DEEPCOOL PN850M 850W ATX 3.1 80+ Gold Fully Modular Power Supply

The Deepcool PN850M is an 850-watt fully modular power supply built to the latest ATX 3.1 and PCIe 5.1 standards, making it a strong choice for high-performance desktop systems that demand consistent, clean power delivery. Its fully modular cable design lets you connect only the cables your build actually needs, reducing clutter inside the chassis and improving airflow across components. At the heart of the PN850M is a topology combining Active PFC, Full Bridge SRC LLC, and DC-to-DC conversion — an architecture associated with tight voltage regulation and low ripple across all output rails. The unit uses a Japanese bulk electrolytic capacitor, which is a widely recognised mark of quality in PSU construction. Hold-up time is rated at 16 ms or greater under 80% load, meaning the unit can bridge brief input interruptions without causing a system shutdown. The PN850M carries an 80 Plus Gold efficiency certification, with efficiency rated at 90% or above under typical 50% load conditions. It is also rated Gold by Cybenetics, providing an independent measure of real-world efficiency. A dedicated 12V-2x6 cable — using 16AWG copper-core wire rated for 105°C — supports up to 600W for modern discrete graphics cards, covering the power demands of current high-end GPU platforms. Cooling is handled by a 120mm fan with Fluid Dynamic Bearing (FDB), a bearing type that tends to offer quieter operation and longer service life compared to conventional sleeve bearings. Fan speed adjusts dynamically to the thermal load of the unit. The PSU also includes a comprehensive suite of protections: Over Power Protection (OPP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), Over Temperature Protection (OTP), Over Current Protection (OCP), Under Voltage Protection (UVP), Surge & Inrush Protection (SIP), and No Load Operation (NLO). The unit ships with sleeved cables as standard and is rated for operation at altitudes up to 5,000 metres above sea level. It carries a broad set of regulatory certifications including CE, FCC, CCC, cTUVus, RCM, EAC, BIS, and TUV-RH, along with compliance to WEEE, RoHS, Triman, and Proposition 65 environmental standards.
