Thermaltake Toughpower GF A3 750W PSU Review

The Thermaltake Toughpower GF A3 750W is an ATX v3.0 and PCIe 5.o compatible unit, featuring a 12VHPWR connector that is set at 300W, which is enough for mid-range graphics cards. Its footprint is small, thanks to the 140mm depth, and along with the fully modular design, will be of great assistance during installation. 

The Thermaltake Toughpower GF A3 750W is included in my best ATX v3.0 & PCIe 5.0 PSU picks article.

You can find the reviews of the GF A3 units that I have evaluated so far below:

This is the fourth in a row Thermaltake PSU review, and this time, it is the GF A3 750W, the lowest capacity model of the line, featuring Cybenetics Platinum efficiency and Cybenetics A- (25-30 dB[A]) overall noise output. Contrary to the 1200W model, all other models of this line use inferior fans, and so does the 750W unit, but still, the provided warranty remains the same at 10 years. This is a bold move by Thermaltake. Moreover, the manufacturer for all GF A3 models is HKC, a not-so-popular OEM with good products and designs. I strongly suggest TT change all fans with Hong Hua ones, in the 750W-1050W models, to remain on the safe side, even if this change will slightly increase the prices of these PSUs. The other interesting features of this PSU include a semi-passive operation, which can be deactivated, compact dimensions with 140mm depth, and ATX v3.0 and PCIe CEM 5.0 compatibility thanks to the 12VHPWR connector, which is set at 300W output.
