Product information

Description

The FSP FlexGURU PRO 500W is a 500 W power supply unit designed for NAS and storage servers. It features a 24-pin ATX connector, non-modular all-black round cables and an active cooling system with a 40 mm internal fan. The unit is 80 PLUS Gold certified and supports AC input from 100–240 V at 50–60 Hz, providing stable power delivery for compact server and IPC environments.

Advantages

The FlexGURU PRO series combines a 40 mm fan for reduced noise and effective thermal performance with an efficiency of around 90% for lower energy loss. All-black round cables provide a tidy, professional appearance inside chassis, while Japanese electrolytic capacitors help maintain stable outputs and long-term reliability. The product also includes an optional 1U bracket for use as a 1U IPC power supply and meets IEC 62368 safety standards.

Suitable for

  • NAS and storage servers
  • Compact IPC and 1U systems (with included bracket)
  • Home or small office server builds requiring efficient, reliable PSU

Key specifications

  • Total power: 500 W
  • Efficiency: 90% (typical), 80 PLUS Gold certified
  • Motherboard connector: 24-pin ATX
  • Fan diameter: 40 mm (internal)
  • Input voltage/frequency: 100–240 V, 50–60 Hz
  • Product colour: Black

How to use

Install the FlexGURU PRO 500W into your server or IPC chassis following the chassis manufacturer’s installation guidelines. Connect the 24-pin ATX connector to the motherboard and attach the remaining non-modular cables to drives and peripherals as required. If converting to a 1U configuration, install the supplied 1U bracket before securing the PSU. Ensure the AC input rating matches your mains supply before powering on.

Usage recommendations

Place the PSU in a location with adequate ventilation, keep dust away from the 40 mm fan, and avoid operating at ambient temperatures beyond the manufacturer’s specified range. Regularly check cable connections and use within the rated 500 W load to ensure optimal performance and reliability.
