SilverStone DA1650

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 1650W 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 big daddy of them all the DA1650 (SST-DA1650-G) which is the largest capacity product in SilverStone’s Decathlon series. 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 Giant Among Mere Mortals?

The SilverStone DA1650 is the sixth power supply we have seen from SilverStone as well as the absolute largest capacity unit we have seen from SilverStone or anyone else for that matter. This particular high wattage unit is probably a bit more interesting than most power supplies we see simply because of just how big it is capacity wise. At 1650W DC output, this unit is going to be one of the largest capacity power supplies you are likely to see in the ATX12v/EPS form factor in North America. This just might be the power supply a lot of you are looking towards though with the new power demands on GeForce RTX 3090 and GeForce RTX 3080 video cards.

We have had a few 1600W commercial products before this and even a few oddballs that would do more than 1600W if fed from 230/240v input (like the Enermax MaxRevo 1800W) that have been available in NA, but this one takes the cake currently. Beyond that, this is a bit outside of SilverStone’s usual wheelhouse so we certainly are interested in seeing how it will fare. However, before we get to far ahead of ourselves, let’s first see what SilverStone has to say about this unit:

■ High efficiency with 80 PLUS Gold certification ■ 24/7 continuous power output with 50℃ operating temperature ■ 100% modular design with universal EPS / PCIe connector interface for maximum flexibility ■ Ultra silent 135mm FDB fan with semi-fanless and delayed shut-off function ■ Strict ±2% voltage regulation and low ripple & noise ■ All Japanese capacitors

Let’s move on now and see what we can expect when a user purchases the SilverStone DA1650 power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
