What makes the Sparkle R-SPI700GHN unique in our eyes is that it is not oversized. This power supply is 700 watts, yet you will find it no more bulkly than a standard atx power supply. As a matter of fact this power supply is only a standard 5.5 inches deep. An 80 PLUS efficiency rating along with plenty of connectors makes the SPI700GHN compatible with just about everything out there. Four 12 volt rails can delivery a combined current of 72 amps while keeping nice and cool with the quiet 120mm ball bearing cooling fan.
