Product information

Description

The Silverstone GM400 1U power supply unit provides a continuous 800 W output in a compact 1U server form factor. Built for rack and small‑form server applications, it accepts an AC input voltage range of 90–264 V at 47–63 Hz and delivers power through a 20+4 pin ATX motherboard connector. The PSU carries an 80 PLUS Silver efficiency rating and uses an active cooling system with a 40 mm fan. Its metal chassis in silver finish measures 123 mm (W) x 270 mm (D) x 41.5 mm (H) and weighs 2.15 kg.

Advantages

The Silverstone GM400 combines high output with a slim 1U profile, enabling deployment in space‑constrained server racks and compact chassis. The 80 PLUS Silver certification indicates reduced energy losses compared with standard units, while the active fan cooling maintains thermal stability during continuous operation. The 20+4 pin ATX connector ensures compatibility with a wide range of motherboards, and the robust metal housing provides mechanical reliability for server environments.

Suitable for

  • 1U rack servers and compact server chassis
  • Network appliances and storage systems requiring continuous 24/7 power
  • Workstations or small servers where space and efficient cooling are critical

How to use

Install the Silverstone GM400 into a compatible 1U bay or compact chassis following your chassis manufacturer’s instructions. Connect the AC input to a properly rated mains outlet or power distribution unit, then attach the 20+4 pin ATX connector to the motherboard power socket. Ensure adequate airflow around the PSU intake and exhaust to allow the 40 mm fan to maintain cooling. Verify voltage range and grounding before powering on.

Usage recommendations

For reliable operation, use the PSU in environments within the specified AC range and ambient temperatures appropriate for server equipment. Maintain clear airflow paths and dust‑free intake areas; schedule periodic visual inspections of the fan and connectors. When deploying in racks, use compatible mounting hardware and follow cooling and power distribution best practices.
