ASUS ROG-THOR-850P2-GAMING 850 W power supply

850 W ATX power supply for high-end builds

This 850 W ATX unit targets enthusiasts who need clean, stable power for demanding graphics cards and multi-core processors. The fully modular design means only the cables you actually use stay inside the case, simplifying routing and improving airflow. Lambda A++ certification confirms very low acoustic output even under load. An integrated OLED panel shows real-time power draw without extra software.

Premium build with quiet cooling and flexible cables

ROG heatsinks cover critical components to keep temperatures down and reduce fan speed requirements. The 135 mm wing-blade fan uses PWM control and a 0 dB mode that stops the blades completely at low loads. All cables are individually sleeved and supplied with combs for the 24-pin, 8-pin and 6-pin connectors, giving a tidy, professional finish. Aura Sync compatibility allows the addressable RGB lighting to be synchronised with other compatible hardware.

Check case depth and GPU power needs before ordering

The unit is 160 mm deep, so verify that your chassis allows at least that much clear length from the mounting face. Your graphics card must be compatible with either the single 16-pin PCIe connector or the three 6+2-pin PCIe connectors provided. The motherboard requires both a 24-pin and two 4+4-pin CPU power headers. Ten SATA and six peripheral connectors are available for drives and accessories.
