Thermaltake GF2 ARGB (750w) TT Premium Edition PSU Review

Efficiency

As this is an 80-plus Gold efficiency rated power supply, Thermaltake has clearly set a rather high bar in terms of how much power goes in versus how much comes out to your components. – While the GF2 ARGB doesn’t provide any results significantly beyond above and beyond the required remit, the efficiency scores provided in our test were excellent for the ‘Gold’ standard.

As you can see in the chart below, other than at 100% load, the Thermaltake GF2 ARGB provided consistent efficiency scores of over 91% meaning that, by and large, for an 80-Plus Gold rating, this is definitely towards the higher end of the tier.

PFC (Power Factor Correction)

When this power supply is put to work, the PFC quickly ramps up to an impressively high level, scoring 0.984 at 100% load. Which, just in case you didn’t know, is a very high rating indeed. In fairness, though, we can’t honestly say that we were overly surprised by this. For the masses of Thermaltake power supplies we have reviewed in the past, they have consistently provided excellent PFC results in our testing and the GF2 ARGB, quite simply, is yet another great example of this!

Voltage Regulation

With the exception of the -12V rail (which isn’t overly important in modern PC designs anyway), the results provided in our voltage regulation testing were solid and consistent. A quick look at the overall average deviancy highlights that, regardless of the power output, the GF2 ARGB provides a power delivery that is nearly always (give or take a minimal margin) of the same level.

Are the -12V results bad though? Well, in a nutshell, no. – Based on many other results seen in the past from various manufacturers, this is, quite honestly, about what we expect to see. And again, we should highlight, the importance of this rail has significantly dropped over the last 10-20 years of PC design.
