## Long description

Power Supply XPG COREREACTOR II 850W is a fully modular ATX power supply designed for desktop systems that require stable, high-efficiency power delivery. The unit complies with Intel ATX 3.0 and ATX 3.1 specifications, includes a 12VHPWR-ready design and an 80 PLUS Gold certification, and is available in a white finish. With a total power of 850 W, universal AC input (100–240 V, 47–63 Hz) and a 120 mm active cooling fan, this PSU is suitable for mid-to-high level CPUs and GPUs in gaming, workstation, and content-creation builds.
Advantages
The XPG COREREACTOR II 850W provides high energy efficiency thanks to its 80 PLUS Gold certification, reaching up to approximately 91.40% efficiency at typical loads. Its fully modular cabling reduces case clutter and simplifies installation. The intelligent fan curve keeps noise low while maintaining thermal control, and premium 105°C Japanese capacitors improve long-term stability and reliability. The unit supports ATX 3.0 & ATX 3.1 features including 12VHPWR compatibility and is engineered to tolerate large power excursions for stable performance under sudden load spikes.
Suitable for
Gaming PCs with mid-to-high range GPUs
Workstations used for video editing and 3D rendering
Creator rigs and AI development systems requiring ATX 3.0/3.1 compatibility
System builds that benefit from fully modular cabling and quiet cooling

How to use
Install the XPG COREREACTOR II 850W into a compatible ATX chassis, secure the PSU with the mounting screws, and connect the modular cables to the motherboard (20+4 pin), CPU, GPU and peripherals as required. Ensure the AC mains input matches the device rating (100–240 V) and use the included power cable and connectors. Route modular cables to optimize airflow, and verify that the 12VHPWR connector is used only with compatible graphics cards that require it. After connections are secured, power on the system and monitor voltages and fan operation during the first boot.
Usage recommendations
For reliable operation, use the COREREACTOR II 850W within its specified input range and avoid continuous operation near maximum wattage for extended periods. Allow proper case ventilation to assist the intelligent fan curve, and choose compatible 12VHPWR adapters/cables provided by the GPU or manufacturer to ensure safe high-power connections. Regularly check system grounding and connectors during maintenance.
