SilverStone SFX Bronze ST45SF 3.0 450W

This state-of-the-art SilverStone ST45SF 3.0 power supply is stored in a compact SFX chassis, but thanks to the reduction in its size you can use it in an ATX case. It is fitted with innovative components and is capable of operating for an extended period of time (24/7) at an ambient temperature of up to 40°C. Demanding users will appreciate its great efficiency which is in the range of 82-85%. The ST45SF v3.0 offers a maximum current output of 37.5A on the 12V rail, making it also suitable for medium-sized graphics cards. PCI Express connectors are also part of the power supply's package and its cooling is provided by a 92mm fan with a thermal control running at a low noise level of only 18dBA when idle.
