GS-300 80+

GameMax Micro SFX Design are known mostly as a replacement power supply, but it has now evolved and can be used for Mini-ATX cases, custom built computers, mini-servers, and much more.

Able to detect the differences of wattage that is needed to power up your system, you can be rest assured as it will provide and maintain the most suitable power needed. Thermal fan speed control it will detect the amount of heat generated by the computer. Using this controller to detect the heat levels, it will automatically adjust the fan speed accordingly and the need to worry about the heat levels of a PSU, becomes almost non-existent.
