Description

We offer to purchase a Seasonic power supply unit with a power capacity of 850W, which has received the 80 PLUS Gold energy efficiency certification.

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).

This power supply unit is equipped with a 120 mm fan, which is the industry standard for ensuring quiet operation in average computers. If you want an especially quiet unit, look for one with a fan diameter of 135 mm or 140 mm.

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.

This power supply's noise level is 25-30 dB and it has a Cybenetics A - noise level certificate.

This power supply has modular cables, which provide the possibility to add video card cables, hard disk cables, etc. as needed from the supplied range. This way, the wire clutter in the computer is reduced, improving ventilation and the aesthetic factor (particularly important for those who purchase a partially transparent case).
