Thermaltake DPS G 1050W Platinum Power Supply Review

While this computer PSU's marketing skips right to the green-speak, it is feature packed in terms of hardware and software, but as always we want to know what it does when it is under load and serving up the over 1 kilowatt of power that it promises on its label also claiming exceptional efficiency while it is doing it.

Overview

The first thing we are going to look at with the Thermaltake Toughpower DPS G 1050W Platinum 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 Thermaltake Toughpower DPS G 1050W Platinum changes things up a bit from what we have seen from our most recent Thermaltake units including the DPS G 650W. The main feature of the packaging is a picture of the included unit along with a column of marketing points on the left side. Among these advertising points, half of these pertain to the digital monitoring of the unit that we will cover in an article separate of this review. One of the other points is the use of FlexForce style cables and the last is the fact that this unit is covered by a 7 year warranty which is fitting for a flagship type of product. Lastly, we see a singular seal at the bottom of the package indicating that the unit is certified for 80 Plus Platinum. A quick check of the 80 Plus website does indeed find the unit listed. A little later on we will see how this unit actually compares to that criteria. When we move to the rear of the packaging, we find the power table (reproduced below), the connector count (reproduced below), some advertising points, an efficiency graph, and a fan noise graph. The remainder of the packaging does not turn up much more information than that.

The power information for the Thermaltake Toughpower DPS G 1050W Platinum indicates that the unit is a single 12v rail power supply. This 12v rail has a capacity of 87A or ~99% of the unit’s total possible capacity if necessary. The minor rails are capped at 22A for the 5v rail and 25A for the 3.3v rail. Combined, they have a total capacity of 120W. Coupled with these outputs we find eight modified 8 pin PCIe connectors, twelve SATA connectors, and eight Molex connectors. This allotment of connectors is very similar to what we have seen from the most recent 1200W products from Thermaltake and, overall, this distribution should be sufficient for 99% of users looking at a 1200W power supply let alone a 1050W power supply.

Once we open the Toughpower DPS G 1050W Platinum packaging, we find the power supply, modular cables in a pouch, the USB header cable, mounting screws, the power cord, the user manual, and a product warranty guide. The user manual is a single piece of paper folded like an accordion and then in half as we have seen from a number of Thermaltake units now. On this piece of paper we find connector counts and power labels for the members of this line along with some installation steps, a few troubleshooting steps, and a few basic electrical specifications. As before with this setup, the user manual is rather light on important information and that is somewhat disappointing as this is clearly supposed to be a higher end product. Let's move on now and look at the actual power supply itself.
