PN850M at a Glance
Introduction
The DeepCool Gamer Storm PN850M 850W 80 PLUS Gold Fully Modular Power Supply (R-PN850M-FC0B-JGIN) is designed for modern gaming desktops, performance PCs and compatible workstation builds that need dependable power delivery and support for current graphics-card connections.
Built to the Intel ATX 3.1 standard and compatible with PCIe 5.1 power requirements, the PN850M includes a dedicated 12V-2x6 cable rated for up to 600W. It is designed to handle specified short-duration power excursions while providing power for compatible current and next-generation components.
The fully modular design lets builders connect only the cables required by their configuration. Factory-sleeved cables provide a cleaner appearance, while the 140mm-long chassis fits many standard ATX-compatible cases.
An 80 PLUS Gold rating, dynamic 120mm fluid dynamic bearing fan and an internal design combining active PFC, full-bridge SRC LLC and DC-to-DC conversion round out this power supply.
Key Features
850W Continuous Power
Provides 850W of rated power for compatible gaming and productivity systems, with the capacity to support demanding CPU and GPU combinations within the unit's limits.
80 PLUS Gold Efficiency
Gold certification indicates efficient power conversion under defined test conditions. DeepCool also lists Cybenetics Gold certification for the PN850M series.
Native 12V-2x6 GPU Cable
Includes a dedicated 16-pin 12V-2x6 cable rated for up to 600W, using 16AWG copper conductors and insulation rated for 105°C, for compatible graphics cards.
ATX 3.1 and PCIe 5.1
Designed around modern power-supply requirements, including support for specified transient power excursions and the newer 16-pin GPU power connection.
Dynamic 120mm FDB Fan
The fluid dynamic bearing fan adjusts its speed according to the PSU's cooling requirements to balance airflow and noise.
Comprehensive Protection
Includes over-power, over-voltage, short-circuit, over-temperature, over-current, under-voltage, surge/inrush and no-load operation protections.
Power Delivery and Cooling Technology
The PN850M combines active power factor correction with full-bridge SRC LLC topology and DC-to-DC conversion. DeepCool specifies a power-good signal of 100–150ms and a hold-up time of at least 16ms at 80% load.
Its ATX 3.1 design is intended to accommodate specified short-duration power excursions. The dedicated 12V-2x6 cable supports up to 600W for compatible GPUs, but the card's own power requirements and the complete system configuration must still be checked.
A dynamic 120mm FDB fan adjusts to the cooling needs of the power supply. The unit is specified for operation in ambient temperatures from 0°C to 40°C and altitudes up to 5,000 metres above sea level.
DeepCool lists a Japanese bulk electrolytic capacitor, a minimum 16ms hold-up time at 80% load and an MTBF of 100,000 hours. MTBF is a reliability statistic, not a guaranteed service life.
Technical Specifications
Specifications are based on DeepCool's official PN850M documentation. The listed connector quantities describe the supplied cable set; confirm the exact regional package and compatibility before purchase.
Ideal Use Cases
Modern Gaming PCs
A suitable option for compatible gaming systems that need 850W of continuous power and a native 16-pin GPU connection.
Content Creation
Supports compatible desktops for video editing, rendering, development and other demanding creative workloads.
Clean Custom Builds
Fully modular, sleeved cables let builders connect only the leads they need and improve the appearance of cable routing.
Long-Term PC Builds
The ATX 3.1 design, native 12V-2x6 cable and 10-year limited warranty make it a consideration for compatible builds intended for long-term use.
Before You Build
- Check the recommended PSU wattage for your exact processor and graphics card, including transient power requirements.
- The native 12V-2x6 cable is rated for up to 600W. Follow the graphics-card manufacturer's instructions and ensure the connector is fully seated.
- Use only the modular cables supplied with this PSU or replacements explicitly confirmed as compatible with the exact model. Modular PSU cables are not universally interchangeable.
- The chassis measures 150 × 140 × 86mm. Confirm case clearance and allow sufficient room for the GPU power cable's recommended bend radius.
- DeepCool's warranty documentation excludes certain abnormal uses, including mining-related use under its stated terms. Review the applicable regional warranty conditions before purchase.
