A: no it doesn't

**Q: does this come with a power supply?**
A: The Power Supply for this model is the CP-PWR-CUBE-4 and these are sold separately. Typically this model is deployed in an office setting where a PoE switch would be used to power them, so Cisco does not bundle them with the power supplies.
