THE CRUNCH
Gamemax’s RGB PRO 750G is a 750W fully modular power supply that leans heavily on its lighting to justify its $105 price tag. It features a 140 mm ARGB fan, ATX 3.1 and PCIe 5.1 compliance, and a native 12V-2x6 connector for modern graphics cards. The unit is built with Japanese 105°C main capacitors and includes an ARGB sync cable, though the bundled accessories are otherwise thin. The review notes that the 80 PLUS Gold efficiency rating is not found in public certification databases, meaning the badge is a manufacturer assertion rather than an independent verification. Gamemax rates the unit at 40°C ambient, with output derating by 20 percent above that temperature, effectively limiting it to 600W in a hot environment. The RGB lighting is a highlight, using a ring of addressable LEDs to create a glowing hexagonal halo rather than illuminating the fan blades directly. The unit is slightly longer than the ATX design guide recommendation, which could make cable management tighter in some mid-tower cases.
Gamemax positions the RGB PRO series as 'affordable luxury', but the 750G sits in the middle of its catalog and costs more than several other 750W Gold units currently sell for. The company claims 25 addressable lighting modes and a 40°C operating range, though the lack of verified efficiency certification means buyers must rely on the manufacturer’s word for performance claims. At 165 mm deep, the unit is 25 mm longer than the ATX standard recommendation, which may restrict fit in cases with limited cable clearance behind the power supply shroud.
The power supply’s protection is described as adequate rather than generous, and the bundle contains only the essentials: an AC cord, mounting screws, zip ties, a manual, and the ARGB sync cable. While the sleeved cables are stiffer than flat alternatives, they are appropriate for the wattage and feature a decent paint job that is unfortunately prone to fingerprints. The lighting effect is praised as better executed than the price suggests, offering a diffused, even glow without visible hot spots.
Gamemax is an OEM brand founded in 2013 that sells cases, coolers, monitors, peripherals, and power supplies. Its power supply catalog has historically been uneven, with some models existing purely to hit a price point and others, like the recent Lion Core series, carrying genuine certification. The RGB PRO 750G attempts to bridge this gap by offering a visually striking design and modern connectivity features, though the unverified efficiency rating and premium pricing may give some buyers pause.
