Description

Available for purchase is a power supply produced by Be Quiet with a power output of 850W. The product has been awarded an 80 PLUS Gold energy efficiency certificate.

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 the block is Melna. The block has flat cables, whose color is Melna.

This is a power supply that complies with ATX 2.0 requirements. The power supply has only 6-pin and 8-pin connectors, which can handle only 75 W and 150 W of power, respectively. Modern graphics cards' high power needs exceed the capabilities of ATX 2.0 connectors. When building a system with a very powerful GPU, such as an RTX 4070, you will need an ATX 3.* standard power supply.

This power supply has no removable cables and all cables are attached to the power supply. It has a simple design, but it works just as well as a power supply with modular cables.

This power supply manufacturer is Be Quiet. See all Be Quiet power supplies here.
