SilverStoneTek is a company best known for its high quality cases but its product lines extend into other components such as cooling, power, fans, storage, and so on. As a company, Silverstone has built up this impressive product repertoire in a very short time having been founded in 2003. Today, however we are interested in its power supplies which are comprised of the Strider, SFX, Nightjar, Gemini, and Zeus model lines that range from 300W to 1350W DC output. For this review, we are looking at a revision to one of SilverStone’s smallest capacity SFX series power supplies, the ST30SF V2.0, which 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 very mixed results.
Today, SilverStone is back with another entrant in the SFX power supply market. This is, perhaps, not a huge surprise as SilverStone has been one of the most prolific vendors in this market that we have seen. Now, today's ST30SF V2.0 is, however, not only the smallest capacity SFX unit we have seen from SilverStone but also the smallest capacity unit we have seen in general. This is interesting as small capacity units are actually a much better fit for the majority of SFX applications than what we have seen with 600W type offerings. So, today, we have a unit that is the right form factor and the right capacity for most small builds. On top of that, this unit has a pedigree, coming from SilverStone, that is perfect for this market as well. So, before moving on to see if this all does come out as good as it seems, let's see what SilverStone has to say about this unit:
As the standards bearer of SFF (small form factor) cases and SFX PSUs, SilverStone has released a reference power supply design for the masses in the ST30SF, a 300W SFX unit designed with high affordability and great performance. It has 80 PLUS Bronze efficiency and a silent running fan for class leading efficiency and low noise.
To enable users to easily take advantage of this excellent SFX power supply, an adapter is included to convert ST30SF to mount in any ATX case in addition to ones that fit only SFX. For SFF users, the ST30SF is an excellent, well-rounded power supply for any DIY desktop computer.
V1.0 has greater +3.3V and +5V output and higher temperature rating of 10℃ ~ 50℃ for NAS/storage focused systems or industrial PCs (IPC).
V2.0 has greater +12V output and lower noise for home desktops or gaming PCs.
Let’s move on and see what we can expect when a user purchases the ST30SF V2.0 power supply at retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
