Cooler Master GX 750 W Power Supply Review

Conclusions

Cooler Master GX 750 W looks like a good option for users looking for a mainstream 750 W power supply, however it has a major flaw that prevents us from recommending it: noise level at +3.3 V and +5VSB outputs were above the maximum allowed when we pulled 600 W and above from this unit. High noise levels overload and can even damage components on your computer.

If you are looking for a mainstream 750 W power supply our recommendation is still Seventeam ST-750P-AF, which is USD 20 cheaper than Cooler Master GX 750 W and provides better performance (namely higher efficiency and lower noise levels). Of course GX 750 W offers as advantages having four power cables for video cards and more SATA power connectors, but it is only safe to run this new Cooler Master unit up to 450 W.
