This is one hell of an output and for those with a packed out case this is a must, Note the high amperage of the +3.3v rail, this will make sure that your motherboard and CPU will get the power they need and very stable at that. The unit has two 80mm fans, one of which has a seperate cable to plug onto one of your motherboard fan connectors to enable fan speed monitoring which is very useful. Another good feature is that there are no less than seven power connectors.
