## Long description

be quiet! Dark Power 13 Power Supply Unit 850 W is a high-efficiency ATX power supply designed for high-end PCs. It delivers 850 W of continuous power with up to 95.4% efficiency (80 PLUS Titanium) and supports modern graphics cards through native 12VHPWR and multiple PCIe 6+2-pin connectors. The unit combines advanced topology, Japanese 105°C capacitors and an optimized cooling concept to provide stable, long-lasting performance with very low standby power.
Advantages
The Dark Power 13 850W offers industry-leading efficiency certified by 80 PLUS Titanium, reducing power consumption and heat output. Its ATX 3.0 compliance with a native 12VHPWR connector and additional PCIe 6+2-pin cables ensures compatibility with current and next-generation GPUs. The PSU features a frameless Silent Wings 135 mm fan and a split fan inlet that improve airflow while minimizing noise. High-quality Japanese 105°C capacitors and advanced full-bridge LLC with active rectifier topology deliver stable voltage regulation, low ripple and reliable operation under heavy transient loads.
Suitable for
High-end gaming PCs with modern GPUs, including PCIe 5.0/12VHPWR cards
Workstations and content-creation systems that demand stable power delivery
Systems with overclocked CPUs or GPUs requiring strong transient response
Builders who prefer modular sleeved cables for cleaner cable management
When it may not be suitable
This 850 W PSU is oversized for basic office or light-home systems where power demands are low; such systems may not benefit from the unit’s high efficiency or advanced features. It may also be more capacity and cost than needed for small-form-factor builds with limited space, as the unit is designed for mid-tower and larger cases.

How to use
Install the Dark Power 13 850W into an ATX-compatible case and secure it to the PSU mounting area. Connect the 20+4 pin motherboard cable and required CPU and PCIe power cables to your components; use the native 12VHPWR connector for compatible next-generation GPUs or the 6+2-pin PCIe cables for current cards. Use the modular cable system to attach only the cables you need, routing them to improve airflow. If overclocking, use the included overclocking key to switch between the default four 12V-rail mode and the single-rail mode as required by your configuration. Ensure proper case ventilation and verify all connections before powering on.
What to consider before purchase
System power draw: confirm 850 W suits your CPU, GPU and peripherals
Case compatibility: check physical dimensions and ventilation for a full-size ATX PSU
GPU connector requirements: verify whether your GPU needs a native 12VHPWR or 6+2-pin connectors
Cable routing needs: assess whether modular, 120 cm cables meet your layout
Noise expectations: the unit is optimized for very low noise but still requires case airflow
Usage recommendations
For best results, pair the Dark Power 13 850W with a well-ventilated mid-tower or larger case, use the modular cables to minimize clutter, and select the appropriate power-rail mode when overclocking to ensure stable operation under heavy, transient loads.
