Award-winning DirectCU II design continues to bring cooler and quieter operation to each generation of graphics cards. DirectCU II continues to combine the efficiency of direct contact copper heatpipes with the GPU, massive heatsink, and two fans to dissipate heat quickly. With different demands for power and temperature, ASUS exclusive DirectCU II now comes in a variety of flavors to bring at least 20% cooler performance while maintaining a standard in quiet operations.

The ASUS GeForce GTX 780 DirectCU II OC graphics card features a 10mm heatpipe instead of the conventional 8mm width. This particular variation boosts overall heat dissipation by up to 40% compared to the reference design, delivering 30% cooler and three times quieter operation.

The application of DIGI+VRM integrates a 10-phase power design to use digital voltage regulators to minimize power noise level by 30% and enhance power efficiency by 15%. DIGI+VRM is designed with wider voltage modulation tolerance to improve overall stability as well as increase overclocking potential.

The CoolTech fan moves air downward and outward with its dual, integrated blade design offering wider and more consistent airflow to maintain cooler and quieter operation.

Included backplate provides protection and support while increasing heat dissipation from the PCB.
