After showing off a monstrous DirectCu II cooled Radeon HD 6970 at CES, ASUS released pictures of another card which probably couldn't make it to Vegas. The GeForce GTX 580 DirectCu II from ASUS is just as beastly as its Radeon cousin. It uses a completely in-house design, with custom PCB that uses a strong VRM; and a triple-slot cooler which uses copper heatpipes that make direct contact with the GPU. The PCB uses an 8-phase vGPU VRM, it draws power from two 8-pin power connectors. The power circuit is also completely localized, meaning that it draws absolutely zero power from the PCI-Express slot. The VRM makes use of high-grade components, including an NEC-made proadlizer to condition power for the GPU.
The DirectCu II cooler uses a large aluminum fin array to which heat is conveyed by five heatpipes that make direct contact with the GPU. Two 100 mm fans are in charge of ventilation. The rear panel consists of two DVI, and one each of DisplayPort and HDMI. The card is bound to have factory overclocked speeds, with room for more overclocking. The cooler, though large and with two fans, is tested by the company to be quieter than NVIDIA's reference design cooler. The GeForce GTX 580 is NVIDIA's flagship DirectX 11 GPU. It packs 512 CUDA cores, and connects to 1536 MB of memory over a 384-bit wide GDDR5 memory interface.
