Known for coming up with innovative new high-end non-reference graphics cards for overclocking, ZOTAC is treating the GeForce GTX 580 GPU to a strong VRM and cooling to aim to be every overclocker's desire. To begin with, the card uses a strong 18-phase VRM to power the GTX 580. Power is drawn from two 8-pin power connectors, and is conditioned by the VRM that occupies a large part of the PCB including the rear portion and a top portion that's protruding above the full-height limit. The VRM uses high-grade MOSFETs, server-class capacitors, and proadlizers to condition power. The source notes that the VRM can handle up to 500W load.
To cool the beast, there are two heatsinks, first is the component heatsink that is spread across the length of the card, cooling VRM and memory; and the primary heatsink, which is a massive aluminum fin array to which heat is fed by six 6 mm thick heat pipes. The heatsink is ventilated by two 120 mm fans. The card is overclocked out of the box, with the core running at 850 MHz, 1700 MHz CUDA cores, and 1100 MHz (4.40 GHz effective) memory. Display connectivity includes two DVI and one each of HDMI and DisplayPort. You can use two connectors at a time. There's no info on pricing and availability, though ZOTAC is known for releasing such specialty products in Asian markets only.
