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.


The first thing we are going to look at with the Thermaltake Toughpower GX1 700W 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 GX1 700W looks a lot like what we have been seeing from recent Thermaltake units. That means, the main feature of the packaging is a picture of the included unit along with a column of advertising blurbs on the side of the front of the box. These blurbs include things like "Ultra Quiet Fluid Dynamic Bearing Fan", "Low Ripple Noise", "105C Japanese Main Capacitor", "5 Year Warranty", and "80 Plus Gold". Out of that list, the 80 Plus Gold advertising goes well with the 80 Plus Gold seal we find on the box. When we check the 80 Plus website we do not find the unit listed but Thermaltake was able to provide the test report for the unit so this appears to be an issue with ECOS/ECOVA updating their database. Moving on, the 5 year warranty is not the longest we see these days but is certainly fitting for the product segment that this unit seems to be targeted at. When we move to the rear of the packaging, we find the power table (reproduced below), the connector count (reproduced below), and some advertising points about features of the unit. The remainder of the packaging does not turn up much more information than that.

The power information for the Thermaltake Toughpower GX1 700W indicates that the unit is a single 12v rail unit. This 12v rail has a capacity of 58A or ~99% of the unit’s total possible capacity if necessary. The minor rails are each individually capped at 22A with a combined capacity of 120W which is rather significant in this day and age. Coupled with these outputs we find four modified 8 pin PCIe connectors, eight SATA connectors, and four Molex connectors. Overall, for a 700W unit that is not supposed to be a top of the line product, this unit should be capable of physically supporting the vast majority of systems that users would likely put it in these days with great ease.

Once we open the Toughpower GX1 700W packaging, we find the power supply, mounting screws, the power cord, zip-ties, the user manual, and a product warranty guide. As before, the product warranty guide starts off with the length of warranty, but instead of listing that length it tells you to visit Moving on to the user manual, we see that the user manual is a single piece of paper folded like an accordion and then in half. On this piece of paper we find connector counts and power labels for the 500W, 600W, and 700W models along with some installation steps, a few troubleshooting steps, and a few basic electrical specifications. All in all, the user manual is rather light on important information. Let's move on now and look at the actual power supply itself.
