Description

Available for purchase is a power supply produced by Asrock 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 been awarded the 80 PLUS Gold energy efficiency certificate, which provides at least 90% efficiency at 50% load. This indicates that at least 90 W out of 100 W of power drawn from the electrical grid by the power supply is delivered to the computer components, with the remaining 10 W lost as heat.

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

The power supply unit does not have modular cables; all cables are attached to the power supply unit and are not removable. Despite this, it will work just as well as a power supply unit with modular cables.
