The Thermaltake Toughpower GF3 1200W presents excessive efficiency and compatibility with ATX v3.0 and PCIe 5.0. The truth that it’s noisy at excessive masses did not stop it from incomes a spot in our finest PSUs listing. Its essential competitor is the Cooler Grasp MWE Gold 1250 V2, which isn’t ATX v3.0 prepared and lacks a 12VHPWR connector.
Thermaltake lately launched its GF3 line, ranging from 750W and going all the best way as much as 1,650W. The decrease capability fashions, as much as 1,200W, are made by Channel Nicely Expertise, whereas the 1,350W and 1,650W items are by Excessive Energy. This overview will take a look at the strongest CWT-made GF3 unit, which comes with a 600W 12VHPWR connector, supporting Nvidia’s flagship, the RTX 4090. There is no such thing as a want for an ATX v3.0 or PCIe 5.0 prepared for the graphics talked about above card. You simply want a powerful PSU, ideally 1,000W or extra highly effective.However, if you wish to keep away from adapters and be future-proof, a PSU just like the GF3 1200 is the best way to go.

The Toughpower GF3 1200W has a local 12VHPWR connector, and it’s ATX v3.0 suitable, that means that it may well ship double its energy, 2,400W, for 0.1ms durations with out shutting down or having every other working points. That is to deal with any energy spikes from the GPU or every other system part. Thermaltake additionally outfitted it with a fluid dynamic bearing fan and different top-quality elements, which ought to enable it to survive the prolonged, ten-year guarantee.

The cables are lengthy, and the gap between the peripheral connectors is ample. It might be good to have three EPS cables and connectors, however the modular PCB would not have area for further sockets. The quantity of legacy PCIe connectors is low, however from the second you could have a 12VHPWR (600W) connector, you can be fantastic. Lastly, there are not any in-cable caps, and all cables use thick, 16AWG gauges for decrease voltage drops at excessive masses.
