Description

This Lian Li brand power supply unit has an 80 PLUS Platinum energy efficiency certificate and a power output of 1200W.

This power supply is equipped with an exceptionally large 135 mm fan. Thanks to the larger blade size, it provides better airflow at lower speeds and quieter operation compared to standard 120 mm fans.

The power supply has been awarded the 80 PLUS Platinum energy efficiency certificate, which ensures at least 92% efficiency at 50% load. This indicates that at least 92 W out of 100 W of power that the power supply receives from the power grid is delivered to the computer components, while the remaining 8 W is lost as heat.

The color of the power supply is Balta. It is equipped with flat cables, whose color is Balta.

The noise level of this power supply is 20-25 dB and it has a Cybenetics A noise level certificate.

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).
