Product information

Description

The DeepCool PF400 400W power supply unit provides stable and efficient power delivery for desktop PCs and small servers. Certified to the 80 PLUS 230V EU Standard, it reaches around 85% efficiency at typical 50% load and includes a 120 mm hydraulic-bearing fan, flat black fixed cables and comprehensive protection features. The unit supports an AC input of 220–240 V at 50 Hz and offers a 20+4 pin ATX motherboard connector along with multiple SATA power leads.

Advantages

The PSU's 80 PLUS 230V EU certification reduces energy waste and operating temperatures, improving overall efficiency. A 120 mm silent hydraulic bearing fan decreases noise while extending component lifespan. Flat black fixed cables simplify cable management and save internal space. Built-in protections guard against overpower, over-voltage and short-circuit conditions.

Suitable for

  • Home and office desktop PCs requiring up to 400 W
  • Small form-factor systems with limited internal space
  • Budget builds where stable, certified efficiency is needed

Key specifications

  • Total power: 400 W
  • Efficiency: 80 PLUS (approx. 85% at 50% load)
  • Input: 220–240 V AC, 50 Hz
  • Motherboard connector: 20+4 pin ATX (cable length 55 cm)
  • Fan: 120 mm hydraulic/fluid bearing
  • Product colour: Black
  • Form factor: ATX

How to use

Install the DeepCool PF400 in a compatible ATX case aligned with the PSU mounting holes and secure it with screws. Connect the 20+4 pin ATX connector to the motherboard and attach the SATA power cables to drives as required (cable lengths vary). Ensure AC mains voltage matches the unit's 220–240 V requirement before connecting the included AC power cord. Maintain unobstructed airflow around the 120 mm fan and route cables to avoid contact with moving parts.

Usage recommendations

For reliable operation, operate the PSU within its rated 400 W output and avoid prolonged operation near maximum load. Keep the interior of the PC clean and ensure adequate case ventilation to maintain low operating temperatures and fan life.
