Entry-level system power supplies, which, on the one hand, cost a little more than the Chinese no-name counterparts, and on the other hand, are not examples of total savings. The number of available connectors here allows you to easily assemble an entry-level or mid-level work or gaming PC with a wide variety of hardware configurations. The maximum power of 700 - 800 W is enough to power a high-performance Ryzen 7-caliber processor and a GeForce 3070-level graphics card. Well, the presence of all the necessary basic protections (OVP, OPP, SCP, etc.) will save you from unnecessary worries about the safety of system components.


The secret of the low price lies in the fact that the manufacturer saved on official certification: despite decent efficiency, GM power supplies did not pass the full-fledged Energy Star quality control programme and cannot even boast of having a “bronze” quality certificate. According to the manufacturer, for entry-level assemblies, the base class “80 PLUS” will be enough, which puts forward minimum requirements for the quality of the power supply. In particular, a mandatory requirement is an overall efficiency of around 80% at full load on the line, or an efficiency of at least 85% at a load of 50% of the rated power of the PSU.

The range of the GM series is unusually concise. In fact, it combines three models: the original GM semi-modular power supply with an efficiency of around 85% (power from 400 to 800 W), a GM modification with a modular connection, and a snow-white version for modding assemblies. Also on sale you can find modifications of these power supplies with the prefix G in the name (for example: Gamemax GM-600G). These are slightly more expensive and powerful variations of the original models with increased efficiency up to 92% and a slightly more performant main 12V line.
