DARKFLASH PMT 850W 80 Plus Gold Power Supply

Darkflash PMT 80 Plus Gold 850W Computer Power Supply (Black)

The Darkflash PMT850A3 is an ATX power supply designed for modern PCs for gamers, creators, and professionals. It offers full support for the ATX 3.1 and PCIe 5.1 standards, providing stable power for the latest graphics cards, including the NVIDIA RTX 4000 and AMD Radeon. An integrated 12V HPWR (600W) connector, 80 Plus Gold-certified high efficiency, and advanced security features make it a solid foundation for high-performance configurations.

PCIe 5.1 and 12VHPWR Support

The built-in 12VHPWR cable (12+4 pin, 650 mm) provides up to 600W of power for modern PCIe 5.1-compliant graphics cards, eliminating the need for adapters. The connector design has been optimized for safety – it is recommended to install the cable 35 mm away from the side panel and avoid excessive bending to prevent mechanical damage and power transfer issues.

ATX 3.1 compliant stability

The ATX 3.1 standard allows for peak power consumption of up to 200% of rated power. The power supply complies with Intel's Power Supply Design Guide (PSDG), ensuring it can handle the dynamic loads of modern GPUs and CPUs. You can count on the reliability and stability of the entire system, even under extreme operating conditions.

High efficiency and savings

The 80 Plus Gold certification confirms that the Darkflash PMT850A3 achieves up to 91% efficiency (for a typical load at 230V). This means less energy wasted as heat and lower electricity bills. Additionally, the power supply meets the ErP Lot3 2014 standard, resulting in power consumption of less than 0.5W in standby mode. The 99% efficiency of the active PFC system translates into better use of grid power, reduced losses, and reduced electromagnetic interference. This system ensures stable supply voltage under varying load conditions.

One strong +12V line

The power supply utilizes a single +12V rail design with a maximum current of 70.8A, allowing full utilization of the power to power the most important components: the GPU and CPU. Combined with the DC-to-DC circuit, +5V and +3.3V voltages are generated from the main +12V rail, providing greater stability and reduced energy loss. This solution simplifies load management and reduces the risk of overloading individual rails.

Advanced Cooling

The power supply utilizes a 120mm fan with a hydrodynamic bearing, which is characterized by quiet operation and long life. The fan only activates after reaching 30% load, and its speed increases proportionally to cooling demand. The casing is designed with perforations in a square (top) and hexagonal (rear) arrangement, ensuring efficient airflow. This solution helps maintain low noise levels during office work and ensures effective cooling under heavy loads.

Modular design and wiring

The Darkflash PMT850A3 features a modular cable system, allowing you to connect only the cables you need. Flat, flexible 18AWG cables are included to simplify case interior organization and improve airflow. It's designed for compatibility with both the latest motherboards and legacy configurations with multiple drives and expansion cards.

Premium Security

The power supply is equipped with a complete set of 7 protections – overvoltage (OVP), overload (OPP), overcurrent (OCP), undervoltage (UVP), short circuit (SCP), overheating (OTP), and no-load (NLP). Additionally, it meets 4kV surge resistance standards (Surge 4K), effectively protecting computer components from lightning strikes and network interference. These protections operate in real time and automatically respond to any voltage irregularities or overloads, increasing the security of the entire platform.

Component Reliability

High-quality Japanese capacitors with a resistance of up to 105°C ensure voltage stability even under sustained load. An efficient switching transformer guarantees adequate power without overheating, and an EMI filter eliminates interference from the power grid. Heatsinks in the power supply efficiently dissipate heat, keeping internal components cool.

Compact ATX form factor

Despite its high power, the power supply fits into a standard ATX case measuring 140 x 150 x 86 mm. This makes it a perfect fit for most modern cases and allows for better use of internal space.
