Product information

Description

The be quiet! BN338 1000 W power supply unit is an 80 PLUS Platinum certified ATX PSU designed for high-efficiency operation in desktop systems. Delivering 1000 W continuous power with a peak capability up to 1070 W, this PSU features a 20+4 pin ATX motherboard connector, a 135 mm Silent Wings-style fan for quiet active cooling, and fully modular sleeved cables up to 100 cm to simplify installation and cable management.

Advantages

With 80 PLUS Platinum certification and an efficiency of around 91.8%, the BN338 reduces power consumption and heat output compared with lower-efficiency models. The large 135 mm fan provides effective cooling while keeping noise low, and the use of high-quality components contributes to stable voltage regulation and long-term reliability. Modular, sleeved cables help maintain clean builds and improve airflow inside the case.

Suitable for

  • High-performance gaming PCs and workstations requiring up to 1000 W continuous power
  • Systems using modern GPUs and CPUs that benefit from stable 12V delivery
  • Enthusiast builds where quiet operation and neat cable management are priorities

Key specifications

  • Total power: 1000 W (peak 1070 W)
  • Efficiency: up to 91.8% (80 PLUS Platinum)
  • Motherboard connector: 20+4 pin ATX
  • Fan diameter: 135 mm
  • Modular sleeved cable lengths: up to 100 cm (SATA cable options: 550, 700, 850, 1000 mm)
  • Input voltage: 100–240 V
  • Color: Black
  • Weight: 1.85 kg

How to use

Mount the PSU in your PC case following the case manufacturer’s instructions, connect the 20+4 pin ATX connector to the motherboard and attach the required modular power cables to GPUs, drives and other components. Ensure the input voltage selector (if present) matches your mains supply and secure all connections before powering the system. Allow for adequate ventilation around the PSU fan intake to maintain low operating temperatures.

Usage recommendations

For stable long-term operation, pair the BN338 1000 W with components whose combined continuous power draw stays below the PSU’s 1000 W rating; reserve the peak capability for short transient loads. Keep the PSU and surrounding area free of dust and ensure good case airflow to maintain efficiency and reduce noise.
