Many PSUs have multiple SATA connections on one cable to reduce the amount of cables required Other devices have since adopted the standard as well, such as RGB hubs and fan controllers. SATA Power: This connector is used to provide power to SATA storage devices.Be sure to double-check that your power supply has the connections you need for your GPU before purchasing PSUs will often provide multiple connections on a single cable to avoid having to run additional wires, and for the vast majority of users, this will function the same as running multiple cables. Most PSUs address this required flexibility by providing cables that can be used in a variety of combinations, some of which include 6, 8, 6+6, 8+6, and 8+8, and even 8+8+8 pin connectors. 6/8 pin (PCIe*/GPU): Some GPUs draw enough power from the PCIe* slot, while others require a specific power cable configuration to operate properly.Though it can vary depending on the manufacturer, the CPU cable usually plugs into the top left side of the motherboard, near the I/O on a standard layout Modern CPUs draw more power than the 24-pin motherboard configuration can provide, which is why the additional 4/8 pin cable came into use. 4/8-pin CPU: This connector provides power to your CPU.24-pin Motherboard: The way power is allocated varies from motherboard to motherboard, but the 24-pin connector/cable is frequently used to power important features such as the chipset and PCIe*.The exact cables you’ll use will vary depending on the specifics of your build, but you’ll most likely be dealing with the following:

Though the PSU you purchase should come with all of the cables you need, it’s worth knowing what the individual connections look like. Let’s kick things off by going over the different cables power supplies use to provide power to your system.
