GSX I™ – PCIe Bitcoin Mining Card


CoinTerra’s GSX I is a high-performance, affordable PCI Express mining card that sets a new standard in performance and price for Bitcoin mining enthusiasts, hobbyists and system builders.

At the heart of the GSX I is CoinTerra’s GoldStrike™ I ASIC processor mated to CoolIT’s DCLC™ direct contact liquid cooling unit with a 120mm exhaust fan. The GSX I package is designed to fit a wide assortment of PC mid-tower and full-tower cases, enabling the seamless integration of a dedicated high-performance Bitcoin mining processor into a standard PC form factor.

The GSX I is controlled by the same software as the TerraMiner, running on the host PC and connected via the card’s USB ports. This architecture allows for maximum flexibility, including the possibility of building expandable mining solutions with non-PC controllers.

The GSX I is now available for pre-order with delivery scheduled for June 2014.

SKU: GSX-111.
