Product information

Description

The Chieftec MRT-5320G 320W power supply unit is designed for continuous server operation and provides stable, efficient power delivery. It supports an AC input range of 100–240V at 47–63Hz and includes a 24-pin ATX motherboard connector. With 80 PLUS Gold certification and an efficiency around 90%, this compact silver PSU measures 150 mm (W) x 185 mm (D) x 87 mm (H) and is fitted with two 40 mm fans for cooling.

Advantages

The MRT-5320G offers high energy efficiency thanks to its 80 PLUS Gold certification, delivering up to approximately 90% efficiency under typical loads. Its wide AC input voltage range makes it suitable for varied power environments, while dual 40 mm fans provide active cooling for steady 24/7 operation. The standard 24-pin ATX connector ensures compatibility with common server motherboards in a compact silver housing.

Suitable for

  • Small servers and network appliances
  • Continuous 24/7 operation environments
  • Systems requiring a compact, efficient PSU

Key specifications

  • Total power: 320 W
  • Efficiency: 90%
  • 80 PLUS certification: 80 PLUS Gold
  • Motherboard power connector: 24-pin ATX
  • Fan diameter: 40 mm (two fans)
  • Input voltage / frequency: 100–240 V, 47–63 Hz
  • Colour: Silver
  • Dimensions: 150 mm (W) x 185 mm (D) x 87 mm (H)

How to use

Install the Chieftec MRT-5320G into the server or chassis according to the manufacturer’s installation guidelines. Connect the 24-pin ATX connector to the motherboard and attach any required peripheral connectors as needed. Ensure the AC input matches the local mains voltage (100–240 V) and secure proper airflow around the unit so the dual 40 mm fans can maintain cooling during continuous operation.
