Thermaltake Toughpower GX1 700W Power Supply Review

Thermaltake is no stranger to HardOCP when it comes to making Toughpower PSUs. We have used these for years ourselves. The newest Toughpower is part of Thermaltake's GX1 series. This GX1 700 watt unit touts Gold level efficiency, a fluid dynamic bearing fan, and is oddly not modular in any way, which is something very unusual in today's market.


Today, Thermaltake Technology Company is back for another trip through our power supply testing program with a more value oriented product than we last saw from them. As a company, Thermaltake has a rather short history being founded in just 1999, but in that short time they have grown rapidly. While Thermaltake's primary focus has been on thermal solutions, it has for some time now maintained a group of product lines dedicated to power supplies. The early power supplies in these lines were often of lower quality but over the years they have taken their power supply business in a new, and quite frankly better, direction as they paired with higher quality OEMs like CWT and Enhance. Today, we are looking at a product that is part of the Toughpower Series of power supplies from Thermaltake; the Toughpower GX1 700W (SP-700AH2NCG but also variously listed as PS-TPD-0600NNFAGx-1, etc depending if you look for the model or part number). This unit is produced in conjunction with CWT.

Channel Well Technology (CWT) was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, Thermaltake, Xigmatek, and Corsair. While most familiar to our US users from when it used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as it has a fairly high level of vertical integration providing transformers all the way up to its well designed independently regulated SMPS. Recently however, CWT has begun stretching out and is providing OEM services for a number of brands as today’s unit demonstrates.

Toughing It Out in the Mainstream

The Thermaltake Toughpower GX1 700W is the latest in a very long line of power supplies that we have seen from Thermaltake. It is also a bit different from many of the products we have seen from Thermaltake as this unit seems to be much more about the mainstream and value minded customers unlike the large number of 1200W beasts we have seen from Thermaltake. Obviously, the kind of users looking for this product (and the market that this product will be right for) is completely different from the ones looking for those 1200W+ monsters. However, the side of the box still says Thermaltake and that means that users will still have many of the same kinds of expectations even when they are buying something lower down the totem poll. Before moving on to find out if the Toughpower GX1 700W can live up to those expectations, let's see what Thermaltake has to say about this unit and this difficult proposition:

Built to deliver 80 PLUS Gold efficiency, Toughpower GX1 comes with capacities ranging from 500W to 700W, and the application of 120mm Fluid Dynamic Bearing Fan, <+/- 3% tight voltage regulation, Japanese 105C/221F main capacitors and premium components. Its near silent operation, trouble free installation and reliable performance are making itself one of the best values for basic system upgrades.

Since none of that is a surprise given this units placement in Thermaltake's lineup, let's take a look at what we get when we purchase the Thermaltake Toughpower GX1 700W power supply in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
