FSP has launched the updated Hydro M PRO ATX3.1 Series, available in 700W and 800W variants. This new line brings the trusted Hydro M PRO platform into compliance with the latest ATX 3.1 and PCIe 5.1 standards, ensuring full compatibility with modern hardware and next-generation GPUs.
The new Hydro M PRO ATX3.1 maintains FSP’s hallmark semi-modular design and reliability while integrating several key improvements to efficiency, stability, and cooling. With up to 88% efficiency, active PFC ≥0.9, and 450V, 105°C capacitors, it offers consistent power delivery under demanding conditions. A 120mm hydraulic bearing fan ensures silent, long-lasting operation.
Features
• Complies with ATX12V V3.1 & EPS12V V2.92 standards
• Efficiency greater than or equal to 88% at typical load (80 PLUS Bronze certified)
• Semi-modular ribbon cables for cleaner builds
• 450V, 105°C heavy-duty capacitors for long lifespan
• 120mm hydraulic bearing fan for low noise and better cooling
• +5V & +3.3V DC-to-DC module design for improved stability
• +12V single-rail design supports power-hungry GPUs
• Comprehensive protection: OCP, OVP, OPP, SCP
The updated design also highlights a stronger focus on cable management and energy efficiency. With DC-to-DC conversion and ErP 2013 compliance, the new FSP Hydro M PRO consumes less power in standby mode while reducing ripple noise and extending component longevity.
Compared to the previous Hydro M PRO series, the ATX 3.1 revision introduces a 12V-2x6 connector for next-gen GPUs, improved internal circuitry, and quieter operation—all while maintaining the same durable, semi-modular design and Bronze-rated performance.
Pricing and availability for the FSP Hydro M PRO ATX3.1 series have yet to be announced. Learn more about the FSP Hydro M PRO ATX3.1 power supply units at the FSP website.
