## Summary description

The Darkflash PMT850A3 is an 850W power supply with 80 Plus Gold certification, ensuring high efficiency and reliability. It features a fully modular design for easy cable management, silent operation with a 120mm fan, and multiple protection mechanisms including over-voltage and short-circuit protection. Ideal for high-performance gaming rigs and workstations, it delivers stable power for demanding components.

## Long description

Darkflash PMT850A3 is an 850W ATX power supply designed for modern high-performance systems. It supports ATX 3.1 and PCIe 5.1 standards, includes a built-in 12VHPWR (12+4 pin) cable for up to 600W to power current-generation GPUs, and holds an 80 Plus Gold efficiency certification. The unit is fully modular, fits standard ATX cases (140 × 150 × 86 mm), and incorporates Japanese capacitors and an active PFC topology to provide stable voltages under dynamic loads.
Advantages
The power supply provides up to 91% efficiency at typical load (80 Plus Gold), low standby consumption (\<0.5W ErP Lot3), and a single powerful +12V rail rated for 70.8A. It includes extensive protections (OVP, OCP, OPP, UVP, SCP, OTP, NLP) and 4kV surge immunity. A 120 mm hydro-bearing fan delivers quiet, long-life cooling with a semi-passive profile that starts at 30% load. Modular flat 18AWG cables simplify cable routing and improve airflow.
Suitable for
High-end gaming PCs with NVIDIA RTX 40 or AMD Radeon GPUs
Workstations and developer rigs with dynamic CPU/GPU loads
System builds requiring a compact ATX 850W PSU with modular cabling

How to use
Install the Darkflash PMT850A3 into a standard ATX case using the supplied mounting screws. Connect the 20+4 pin ATX and 4+4 CPU cables to the motherboard, attach PCIe 6+2 or the 12VHPWR 12+4 cable to the GPU as required, and route only the modular cables you need to optimize airflow. Observe the manufacturer’s guidance for mounting the 12VHPWR cable: keep the connector at least 35 mm from the side panel and avoid sharp bends. Connect the power cord to mains and power on the system; the unit supports dynamic loads and will regulate voltages automatically.
Usage recommendations
To ensure long-term reliability, use the built-in 12VHPWR cable without adapters when possible, maintain good case airflow, and verify that system peak power demands remain within the 850W rating. Follow cable routing guidance for the 12VHPWR connector to prevent mechanical stress and ensure stable power delivery.
