Features:Product function: Change the chassis computer fan to DC5521 power supply, please select this line.The new design features a bold DC5521 metal seat, a fan connector, and a solid needle seat welding wire forinjection moldingReminder: This product only connects to positive and negative power supply, and the voltage output depends on the adapter voltage used.Users who choose router heat dissipation racks, if they already have a 12V, 9V, or 5V power supply, can use this dedicated adapter cable to power the heat dissipation rack and solve networkequipment heat dissipation problems.It is common to adapt to 12V or 9V 5V1A power supplies, and devices such as surveillancecameras, routers, andADSL cats are mostly usedSpecifications:Item:DC5521 Power Adapter to 12V Computer Chassis 4pin Fan CableProduct length: approx 20cm/7.87inWire model: 24AWGWire color: blackProduct weight: 18GProduct interfaces: One end is a DC5521 connector, and the other end is a computer fan 4Pin connectorNote:Special note: When using an external power adapter for the chassis fan, the lower theselected voltage, the slower the speed. Fans exceeding voltage will burn out, and a common voltage for fans is 12VThe power of the power supply represents themaximum sustainable power value provided, and the total power of the fan should generally not exceed themaximum power of the power supplyPackage includes:1PC DC5521 To 4Pin Power Adapter Cable
