World's First ATX 3.1 Platinum Flex PSU FSP650-50FUB: Pioneering Efficiency and Performance for Next-Gen IPC

FSP Power Solution GmbH introduces the World's First ATX 3.1 Platinum Flex Power Supply to the European Market.

2025-06-16

FSP sets new benchmarks with advanced industrial power supplies and proudly announces the launch of the FSP650-50FUB—the world's first Flex ATX power supply to combine ATX 3.1 compliance with 80 PLUS® Platinum certification. Developed to meet the rising demand for compact, high-efficiency power solutions in industrial computing, the FSP650-50FUB marks a significant milestone in the evolution of IPC (Industrial PC) power technology.

 

Setting a New Benchmark in Compact Power Design

 

With a standard Flex ATX form factor (150 x 81.5 x 40 mm), the FSP650-50FUB is the first globally available model to achieve both Intel's latest ATX 3.1 standard and 80 PLUS® Platinum-level efficiency. ATX 3.1 introduces advanced electrical performance and protection mechanisms for modern platforms including PCIe Gen5, while ensuring faster and more stable power delivery under dynamic loads.

The power supply supports the latest 12VHPWR and 12V-2x6 connectors, making it suitable for powering next-generation GPUs and AI accelerator cards in space-constrained industrial environments.

 

High Efficiency, Long-Term Reliability

 

The 80 PLUS® Platinum certification guarantees up to 92% conversion efficiency at typical loads (20%, 50%, 100%), significantly reducing heat generation and energy loss. This is particularly important for systems running continuously in thermally sensitive industrial settings, where efficient operation translates directly into lower energy costs and longer system lifespans

.

Additional features include:

  • Max. output power: 650W
  • Full Protection: OVP, OCP, SCP, OTP
  • MTBF > 100,000 hours at 25°C
  • High-quality Japanese industrial-grade capacitors
  • Input voltage: 90-264 Vac
  • Flexible connectors: 24-pin, 4+4 CPU, SATA, Molex, PCIe
