Thermaltake Toughpower 750 W (W0116RU) Power Supply

Conclusions

Even though we found several unusual things inside this power supply, it uses high-end power rectifiers on its secondary stage, not only from a very good supplier (ST Microelectronics) but also carrying a maximum current and power rated far above the labeled power for this power supply.

Of course the maximum power a power supply can really deliver depends on other components as well, like the transformer, the coils, the electrolytic capacitors and even on the gauge of the wires used.

Unfortunately we don’t have the necessary equipment to make a true power supply review – we would need to create a real 750 W load to check if this power supply could deliver its labeled power or not.

Even tough the rectifiers are top notch, the maximum labeled power was measured at 25º C instead of 50º C like other good high-end power supplies. Why this is important? The higher the internal power supply temperature, the lower power it can deliver. You will never get 25º C inside a power supply; typical real-world values are found between 35º C and 40º C. So a power supply labeled at 25º C may not deliver its labeled power when running in the real world.

We also missed on this power supply label the individual power each output can deliver.

It was also interesting to see that this power supply isn’t manufactured by Thermaltake. It is actually a relabeled CWT PSH750V-C01 unit. Several power supply “manufacturers” are doing the same, simply relabeling models manufactured by others. Some manufacturers may be using other companies only to manufacture products that were really designed by them, which isn’t the case with Thermaltake.
 
This power supply provides features also present on other high-end power supplies, like high efficiency (meaning a reduction on your electricity bill), active PFC, modular cabling system and some protections. We say “some” because power supplies from other companies provide more protection levels, like undervoltage.

Its price seems to be right for its labeled power and features.
