This 12in 3-pin (TX3) to LP4 Power Y-cable lets you connect your 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. This high quality adaptor is backed by StarTech.com's Lifetime Warranty.
