SilverStone Strider Gold S ST85F-GS 850W PSU Review

Good things come in small packages and SilverStone continues its Gold S series with smaller fully modular footprints at the 850 watt power level. SilverStone claims Gold level efficiency, tight voltage regulation, a single rail design, low fan noise, and plenty of PCIe outlets. All the things that SilverStone is famous for.

Overview

The first thing we are going to look at with a Strider Gold S 850W power supply is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help in many situations. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there are cases where a manufacturer can include useful accessories to make installation, routing and use more efficient.

The packaging for the Strider Gold S 850W (ST85F-GS) is trimmed out identically to what we saw from the recent ST75F-GS. As such, we again see that this unit is certified for 80 Plus Gold efficiency, it has strict 3% voltage regulation, it is rated at 40C operating temperature, and that it has a "silent running 120mm fan with 18dBa minimum." The 80 Plus efficiency level is quickly found on the 80 Plus website and we will of course check in on this later. When we move to the back of the packaging, we find an efficiency graph and a fan noise graph along with a number of marketing points that we have seen before. Moving to the sides of the packaging, we find the power and connector counts for the 750W and 850W models (850W figures are reproduced below). Given that it has just been a few short weeks since we saw the ST75F-GS, it is of no real surprise then that we still do not find clear warranty information for this unit. However, the warranty information is the same as was found on the ST75F-GS. (You can again find it here.)

When we look at the power table for the ST85F-GS, we again see a modern power supply with a strong 12v rail just like we saw with the ST75F-GS. The ST85F-GS has a total 12v capacity of up to 70A or ~99% of the unit’s total capacity if necessary. In addition to this, the unit features the exact same minor rail capacities as the ST75F-GS with 5v and 3.3v capacities of up to 22A (3.3v) and 25A (5v). Coupled with this output, we find that the ST85F-GS has the same connector options as what was found on the smaller ST75F-GS. This includes a total of 4 PCIe connectors, 6 Molex connectors, and 8 SATA connectors. Given that these are the exact same values we saw from the recent ST85F-G Evolution, we can’t complain. However, with these also being the same as what we saw on the ST75F-GS we have to come to the conclusion that someone is either under delivering or over delivering in connection options as there is a 100W difference in capacity for the same connector counts.

Once we open the ST85F-GS packaging, we find that the box includes the unit, cables, power cord, mounting screws, some zip ties, some Velcro ties, and user manuals. One of the manuals that comes with this unit is 10 pages long in English only and the other is a single page folded over many times in 11 languages. Among this documentation, we find the pinout guide, power label, installation instructions, some trouble shooting steps, and the very complete electrical specifications. (Actually the most complete we see from any vendor these days.) As we have stated before, one of the things we don’t find normally is the warranty length, we do find some of the warranty stipulations though.
