Product Description

This 12V 1A DC power supply and adapter cable combination allows you to power any standard 3-pin or 4-pin computer fan from a wall outlet. The power supply and adapter cable use the very common 5.5mm x 2.1mm DC barrel plug making them very flexible. Other power supplies and additional cables can be used to fit your requirments. Please note that while almost all computer fans have current requirements well within the 1A capacity of this power supply that's not the rule.
