Product information

Description

be quiet! POWER ZONE 2 1200 W is an ATX power supply designed for desktop PCs that require stable, high-capacity power delivery. It offers 1200 W continuous output with peak capability, 80 PLUS Platinum efficiency, active cooling via a 140 mm fan and compatibility with modern graphics cards through PCIe 5.1 / ATX 3.1 support. The unit includes a 20+4 pin motherboard connector and is finished in black with a distinctive mesh design.

Advantages

The power supply combines high efficiency (80 PLUS Platinum and Cybenetics Platinum ratings) with semi-passive zero-RPM cooling for quiet operation. An advanced LLC regulation topology and a single high-performance 12 V rail provide voltage stability under load, while the Pure Wings 3 140 mm fan and a delayed stop (2–5 minutes) reduce frequent start/stop noise. The inclusion of 90° angled 12V-2x6 connectors and PCIe 5.1/ATX 3.1 compatibility ensures support for current and upcoming graphics cards.

Suitable for

  • High-performance gaming PCs and workstations
  • Systems with multiple drives or heavy peripheral loads
  • Builds requiring PCIe 5.1 / ATX 3.1 GPU compatibility

Key specifications

  • Total continuous power: 1200 W
  • Efficiency class: 80 PLUS Platinum (approx. 92.7% typical)
  • Cooling: 140 mm fan, semi-passive zero-RPM mode
  • Fan speed range: 0–2100 RPM (active mode)
  • Input voltage and frequency: 100–240 V, 50/60 Hz
  • Motherboard connector: 20+4 pin ATX
  • Voltage regulation: LLC topology, single 12 V rail
  • Colour: Black
  • Weight: 1.88 kg

How to use

Install the PSU into a compatible ATX case following standard PC assembly procedures, connect the 20+4 pin ATX cable to the motherboard and use the provided PCIe connectors for the graphics card(s). Route SATA and peripheral cables to drives and devices as required. Ensure mains input matches 100–240 V and verify secure grounding. After powering on, the unit operates in semi-passive mode and the fan will remain off at low load until cooling is needed; during shutdown the fan may continue running for 2–5 minutes to avoid frequent restart noise.

Usage recommendations

For reliable operation, use appropriate case airflow and connect all required PCIe power connectors for modern GPUs. Allow proper ventilation around the PSU and follow the motherboard and GPU manufacturer guidelines for power delivery and connector usage.
