SilverStoneTek is a company best known for its high quality cases but their product lines extend into other components such as cooling, power supplies (of various model lines that range from 300W to 1350W in DC output), fans, and storage solutions. SilverStone has built up this impressive product repertoire since its founding in 2003. For this review, we are looking at the SX700-G which is one of SilverStone’s SFX products. It is produced in conjunction with Sirfa.

Sirfa Electronics Co., Ltd. is a name that is not that familiar to most users but Sirfa has been around since 1996 when Sirtec established Sirfa as a factory in the Sirtec group on mainland China. In June 2008, Sirtec sold off its interest in Sirfa making the company independent of the Sirtec brand but still in business with High Power. As such, while we have not seen any Sirfa produced power supplies under the Sirfa brand, some of the Sirtec units of the past were produced at the Sirfa facility. Additionally, we have seen Sirfa providing OEM services for Thermaltake, Enermax, PC Power & Cooling, Tuniq, Lepa, SilverStone, and others with mixed results.
