Product information

Description

The FSP FlexGURU 300W is a compact Power Supply Unit designed for small servers and compact PC systems requiring up to 300 W of total power. It features a fully modular cabling system that lets users attach only the cables they need, improving airflow and simplifying cable management. The unit accepts an AC input of 100–240 V at 50–60 Hz and includes a standard 20+4 pin ATX motherboard connector. A 40 mm fan with ball bearing technology provides active cooling while maintaining low noise levels.

Advantages

Fully modular connectors allow quick disassembly and replacement of cables, making installation and troubleshooting faster. The wide AC input range supports use in different regions without additional adapters. Its compact form factor and black finish suit small server enclosures and compact chassis, while 90% efficiency reduces energy loss and heat generation.

Suitable for

  • Small servers and micro-ATX / Flex-ATX systems
  • Compact or space-constrained PC builds
  • Systems where modular cabling and improved airflow are priorities

How to use

Install the PSU into a compatible Flex-ATX or small-form-factor chassis following the chassis manufacturer’s instructions. Connect the 20+4 pin ATX connector to the motherboard and attach only the required modular cables to peripherals and drives. Ensure the AC mains cable matches local requirements and connect the PSU to a grounded outlet. Maintain unobstructed airflow around the 40 mm fan and verify secure cable routing to avoid contact with moving parts.

Usage recommendations

For reliable operation, use the FSP FlexGURU 300W in systems whose total component power draw does not exceed 300 W, allow clearance for ventilation, and periodically check cable connections. When troubleshooting, the modular design enables fast cable isolation and replacement.
