Sea Sonic and HashFast Sign Deal To Power Next Generation of Bitcoin Mining Equipment

October 18, 2013

SAN FRANCISCO  —  Sea Sonic Electronics Co. Ltd (‘Sea Sonic’) and HashFast Technologies LLC (‘HashFast’) announced today that they have signed an agreement for Sea Sonic to produce power supplies for HashFast’s Bitcoin mining systems.

The Baby Jet and Sierra mining units will be built using Sea Sonic power supplies, which are widely known for their industry-leading efficiency, quality and reliability. The highly stable output voltage from Sea Sonic supplies ensures the miners will consistently reach their maximum hashing performance. The very high efficiency of these supplies lowers the electrical costs involved in mining, and reduces the waste heat produced.

Tests of the Sea Sonic power supply show an incredibly stable output and longevity, even when machines are overclocked, enabling miners to generate more Bitcoin for their money.

“We believe mining rigs should come complete with the best power supplies available” said HashFast CEO Eduardo de Castro. “The quality and reliability of the power supply has a critical effect on the performance of Bitcoin mining equipment.  It’s well known that Sea Sonic is a clear leader in the power supply industry, and their products are widely known for their build quality, efficiency and reliability. Their reputation for quality extends over nearly four decades.”

Sea Sonic President Vincent Chang agreed with the emphasis on quality, noting that “Quality is something that is of paramount importance to us at Sea Sonic.  We have been in the industry for over 38 years and pride ourselves as being a leader in manufacturing highly stable, reliable and energy efficient power supplies.”

He further added that “It is an honor to support HashFast producing the highest quality and most efficient Bitcoin mining equipment possible. We look forward to a future in which our companies work together to provide the best possible products and services in the industry.”

“It is a great honor to be working with Sea Sonic,” said de Castro. “We look forward to a long and fruitful relationship.”

About HashFast Bitcoin Mining ASICs

Hashfast GN 28nm HPM Bitcoin mining ASIC was announced in July and taped out on schedule on August 28, 2013.HashFast’s Golden Nonce (GN) is a 28nm ASIC chip that performs 400 Ghash/s at nominal clock speed and consumes less than 0.65 W/GH. It can be underclocked for greater efficiency and overclocked for greater performance. The chip has on-die thermal controls to allow operation at its absolute maximum performance.  This equipment is solely intended for use in commercial environments. Power consumption figures are from simulations, and may be +-20% in real silicon.
