The GSP500PS24-EF is an AC/DC enclosed Power Supply for use with integral system cooling. The GSP500 has been designed to offer a full 500W of output power in a very small mechanical footprint, whilst still providing peak power to 650W, a 5V standby output with 2A of current capability and an input standby power draw of <0.5W when the inhibit is activated. This fan is intelligently controlled to provide the most optimised acoustic noise in the system and further more the GSP500 can provide up to 180W without forced cooling, thus allowing fans to be switched off during periods of lower system loading.
