DEEPCOOL Gamer Storm PN850M 850W 80 Plus Gold Fully Modular ATX 3.1 Power Supply

The DeepCool Gamer Storm PN850M is an 850-watt fully modular power supply built to the ATX12V V3.1 and PCIe 5.1 standards, making it a forward-compatible choice for high-performance desktop builds. Dual-certified for efficiency — carrying both the 80 Plus Gold and Cybenetics Gold ratings — the PN850M delivers 90% or greater efficiency under typical 50% loads, helping reduce wasted heat and energy draw during everyday use. At the heart of the PN850M's electrical design is an Active PFC + Full-Bridge SRC LLC + DC-to-DC topology. This combination contributes to stable, clean power delivery across all rails. The unit maintains a hold-up time of 16 ms or greater at 80% load, and the Power Good Signal is rated between 100 and 150 ms, both of which contribute to reliable system stability during transient events. The power supply ships with a dedicated 12V-2×6 cable rated for up to 600W, built with a high-grade 16AWG copper-core design and rated to 105°C — well suited to current-generation discrete graphics cards that demand sustained high-wattage delivery. Five EPS/PCIe ports are available alongside the 12V-2×6 connector, providing flexibility for a wide range of component configurations. Cooling is handled by a 120mm fan using a Hydro Dynamic Bearing (HYB), which adjusts speed dynamically in response to the unit's thermal needs. This fan profile helps keep noise levels low during lighter workloads while scaling up when the system demands more cooling. The PN850M is rated for operation from 0°C to 40°C and has been tested for use at altitudes up to 5,000 metres above sea level. The fully modular cable design allows users to connect only the cables their system requires, reducing clutter and improving airflow inside the chassis. Included cables arrive pre-sleeved, adding a cleaner aesthetic without requiring aftermarket modifications. Protection circuitry covers over-power (OPP), over-voltage (OVP), short-circuit (SCP), over-temperature (OTP), over-current (OCP), under-voltage (UVP), no-load operation (NLO), and surge/inrush protection (SIP). The unit carries regulatory certifications including CE, FCC, CCC, cTUVus, RCM, EAC, BIS, and TUV-RH, as well as ErP 2014, WEEE, RoHS, Triman, and P65 compliance.
