Closer Look:

While there may not be a ton of design options when it comes to the external appearance of a power supply, Thermaltake has taken a few liberties in the overall finish that sets this unit apart from other units.  It has a matte finish on the exterior and this of course helps keep fingerprints and dust from being too obvious if you have a window in your case.  One thing that you'll notice too, is that the corners of the unit are rounded and this gives it a very distinct look that is very appealing.  The rear of the unit has a nice open grill as well as a lighted power switch and even a nice decal that lights up with the company name.  This is a nice touch that shows Thermaltake is proud of this unit and wants people to know who makes it.  I love that pride.

Thermaltake uses a pretty typical modular system on this unit and have separate connector styles for PCIe and Molex/SATA connectors.  While I do prefer the modular system on the NZXT HALE90 and Sentey units, Thermaltake still has a nice layout and the non-modular cables come through the case in a nice, clean protected area.  The overall build quality and curb appeal are great.

PSU Label  

Although the Thermaltake Toughpower Grand 1200W PSU claims that it can handle 1200W of power, with the ratings on the rails, it should be able to handle more - and easily 1200W continuous load.  If you do the math on this PSU you'll see that the 3.3v adn 5v lines actually total 207.5W - and up the 180W combined conservative rating set out by Thermaltake.  Also the +12v1 and +12v2 lines are very large and equal 105A which is 1260W - again, a bit up from the 1200W rating.  Once you toss in the +5vsb and -12v lines, we manage a total output rating of 1507.1W.  I think it's safe to say that if you have any other major device plugged into the same wall as this PSU if it's maxed out, you'll blow a breaker in most houses.  Thankfully, the new shop here at BCCHQ South includes 80A of service in my office = almost 10,000W.  I'm good.

On the next page, we'll take a quick look at the cables before we jump into the PSU itself and then run some tests.
