Thermaltake Toughpower Grand Platinum 700W Review Conclusion

Thermaltake had always been a company with a strong focus on aesthetics, trying to create products standing out of the crowd. The Toughpower Grand Platinum 700W is certainly such a product, being one of the few white power supplies available and possibly the only one on the planet at this point of time which makes use of white cables. The only visual quirk is the use of color-coded wires behind the while sleeving of the native cables, which is an obvious dissimilarity over the all-white modular cables. How about quality or performance though?

Regarding quality, the 7 year warranty alone certainly is reassuring. We believe that High Power did the best possible job they could as an OEM, with a very clean assembly and great soldering quality. The choice of components also indicates that Thermaltake had been trying to create a very reliable product, as even the least important passive component is coming from a well-known manufacturer. 

Although the electrical performance of the Toughpower Grand Platinum 700W unit was very good, we cannot hide it but to admit that we expected something more from a power supply of that league. The power supply displayed great efficiency and very good voltage regulation, being capable of regulating the voltage lines within 1.35% between minimum and maximum load; however, with voltage ripples in excess of 60mV under maximum load, the voltage ripple suppression capabilities of this unit are mediocre, even weak for a 700W power supply with a price tag of $189.99.

The Toughpower Grand Platinum 700W is certainly a unique product in terms of appearance, very reliable and covered by a very long warranty. However, we feel that Thermaltake might have been a little bit too focused on aesthetics and marketing this time around, as the overall performance of this power supply is a few notches behind the competition within its price range. Unless the actual retail price is significantly lower than the $189.99 MSRP price, it would have to compete directly against products such as the Corsair AX760 and the Seasonic Platinum 760, both of which may not share the unique appearance of the Toughpower Grand Platinum but they cost even less while their platforms have the potential of even better performance.


Legit Bottom Line: The Toughpower Grand Platinum 700W is certainly a very attractive and very well made power supply, which ought to please even the most hardcore of modders. Loaded with features and covered by a very long warranty, it will not disappoint the vast majority of users. The high price however pits it against some very stiff competition and enthusiasts who want the best possible performance out of their power supply might be looking elsewhere unless the retail price is significantly more competitive.
