Features

  • Dark Power 14 1200W is certified with 80 PLUS Titanium and Cybenetics Titanium for a stunning energy efficiency rating of up to 95.42%. This provides lots of benefits for a high-end system, including less power consumption and an overall cooler and quieter operation.
  • Dark Power 14 1200W is an ATX 3.1 PSU and comes with both native integration of the two 12V-2x6 connectors for next-generation PCIe 5.1 graphics cards and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and perfect for current and future high-end systems.
  • A button on the rear of the power supply allows switching between a balanced active cooling mode, where the Silent Wings fan spins all the time, or a semi-passive mode, where the fan does not spin under low load and only starts when additional cooling is required for more demanding operations. A post-ventilation setting keeps the fan spinning after cooling down for a short period of 25 minutes to prevent frequent and noisy starts and stops.
  • A large heat sink connects to the parts of the power supply that need the most cooling and dissipates a large portion of the heat. Even though a Titanium efficiency power supply does not generate as much heat, active cooling is required to prevent overheating issues under high load. Nothing less than the very best fan of be quiet! cools Dark Power 14 1200W. Being integrated directly into the heat sink, this high-end fan is immune to vibrations and sits unshakably. A 6-pole fan motor and fluid-dynamic bearing ultimately make for exceptionally long lifetime and minimal power consumption.
  • Dark Power 14 1200W is particularly suitable for overclocking. With the simple push of a button, you can manually switch between multi-rail and single-rail mode. This gives you full overclocking control between the default four 12V-rail mode and the alternative massive single-rail operation.
  • Dark Power 14 1200W is state-of-the-art technology. With an Active Rectifier and full bridge LLC technology it offers some of the most advanced technologies available, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation.
  • Each component in Dark Power 14 1200W is carefully selected. That is why we have exclusively used high-quality Japanese capacitors for this PSU. They are rated to 105C, ensure stability, reliability, and a long operating life.
  • Modular, sleeved cables measuring up to 120cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling in even the largest PC cases.

  • If versatility and stability are what ur looking for, this is it.
Size: 1200W Style: Dark Power 14
This was one of the best Purchases I've made for my PC build! Absolutely quiet and stable. Loaded with options for conntections. Im running a high end build with a RTX 5080, AMD 9850 X3D, a 4tb NVME M.2, and several power hungry accessories. This PSU absolutely ended my GPU power faults!

  • Great PSU
Size: 1200W Style: Dark Power 14
Bought this power supply from another retailer. Works great, very quiet, and gives you the option of single or multi rail and fan on/off. Likely the best psu on the market. Only thing that could be better are the wires, but they certainly aren't terrible. They bend easily but don't have the best appearance. ... show more

  • Should have never switched brands.
Size: 1200W Style: Dark Power 14
They're customer service is not great. I use a backup ups with all my computers/servers. They all have voltage regulation and if the voltage goes outside of a certain range, (89-144 volts) it kicks in the battery so it's not destroying my components over time. This Be Quiet psu is getting as high as 179v everytime I start the computer. This isn't a new build and this hasn't been a problem until I installed this power supply. Be Quiet told me that my back up battery is the issue and would not warranty the component without taking multiple weeks to do "tests". Time is money. Im not waiting multiple weeks for you to tell me what I already know. It's also not my responsibility to take even more of my time to take your defective product out send it to you and wait. Where is EVGA when you need them? ... show more
