First-time build, PSU cable issues

I am currently wiring up my build. I am using a Corsair CMPSU-850HX as my power supply.

Since it is a modular PSU, it comes with a bag of cables that connect at one end to the power supply and at the other end to a device. However, it's not just one end.

Each cable has 4 of whatever connector.

So, if I put it a SATA power cable into the PSU, on the other end there are 4 SATA power connectors, strung throughout the cable.

My question is, can I power four SATA devices with that one cable? Or do I have to get another SATA power cable in order to power more than one SATA device?

Thanks in advance.
