Know before you buy
The 80 PLUS Titanium rating is the highest efficiency certification available, meaning this unit converts up to 95.6% of power from your wall into usable energy for your PC. This results in less wasted energy as heat and lower power consumption compared to lower-rated power supplies.
Yes, it is designed specifically for near-silent operation. It uses a patented frameless Silent Wings fan with a fluid dynamic bearing, which remains virtually inaudible even under heavy system loads.
Absolutely. Because every cable is detachable, you only need to plug in the specific cables your components require. This significantly reduces cable clutter, improves internal airflow, and makes the installation process much cleaner.
Yes, the Dark Power 12 850W is ATX 3.0 and PCIe 5.0 ready, ensuring it is compatible with the power delivery requirements of modern, high-performance GPUs.
The unit features an overclocking key that allows you to switch between multi-rail and single-rail operation. Multi-rail mode provides extra stability for sensitive components, while single-rail mode is often preferred for high-draw overclocking scenarios.
The unit is built with premium Japanese 105°C capacitors, which are industry-standard for high-end power supplies due to their longevity and heat resistance. This reliability is further backed by a comprehensive ten-year manufacturer's warranty.
