## Long description

The DeepCool PN850M is an 850 W power supply unit designed for modern desktop PCs. It natively implements the Intel ATX 3.1 and PCIe 5.1 standards and delivers stable power for high-performance components via a dedicated 12V-2x6 cable and multiple EPS/PCIe ports. The unit is 80 PLUS Gold certified, uses quality internal components including a Japanese main electrolytic capacitor, and features active cooling with a 120 mm fluid-dynamic-bearing fan.
Advantages
The PN850M provides high efficiency (80 PLUS Gold) and is Cybenetics Gold rated, supports wide AC input (100–240 V), and maintains a hold-up time ≥ 16 ms at 80% load thanks to active PFC, full-bridge SRC LLC and DC-to-DC topology. Its 16 AWG copper-core 12V-2x6 cable supplies up to 600 W to modern GPUs, and the unit includes multiple protections (OPP, OVP, SCP, OTP, OCP, UVP, NLO, SIP). The high-quality components permit operation up to 5000 m altitude.
Suitable for
 Gaming PCs with high-power graphics cards
 Workstations requiring stable multi-rail power
 Systems built to ATX 3.1 / PCIe 5.1 specifications
 Upgrades from older PSUs to a Gold-efficient unit
Key specifications
 Total power: 850 W
 Efficiency: 80 PLUS Gold (≈90% typical)
 Motherboard connector: 20+4 pin ATX
 Fan diameter: 120 mm (FDB)
 AC input: 100–240 V
 GPU cable: 12V-2x6, 16 AWG copper-core (up to 600 W)
 Protections: OPP, OVP, SCP, OTP, OCP, UVP, NLO, SIP
How to use
Install the PN850M in a compatible ATX chassis and connect the 20+4 pin ATX cable to the motherboard. Use the provided EPS/PCIe connectors for CPU and GPU power according to component requirements, ensuring secure and correct seating. Connect AC power to the unit and verify BIOS/firmware settings if required for new platform features. Allow sufficient airflow around the PSU to let the 120 mm FDB fan regulate temperature automatically.
Usage recommendations
For reliable operation, ensure the PSU is installed in a case with adequate ventilation, avoid operating in extreme temperatures or dusty environments, and verify cable routing to prevent strain. When pairing with high-end GPUs, use the dedicated 12V-2x6 connector to supply up to 600 W where supported.
