Darkflash PMT 850W 80+ Gold Power Supply Virtalähde - 850 Watt - 120 mm - ATX 3.1 - 80 Plus Kulta sertifioitu

The Darkflash PMT850A3 is an advanced 850W ATX power supply designed to power today’s most demanding PCs. It fully supports the latest ATX 3.1 and PCIe 5.1 standards, making it ideal for next-generation components like NVIDIA RTX 40 series and AMD Radeon graphics cards. With its integrated 12VHPWR connector capable of delivering 600W, the unit eliminates the need for external adapters, offering direct, efficient, and safe power delivery to GPUs.

Certified 80 Plus Gold, the PMT850A3 achieves up to 91% efficiency under typical loads at 230V. It also meets ErP Lot 3 2014 standards for low standby consumption (<0.5W) and uses a highly efficient 99% active PFC circuit to ensure consistent voltage and reduced electromagnetic interference.

Built on a powerful single +12V rail rated at 70.8A, it provides ample, stable power to GPUs and CPUs, while a DC-to-DC conversion design ensures stable +5V and +3.3V outputs. Internal components include high-grade 105°C-rated Japanese capacitors and a robust EMI filter, delivering clean, reliable performance even under stress.

Thermal performance is enhanced by a 120mm hydro-dynamic bearing fan that operates silently under low load and ramps up only when needed. Ventilation is optimized through square and hexagonal cutouts for smooth airflow and thermal dissipation.

Modular cable design with flexible flat 18AWG wiring allows users to install only the cables required, improving cable management and airflow. The unit includes compatibility for both new and legacy setups with ample connectors for CPU, GPU, and drives.

To safeguard components, the PMT850A3 integrates seven layers of protection: OVP, OPP, OCP, UVP, SCP, OTP, and NLP. It also meets 4kV surge immunity standards to shield hardware from lightning strikes and power surges.

At just 140 × 150 × 86 mm, the power supply fits snugly into most ATX cases, offering powerful, efficient, and safe operation in a space-conscious format.
