Technical data / specifications

With the DirectCUII ASUS has the first high-end NVIDIA 500-series graphics card in its portfolio that features an improved power design as well as a new cooler. This card can rely on eight phases and to furhter improve reliability ASUS provided the different components like coils, capacitors, POSCAPS and MOSFETs with an alloy which should keep them cooler and therefore improve the components lifespan. One can also find two 8-pin power connectors. The message ASUS sends out, especially with the two 8-pin connectors, is quite clear and aims at extreme overclocking.
Another key component with this card is the DirectCUII cooler which also is a design by ASUS and has been equipped with two 100 millimeter fans. You also find five heatpipes with a diameter of eight millimeter. According to ASUS this cooler should work much more efficient than the reference model. In reality we see that when the card is in idle mode it is just a little bit noisier then the reference but under heavy load conditions it's not only working more efficient it is also way more silent.
Looking at the clock speed we can see that the GTX580 DirectCUII comes with a 10 MHz overclocking on the GPU which is almost standard with ASUS graphics cards these days.
