Description

This Gigabyte brand power supply unit has an 80 PLUS Gold energy efficiency certificate and a power output of 850W.

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).

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.

80 PLUS Gold energy efficiency certificate received by this power supply guarantees at least 90% efficiency at 50% load. In other words, for every 100 W of energy the power supply receives from the power grid, at least 90 W goes to your computer components, and the remaining 10 W is lost as heat.

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

This power supply unit has been assigned the ATX 2.0 standard. This means that the unit is equipped only with 6-pin and 8-pin connectors, providing 75W and 150W power respectively. It's important to note that this unit will be compatible with RTX 4070 and more powerful cards, but you will need to use the 2x8-pin to 16-pin 12VHPWR adapter included with the graphics card. ATX 2.0 power connectors are not designed to handle the high power fluctuations of modern graphics cards; therefore, if you are building a system with a powerful GPU, such as the RTX 4070, we recommend choosing a power supply unit with the ATX 3.* standard and 12VHPWR (PCIe 5.0) connector.

The power supply unit has received the Cybenetics Standard ++ noise level certificate – the noise generated by the unit will be 30-35 decibels.

This power supply unit has fully-modular cables (Fully-modular) – you can connect and disconnect all the included cables as needed, reducing clutter and improving ventilation. This will be useful for those with a partially transparent computer case and for whom the aesthetic factor is particularly important.

This power supply unit is manufactured by Gigabyte. You can view all Gigabyte power supply units here.

LongDesc - Inherit the product design spirit of GIGABYTE Ultra Durable, thus introducing a variety of high-quality materials and designs. Ultra Durable combines high-quality main Japanese capacitors, enhanced thermal solution, 120mm smart hydraulic bearing (HYB) fan, and six circuit protection designs. It provides consumers with a high-quality and stable power supply, and can be used for a long time.HIGH QUALITY JAPANESE CAPACITORSThe main capacitors use high quality Japanese capacitors to produce the efficient performance and ensure the longer reliability.ENHANCED THERMAL SOLUTIONCompared with the standard thermal solution, we have enlarged the heatsink by about 200% or more, and optimized the airflow. The heat dissipation performance is increased by more than 10%, thus prolonging the service life of the components.120MM SMART HYDRAULIC BEARING (HYB) FANThe fan speed is adjusted according to the automatic power detection and stops when the system is idle or under low load (less than 20% load). The hydraulic bearing fan provides longer and more stable life time.PROTECTIONIn order to make sure the entire computer system to operate stably under any conditions, we not only added protection designs such as OCP, OTP, OVP, OPP, UVP and SCP, but also ensured the stable operation of your system through the safety certification of various countries.FULLY MODULAR DESIGNAll the black flat cables are modular design. Installing only the cables you need to reduce clutter, to increase the airflow and to improve the chassis thermal performance.
