Gigabyte just made a bunch of high-wattage, compact power supplies

Gigabyte has announced three new compact power supplies, available in 450W, 550W, and 750W variants. The P750GM is a fully modular 80 PLUS Gold certified unit, while the P550B and P450B are 80 PLUS Bronze certified and are only semi-modular. 

The company says it has improved on the old circuit design and adopted new higher quality materials, which allowed it to reduce the length of the P750GM to just 14cm. It hasn't sacrificed on performance and stability though, and it claims that both aspects can still be improved even in this smaller footprint. The more compact size makes the power supply more suitable for use in smaller chassis, which in turn will allow system builders to install more powerful hardware as well.

The main capacitor of the P750GM is manufactured in Japan, and the power supply boasts a maximum conversion efficiency of over 90 per cent. In addition, it supports motherboards that have an 8+8 or 8+4 CPU power supply, so you'll be able to fully utilise higher end boards as well. It also offers a fan stop function, where the fan stops spinning during standby mode or when power consumption is less than 20 per cent, in this way increasing fan longevity and reducing noise.

The 80 PLUS Bronze certified P450B and P550B have a maximum conversion efficiency of over 85 per cent, and they use a 12cm hydraulic bearing fan that is supposedly quieter than regular sleeve bearing fans.

All three power supplies come with the usual OVP, OPP, SCP, UVP, OCP, and OTP current and voltage protections.
