Thermaltake Toughpower Grand 1200W Power Supply Review

Price: $279.00


Thermaltake, established in 1999 and still a relatively new company, offer a comprehensive line of products for the computer enthusiast. We all know that heat can be a killer and the Thermaltake Key 3 Spirit initiative seeks to address the problem and take the case, power supply and cooling as a system and  integrate them all together to keep temperatures under control. Judging by their popularity on the forums and some excellent reviews there's no doubt that Thermaltake produce some excellent cases, cooling fans and processor coolers, but what about their power supplies?

Thermaltake offer an extensive range of power supplies that includes the Toughpower, TR2, Litepower and Evo_Blue series along with a range of universal laptop power supplies. Thermaltakes flagship power supply range is probably the Toughpower Grand series with 650, 750, 850, 1050 and 1200 watt variants. The Toughpower Grand series utilize advanced circuitry, high efficiency, clean and reliable power delivery and a modular design making them, according to Thermaltake, the toughest power supply on the block. Let's have a look at the Toughpower Grand 1200W and see if it lives up to the hype.

Closer Look:

Thermaltake always package their units very well and the Toughpower Grand 1200W follows in that tradition. The top of the box shows a photograph of the power supply along with model number and a little information on some of its major features that includes a generous 7 year warranty, 80 Plus Gold standard efficiency along with Nvidia SLI Ready and ATI Crossfire X certification.











It doesn't finish there because the top face of the box lifts like the cover of a book to reveal more information about the power supply and its major features.



The bottom of the box provides information on the types and quantities of connectors, a comprehensive specification table, more features and conformance/safety marks.


The front and rear faces of the box show the same Thermaltake "Cool All Your Life" logos.


The side panels list some of the major features in several different languages.



Not satisfied with one box Thermaltake put the power supply in a box in a box. This box is a little plainer with just the Thermaltake logo shown on the lid.


Lift the lid and the user manual sits on top of the black foam enclosed power supply with the modular cable bag tucked neatly down the side. Remove the foam lid and the power supply is contained in a black felt draw-string bag.



Bagged power supply along with the full box contents. The Thermaltake Toughpower Grand 1200W power supply comes with a comprehensive set of accessories that includes four black plastic cable clamps, cable straps, anti-vibration mounts and power supply mounting screws. The modular cable bag isn't big enough to hold all the cables so there's a further plastic bag full of cables.



The Thermaltake packaging is once again excellent with a great set of power supply accessories. Let's move on and have closer look and see how well it performs.
