Thanks to LLC topology, the Pure Power 13 M 850W offers first-class voltage regulation. Therefore, it is the best choice for building very quiet systems, as well as upgrading gaming PCs and media editing.
Pure Power 13M 850W is an ATX 3.1 power supply and comes with a 12V 2x6 connector for Next-Gen PCIe 5.1 graphics cards and 4 PCIe 6+2 ports for current graphics cards. This makes the Pure Power 13 M 850W extremely versatile and the perfect choice for all current and future-proof high-end systems.
Pure Power 13 M provides 850W of continuous power on a solid 12V line. Even if the graphics card retrieves excessive performance over short periods, the Pure Power 13 M 850W can handle peak loads up to twice the rated load without any problems. This ensures reliable operation with the next generations of processors and graphics cards.
Only the cables that are really needed are used! Laying the cables is very easy with the Pure Power 13 M 850W. The advantage: a tidy chassis and undisturbed airflow that leads to lower system temperatures and overall quieter operation.
At low load, the fan switches off completely until it is used again for more demanding applications. A re-ventilation phase of 2-5 minutes during cooling prevents frequent and annoying starts and stops of the fan. In combination with the large fan, this power supply is exceptionally quiet in all scenarios.
