SilverStone ST80F-TI 800W Power Supply Review

SilverStone and its Strider series of computer power supplies have been almost perfect when it comes to earning HardOCP awards. Today it comes to us with a fully modular Titanium efficiency rated 800 watt PSU that it claims to be the world's smallest in this category. "413 watts per liter!" Let's see how that works out today.


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 1500W DC output. For this review, we are looking at SilverStone’s newest addition to the Strider line, the ST80F-TI , which is produced in conjunction with 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 OEMs 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, Cooler Master, and Thermaltake, as well as the occasional Enhance branded model.

An Efficient Gait Stride?

Today's Strider STF80-TI is the newest revision in SilverStone's Strider line of power supplies. Over the last 8 years, we have seen a number of members of the Strider line of products from SilverStone. We have seen Strider units as small as 400W and as large as 1500W. We have seen these units range in physical size from very large to very small. We have seen units that range from fairly efficient to extremely efficient. In all that time, and those various permutations, we have consistently seen Strider units that have largely been very good products. Obviously, a long history of quality performance leads us to expect more and more from new additions. Today's ST80F-TI, therefore, is going to have its work cut out for it. At a minimum, we would hope to see the ST80F-TI do a bit better than previous units in the line. So, how exactly is SilverStone pitching the ST80F-TI you ask? Well, let's see:

Introduced in 2012, the 80 PLUS Titanium represent the pinnacle of power supply efficiency with requirement of at least 90% conversion efficiency even at the very low 10% loading condition. This stringent standard makes mass producing 80 PLUS Titanium certified power supplies below 1000W extremely challenging. However, as a leader in power supply miniaturization, SilverStone successfully mass-produced a new line of power supplies ── the Strider Titanium series. Their compact design makes them the world's smallest fully modular ATX power supplies with 80 PLUS Titanium efficiency. Other enthusiasts features included are all Japanese capacitors, آ±3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. For those looking to build the most efficient systems possible with great quality, the Strider Titanium is definitely the top choice.

Right off the bat, we see that SilverStone is expecting these units to be more efficient than anything else we have seen from SilverStone in the past, so that certainly plays into the "a bit better than previous units" area nicely. Beyond that, much of this sounds like things we have heard about previous Strider units from SilverStone but we are hopeful to see other incremental improvements as well. With that preview of what SilverStone expects from the ST80F-TI out of the way, let’s move on and see what we can expect when a user purchases the ST80F-TI power supply at retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
