Do I need to purchase additional cables for my hard drive or no?

[Sians]

Sorry if this is a dumb question, its been forever since I last built a PC and I'm not really sure about this. So I just bought a hard drive that comes with no cables. I know my motherboard came with four SATA 3 cables, but what about the power cable for the hard drive? Would that be on the PSU, or do I need to purchase the cable?

for reference these are the motherboard and psu

Sata Cables should come with your motherboard. The power cable is sata power and is connected to your power supply.
