SilverStoneTek is a company best known for its high-quality cases but its 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-PT model number SST-SX700-PT which is one of SilverStone’s SFX (small form factor) 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.
A Little Giant Platinum Nugget?
The SilverStone SX700-PT is the fifth power supply we have seen from SilverStone as well as the second SFX unit we have seen from SilverStone here at TheFPSReview. This particular unit is probably a bit more interesting than the most recent SilverStone unit we saw (ST1200-PTS) as the SFX, fanless, and just unique markets are where SilverStone has been a star for years. Beyond that, it is coming in at the same power level as the other SFX unit we have seen from SilverStone, the SX700-G, giving us a very nice comparable product to judge this one off of today. As this product is coming to us from what is SilverStone’s wheelhouse, we have great expectations from this tiny power supply. However, before we get to far ahead of ourselves, let’s first see what SilverStone has to say about this unit:
￭ Support standard SFX form factor ￭ Silent running 92mm FDB fan with 18 dBA minimum ￭ All Japanese capacitors ￭ High efficiency with 80 PLUS Platinum certification ￭ Class-leading single +12V rail ￭ Strict ±3% voltage regulation and low ripple & noise ￭ 100% modular cables ￭ All cable with flexible flat arrays
Let’s move on now and see what we can expect when a user purchases the SilverStone SX700-PT power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
