GIGABYTE TECHNOLOGY Co. Ltd just recently announced their 3 latest compact design power supplies; the P750GM, P550B, and P450B.
GIGABYTE has improved the old circuit design and adopted new high-quality materials. The reduced-size power supplies are more suitable for installation in the increasingly popular small chassis, so that even small chassis can enjoy the high performance brought by the large wattage.

The GIGABYTE P750GM 750W 80 PLUS Gold certified power supply has a full modular design. Its main capacitor is made in Japan along with its 80 PLUS Gold certification, provides a maximum conversion efficiency of more than 90%. This allows gamers to enjoy the graphics intensive games without worrying about the power shortage by providing a high quality and stable power supply while saving a lot of money. In addition, the P750GM introduces the fan stop function, which will stop the fan from spinning during standby mode or when the power consumption is less than 20%, thus increasing the life of the device.

The P550B and P450B power supplies are made from high quality materials and has an 80 PLUS Bronze certification. They provide 550 watts and 450 watts of power supply respectively and provides maximum conversion efficiency of more than 85%. This makes them last longer but also saves users a lot of money.
