Introduction and Features

The Toughpower 1,200W is targeted towards high-end power users and gamers who want a power supply with plenty of reserve capacity that is stable and efficient. And our testing shows it delivers!

Thermaltake has six new power supplies in their Toughpower Specialty Series with Cable Management, which range in output capacity from 650 to 1,200 watts!  These new models all feature a large 140mm cooling fan, high efficiency, active PFC, quiet operation, and ATX12V 2.2 compliance.  In addition, the power supplies come with sleeved, modular cables and include a silicone rubber mounting pad to help reduce vibration noise.  We will be taking a detailed look at the Thermaltake Toughpower 1,200W PSU (W0133RU) in this review.

In addition to the power supply the box also contains a package of 13 modular cables, a heavy duty power cord, mounting screws, silicone rubber gasket, and a 20-page User’s Manual. 


Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test.  Each power supply is tested under controlled, real-world conditions up to its maximum rated load, using both 115 VAC and 240 VAC line voltage.  Our current suite of tests includes:


  • DC Load Regulation
  • DC Line Regulation
  • DC Cross-load (unbalanced load)
  • AC Ripple and Noise
  • Power Factor
  • Efficiency
  • Differential Temperature
  • Noise
  • Size and Weight
