The Gamemax RGB PRO 750G is a fully modular 750W ATX power supply featuring a 140 mm ARGB fan. It is compliant with ATX 3.1 and PCIe 5.1 standards and includes a native 12V-2x6 connector. The unit is rated for 40°C ambient operation, with a 20% output derating applied at temperatures above 40°C.
The device is marketed as 80 PLUS Gold certified, though it currently lacks entries in the CLEAResult, Cybenetics, or PPLP databases. The MSRP is set at $105. Internally, the unit uses a Nichicon 390 μF 420V primary capacitor rated to 105°C, while secondary capacitors are supplied by Teapo.
The chassis measures 165 x 150 x 86 mm. Cooling is provided by a PowerYear 140 mm fan with a claimed fluid dynamic bearing. The unit features 25 addressable lighting modes, which can be controlled via a rear button or synchronized with a motherboard using an included 5V three-pin cable.
Testing shows the unit achieves 80 PLUS Gold efficiency levels, averaging 90.8% at 230 VAC and 88.6% at 115 VAC. The cooling profile is aggressive; the fan runs constantly, remaining quiet below 300W but reaching nearly 50 dB(A) at a sustained 750W load. The manufacturer provides a 10-year warranty.
