SilverStone Strider ST1500 1500W Power Supply Review

SilverStone raises its flagship Strider PSU to what is the near-limit of wattage you can pull out a normal North American wall plug. At 1500 watts continuous and 1600 watts peak this power supply will hopefully get the job done for you. Let's see how it holds up under full load.


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 their power supplies which are comprised of the Strider, Decathlon, Element, Nightjar, Zeus, Gemini, and Olympia model lines that range from 350W to 1500W DC output. Today, we are looking at the largest capacity unit from SilverStone's Strider series (or any other series really), the Strider 1500W (SST-ST1500) which comes from Enhance.

Enhance Electronics Co. Ltd. was founded over 20 years ago in 1986. While a major power supply OEM Enhance is not nearly as well known to most users as some other OEM's as its core business focus has been outside of the desktop market in areas such as servers, embedded, and telecom markets. However, its products have started to surface in the US consumer realm in the last year or so under the likes of SilverStone, Silverpower, Antec, and now Cooler Master as well as the occasional Enhance branded model. Today's SilverStone Strider 1500W represents the largest capacity power supply we have seen from Enhance to date.

1500W Heavyweight Champion?

The SilverStone Strider ST1500 we have in today is the 6th SilverStone power supply we have seen to date, and second from its Strider line. The last Strider unit we saw though was almost 1/4 of the capacity of this unit as it was the entry level ST400. Today's ST1500 then is quite literally on the opposite end of the spectrum from that unit and also represents the largest capacity unit that SilverStone currently markets from any of their product lines. In our previous reviews of SilverStone products we have seen a number of high powered units, well three 1000W units to be exact, and we have yet to have any serious issues with these products. However, this unit is pushing the envelope of what we will find supported in North America at 120v input so we have to wonder if it is also pushing the envelop of what SilverStone's and Enhance's designs can support. Before moving on let's see what SilverStone has to say about this unit:

Reaching 1500W DC output (1600W peak), the Strider ST1500 is effectively at the limit of what an internal PC power supply can achieve in terms of wattage rating. For SilverStone, getting to this maximum power was only part of the goal for a consumer-level power supply so every desirable feature known were added to create a dream product. The list starts with unprecedented eight +12V rails with each capable of up to 25A and continues with features such as 100% modular cables, 80 PLUS Silver worthy efficiency ratings, and quietness level that matches most 500W PSUs. If there is one upgrade that will likely outlast a PC enthusiast's interest in computing, the ST1500 may just be it.

Moving on let's see what we can expect when a user purchases the SilverStone Strider 1500W at retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
