darkFlash PMT850 850W fully modular power supply

Built for modern GPU power

The darkFlash PMT850 is an 850 W fully modular ATX power supply certified to 80 PLUS Gold and Cybenetics Platinum. It ships with a native 12V-2x6 cable that complies with ATX 3.1 and PCIe 5.1 specifications. All capacitors are Japanese units rated for 105 °C, and a 135 mm FDB fan handles cooling in a 150 mm deep chassis.

Suits single high-end graphics builds

This unit targets builders installing one RTX 30, 40 or 50 series card that draws up to 600 W through the 12V-2x6 connector. The fully modular cable set keeps unused leads out of the case, aiding airflow in compact ATX enclosures. Systems planning multi-GPU configurations via SLI or CrossFire should look elsewhere because the PMT850 does not support those technologies.

850 W ceiling with 600 W GPU headroom

The +12 V rail can deliver the full 850 W rating, leaving ample margin for CPU, storage and peripherals after a 600 W graphics card. Efficiency stays above 90 % at typical loads, reducing waste heat. Protection circuits include over-voltage safeguards and a power-good signal. Continuous operation is rated beyond 100 000 hours MTBF.
