Final Thoughts

At this moment, only those computer enthusiasts and gamers with highly overclocked CPU's and either GeForce 8800 GTX/Ultra video cards in SLi, or Radeon HD 2900 XT video cards in CrossFire will begin to tax this power supply unit. Even with the highest demanding CPU and GPU combination available today, the total power consumption is still under 1000 watts. Of course, this is the kind of item which would hopefully future proof a long-term computer investment. At least, that's what we hope.

There were very few design flaws discovered, but the biggest among them is the exposed wire glaring at you from the image below. Certainly the terms "could have" and "should have" apply here, but with rolled edges on the grommet-less chasses opening it seems unlikely that this will become a problem. Unsightly yes, dangerous no.

Thermaltake Toughpower 1200W Modular PSU

What we have discovered in the Toughpower W0133RU is a very high-output power supply unit, with everything you would consider necessary for future-proofing your computer for lets say, ten years. There are no irritating LED lights shining in every direction to keep you up at night. There is only one large 140mm cooling fan, which operates nice and quietly, so you won't be annoyed by power supply fan noise. And there is no lack of cables, with room for expansion into the 8-pin PCI-E interface.


Thermaltake has done an excellent job of taking the retail package and turning it into an active advertisement for the product contained inside. Both front and back of the retail packaging are colorful and informative, which is always the right combination for someone looking at this product on a shelf.

Even after you unpack the Toughpower 1200 from the box, the finish and features are enough to keep you happy. While the short-sleeved cable groups are not a personal favorite, the chassis finish and modular plug interface are very appealing. Thermaltake could have improved the appearance with full-length sleeves and a more refined chassis.

The sleeves have already been noted, just as the missing chasses grommet for the native cable groups, so there are very few issues involving the construction outside of these. The chassis is very well made, and the interface is also high quality. The 140mm cooling fan will undoubtedly outlast your needs, and the silicon mounting gasket will absorb an ample amount of vibration.

1200 watts is a whole lot of power; too much for most people. To nobody's surprise, this power supply performed very well without a single function problem. Both the voltage regulation and power ripple were among the best ever recorded, and the 8-pin PCI-E 2.0 connectors will allow for future integration with hardware.

Available right now at for $399.99, the Thermaltake Toughpower W0133RU 1200W Modular PSU is priced directly at the center of the index.

I was very impressed with the overall performance of the Toughpower W0133RU by Thermaltake, and would surely recommend this 1200W Modular PSU to anyone with unusually high power needs or a unit with room for growth. Attractive price and style along with effective voltage regulation and low power ripple mean that you can't go wrong with the Toughpower W0133RU.
