Thermaltake Toughpower Grand Platinum 700W Power Supply Review

Testing results (Regulation & Ripple)

The electrical performance of the Toughpower Grand Platinum 700W is good, with Thermaltake focused on delivering excellent voltage regulation over anything else. True enough, the voltage regulation is excellent, being about 1% for the 3.3V and 5V lines, while the 12V line is just but a bit behind, at 1.35%. Sadly, the ripple suppression is not nearly as good, with us recording a 60-62mV voltage ripple on the 12V line while the unit is under maximum load. This still is a good figure and merely half of the limit imposed by the ATX power supply design standard, but hardcore enthusiasts would expect more from a power supply of this price range.
