Description
DeepCool PN850D 850W 80 PLUS Gold Non-Modular ATX 3.1 PCIe 5.1 Power Supply
The DeepCool PN850D is engineered for gamers and PC builders seeking stable, efficient, and modern power delivery for gaming PCs and workstation systems. Built around the latest Intel ATX 3.1 and PCIe 5.1 standards, the PN850D is fully prepared for modern NVIDIA GeForce RTX graphics cards and next-generation desktop hardware platforms.
Delivering 850W of continuous output power, the PSU includes a dedicated native 12V-2×6 connector capable of delivering up to 600W directly to modern PCIe Gen 5 graphics cards without requiring adapters. ATX 3.1 compliance also improves transient power spike handling required by modern GPUs and CPUs.
The PN850D features a non-modular cable design with upgraded sleeved black cables for improved durability and cleaner internal aesthetics. DeepCool equips the PSU with high-grade 105°C-resistant 16AWG copper-core GPU cabling to improve long-term reliability and stable high-power GPU delivery.
Internally, the PSU utilizes Active PFC, Full Bridge SRC LLC topology, and DC-to-DC conversion architecture for improved voltage regulation, efficiency, and operational stability under demanding gaming and productivity workloads. Certified 80 PLUS Gold and Cybenetics Gold, the PN850D delivers strong power efficiency while helping reduce heat generation and power waste.
Cooling is handled by a quiet 120mm Hydro Bearing fan designed to dynamically adjust fan speeds according to PSU temperatures and load conditions for balanced cooling and reduced operating noise. The PSU is also rated to operate at altitudes up to 5000 meters due to the high-quality internal component design.
Comprehensive protection systems including OPP, OVP, SCP, OTP, OCP, UVP, SIP, and NLO help safeguard connected hardware against electrical irregularities and unexpected operating conditions. Combining modern ATX 3.1 compatibility, strong efficiency, and reliable cooling, the DeepCool PN850D is an excellent PSU choice for gaming and creator-focused desktop systems.
