This 12-inch 3-pin TX3 to LP4 power Y-cable allows to connect CPU fan directly to the computer power supply, instead of connecting it to the designated motherboard port. The adapter cable features a TX3 connector for connecting to the CPU fan, as well as a female LP4 connection to the computer power supply and an extra LP4 male connector that compensates for the used of the LP4 connector used to connect to the power supply.
