Thermaltake Toughpower Grand RGB 750W PSU Review

Thermaltake over the years has built some extremely good computer power supply units and along with that, it has also charged a premium for those which sometimes put it at a severe disadvantage in the value department. That changes today, in a very good way. It has flashy spinny LEDs, which you can turn off easily. And a 10 year warranty.

Overview

The first thing we are going to look at with the Thermaltake Toughpower Grand RGB 750W 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 Grand RGB 750W looks a lot like what we saw with the DPS G RGB 850W. So, once more, the main feature of the packaging is a picture of the included unit along with a column of advertising points on the left side. Among these advertising points, we see things such as "Patented RGB 256 Colors PSU Fan", "Smart Zero Fan", "Low Ripple Noise", "Fully Modular Flat Cables", and "100% Japanese Capacitors". Now, beyond those items, we also see that the unit is advertised as having a 10 year warranty and that is 80 Plus Gold certified. A quick check of the 80 Plus website does indeed find the unit listed so that part checks out on paper at least. When we move to the rear of the packaging, we find the power table (reproduced below) and the connector count (reproduced below). In addition to this, we find a number of advertising points, an efficiency graph, a fan noise graph, a electrical ripple/noise graph, and an voltage regulation graph. All of which is neat, but I'm not sure ever features of a power supply needs a bar or line graph to make a point. The remainder of the packaging only turns up a few bits about the RGB fan and that is about it so we will just move right on along now.

The power information for the Thermaltake Toughpower Grand RGB 750W indicates that the unit is a single 12v rail unit. This 12v rail has a capacity of 62.5A or ~100% of the unit’s total possible capacity if necessary. The minor rails are each individually capped at 22A with a combined capacity of 120W. Coupled with these outputs, we find four modified 8 pin PCIe connectors, nine SATA connectors, and four Molex connectors. Overall, the Grand RGB 750W is well appointed but it is not, perhaps, the absolutely most versatile 750W unit on the market when it comes to connectors.

Once we open the Toughpower GRAND RGB 750W packaging, we find the power supply, modular cables, mounting screws, the power cord, zip-ties, the user manual, and a product warranty policy. As has been the case with other product warranty policies that we have seen with Thermaltake units, it starts off with the length of warranty as the first section but fails to tell you how long the warranty is on the unit. Instead, it tells you to visit www.thermaltake.com. The good news is we already know that this unit has a 10 year warranty so we can skip that step of going to the Thermaltake website for now. Moving on to the user manual instead, we see that the user manual is a single piece of paper folded like an accordion and then in half as we have seen a number of times now from Thermaltake. On this piece of paper we find connector counts and power labels for the 650W, 750W, and 850W models along with some installation steps, a few troubleshooting steps, and a few basic electrical specifications. All in all, the user manual is again rather light on important information. As none of this is terribly earth shattering, let's move on now and look at the actual power supply itself.
