The Thermaltake Toughpower XT 1375 W is a powerful PSU with very high capacity and good performance overall, thanks to the advanced platform it is based on. This unit can easily power an ultra high-end system with dual CPUs and up to four VGAs installed along with a ton of peripheral devices, drives, etc. Also, despite the huge power it can deliver, it is equipped with a silent fan, which doesn't spin at low loads. Nevertheless, here lies a problem I had spotted, at least in my opinion. I think that the fan comes into play rather late, meaning that the ambient temperature has to significantly increase and surpass 40°C in order for the fan to engage. This unnecessarily stresses many sensitive components, e.g., electrolytic caps, and shortens their lifetime. However, Thermaltake equips this PSU with a 7-year warranty, so the company is pretty confident about its reliability and, on top of that, you will be covered if anything breaks down. Surely, the biggest drawback of this unit is its very high price, which, in essence, cripples its price/performance ratio. Thermaltake should revise this price immediately, if it wants at least to boost the PSU's competitivity and increase its sales.

To sum up, the TPX-1375M has surely much to offer but, unfortunately, costs way too much, so I can't recommend it, since at much lower prices one can find even higher capacity units with equally good efficiency levels.
