Thermaltake Toughpower GX1 Gold 700w Power Supply Review

Efficiency, PFC and Voltage Regulation

Voltage Regulation

In terms of voltage regulation, the results are highly impressive. Across all the separate voltages, the Thermaltake Toughpower GX1 gave remarkably consistent figures. As can also be seen below, the deviance between these (to the ideal) is all less than 1%. Even the -12V rail, which is traditionally a bit of a hit and miss performer for power supplies gives solid results.

Put simply, everything looks really good here!

Power Efficiency

The Thermaltake Toughpower GX1 is a gold rated power supply. As such, it has rather strict requirements as to what it needs to achieve to get this rating. When testing this at various load levels, this power supply gives excellent efficiency figures. The results in our chart below are almost identical to those that Thermaltake advertise on the packaging. Once again, a credit to Thermaltake.

The only difference we noted is that our starting efficiency percentage is a little lower than their on the packaging, but contrastingly, our 100% load efficiency is a little higher. While these figures are comfortably within the ‘gold’ standard, it does on occasion wander into the Platinum territory. Certainly not a bad thing for any power supply when it performs better than it has to.

Power Factor Correction

The PFC ratings for the Thermaltake Toughpower GX1 are initially a little lower than we usually expect to see. Despite that though, once you put it to work the figures get more and more impressive. This would indicate that this power supply is at its best when working rather than when idling. In addition, it also seems that the more you ask, the better it gets!
