Description

This Cooler Master brand power supply unit has an 80 PLUS Gold energy efficiency certificate and a power output of 850W.

This 850W power supply unit is intended for a workstation or high-performance gaming computer. It will be able to power multiple hard drives (SSD/HDD), water cooling, a high-end graphics card (for example, RTX 4070 Ti SUPER), and a top-tier processor (possibly overclocked).

The diameter of this power supply unit's fan is 120 mm, which will ensure quiet operation in mid-range computers. For especially quiet power supply unit operation, we recommend selecting a fan with a 135 mm or 140 mm diameter.

The power supply has received the 80 PLUS Gold energy efficiency certificate, which guarantees at least 90% efficiency at 50% load. This means that for every 100W of power received from the electrical grid, at least 90W is delivered to your computer components, and the remaining 10W is lost as heat.

The color of this power supply is Melna. The cable color is Melna and they are flat.

This power supply unit has fully-modular cables (Fully-modular) – you can connect and disconnect all the included cables as needed, reducing clutter and improving ventilation. This will be useful for those with a partially transparent computer case and for whom the aesthetic factor is particularly important.
