Thermaltake Toughpower Grand 750 W Power Supply Review

Conclusions

The new Thermaltake Toughpower Grand 750 W is a good power supply. During our tests it achieved very high efficiency, peaking above 90%, extremely low noise and ripple levels, and an adequate number of connectors for a 750 W product. Due to its highly overspec’ed components, we could easily pull 880 W from it.

However, compared to other 80 Plus Gold power supplies, it is not the best game in town. On the technical side, the +3.3 V and +5 V outputs, though inside the allowed range, dropped too much when we pulled 600 W and above, touching the lower limit. Competing products have a better voltage regulation.

But what will probably kill Toughpower Grand 750 W is its price, which comes with a suggested price of USD 200 in the US. It can be found on the market on the USD 180-200 range, and at this range you can buy 850 W 80 Plus Gold power supplies, like the OCZ Z Series 850 W (USD 175), NZXT HALE90-850-M (USD 180), and Corsair AX850W (USD 190). So, unless Thermaltake drops the price of the Toughpower Grand 750 W below USD 160, we think that you will be doing a better selection by picking any of these other three competing products.
