SilverStone Strider Platinum ST1000-PT PSU Review
In today's world of PC hardware, it is not exactly easy to build a system worthy of needing 1000 watts of power, but if you happen to be doing that, the SilverStone Strider Platinum series has a solid unit that likely fits your budget while ticking off all the high end check boxes, especially efficiency.
The first thing we are going to look at with the SilverStone ST1000-PT 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. 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 of the SilverStone ST1000-PT is very similar to what we have seen from previous members of the Strider Platinum line (ST75F-PT and ST55F-PT). The main features we see on the front of the packaging are a large "platinum" portion and a superimposed picture of the ST1000-PT. In addition to this, we see some advertising about various features of the unit including "100% Modular Cables", "139mm Air Penetrator Fan With Intelligent Semi-Fanless Operation", "Strict 3% voltage regulation and low ripple & noise", etc. Beyond that, we also see a 80 Plus Platinum logo and when we check the 80 Plus website we do find that this unit is certified for that level of efficiency. When we flip to the rear, we see the same advertising points reprinted in a number of different languages. We also see the same advertising points expanded upon in pictorial and graphical form. When we move to the sides, we find the power table (reproduced below) and the connector counts (reproduced below). One of the things of note that we don't find is the warranty length. After a bit of poking around, we find that the warranty on this unit is 5 years. As you might remember, a little while ago SilverStone increased their warranty length on certain product lines from 3 years to 5 years and the ST1000-PT is one of those units that has benefited from that change.
The power information for the SilverStone ST1000-PT is similar to what we have seen with other modern 1000W power supplies. The ST1000-PT has a 12v capacity of 83A (or ~99.6% of the unit’s total possible capacity if necessary). When we look at the minor rails, we notice a problem. The packaging indicates that the minor rails are capped at 120W total with the individual capacity of each minor rail being 22A. However, the power label in the unit itself indicates that the cap on the 3.3v rail is 25A and the 5v rail cap is 22A. Then, the power table on SilverStone's website (seen above in white) indicates that the 3.3v capacity is 22A, not 25A, and the 5v rail has a cap of 25A! We literally get three different power output ratings for this unit from three different sources. Something seems to be amiss somewhere. That said, most users aren't going over 22A on the 5v or 3.3v rail, but it would be nice if the right values were consistently listed in the specs. Moving on to the connectors paired with these output capacities, we find that the SilverStone ST1000-PT has six modified 8-pin PCIe connectors, six Molex connectors, and sixteen SATA connectors. That arrangement is a certainly adequate and, in fact, is rather robust when it comes to SATA connectors. So, users who are looking for big peripheral connection options this unit seems to have that well in hand today!
Once we open the ST1000-PT packaging, we find the unit, cables, power cord, mounting screws, some zip ties, some Velcro straps, a fan filter, and the user manuals. One of the manuals that comes with this unit is 7 pages long in English only. The other is a booklet of installation instructions, pinouts, power label, installation instructions, some troubleshooting steps, very complete electrical specifications, and warranty information that we see with just about every SilverStone unit written in 11 languages that cover the cover the ST1200-PT and the ST1000F-PT. As we have stated before in other reviews of SilverStone products, we have to continue to commend SilverStone for including very complete electrical specifications with their powers supplies. Most brands these days do not show nearly this amount of effort or pride or transparency in their power supply offerings. So, when we see such things from SilverStone it is greatly appreciated. Let's move on to the unit itself now.
