Description

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

850W power supply will be suitable for a powerful workstation or gaming computer. It will provide power for a high-end video card (for example, RTX 4070 Ti SUPER), multiple hard drives (SSD/HDD), water cooling, 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.

ATX 2.0 standard, which is assigned to this power supply unit, ensures that the unit is equipped only with 6-pin and 8-pin connectors (with respective power of 75W and 150W). For a system with a very powerful graphics card (such as RTX 4070), an ATX 3.* standard unit will be required, and ATX 2.0 will not be sufficient.

This power supply unit uses semi-modular cables. It has cables attached to the unit, and others that can be added or removed as needed. We recommend such power supplies for those who do not want a fully modular system but desire some flexibility.

Description - The G12 GM Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic G12 GM-Series achieves 80 PLUS® Gold standard of providing at least 87 %, 90 % and 87 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the G12 GM series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the G12 GM units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC). 80 PLUS GOLD
The G12 GC achieves 80 PLUS Gold certification with its 90 % efficiency at 50 % system load. S2FC - SMART AND SILENT FAN CONTROL
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.ATX 12 VSemi-modular cables80 PLUS Gold Certified140 mm (L) x 150 mm (W) x 86 mm (H)
