Description

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

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

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.

Thanks to the fact that this power supply has modular cables, you can add hard drives, video cards, and other components as needed, using the various cables included in the package. This way, there are fewer wires in the computer, which improves ventilation and appearance (especially useful for those who choose a partially transparent case).

This power supply has an SFX (Small Form Factor eXtended) type. Although it does not have as large size and power as AFX type supplies, it will be suitable for small form factor (SFF) computers. The power supply works with system boards like Mini-ITX, and it has smaller fans.
