan of your hardware.

Standardization is critical to lowering the barrier to entry. FSP provides immersion power products that comply with industry standards such as M-CRPS or CRPS. This means System Integrators (SI) and data centers can utilize FSP's liquid cooling PSUs for seamless upgrades without needing to heavily modify existing chassis designs, perfectly balancing innovative technology with legacy architecture compatibility.

Absolute silence is a major highlight of immersion technology. FSP's immersion cooling PSUs completely remove mechanical fans, achieving true 0dB operational noise. This design is highly ideal for Edge Computing nodes, office environments, or highly vibration-sensitive laboratories, decisively solving the high-frequency noise and vibration interference challenges of traditional servers.

Mechanical design must account for fluid resistance and ergonomics. For the unique environment of an immersion tank, FSP optimized the handle design and mechanical strength of our PSUs to facilitate easy vertical insertion and extraction for maintenance personnel. Concurrently, FSP products support hot-swappable functionality, ensuring that power modules can be replaced safely and swiftly without powering down the system.
