The larger 30" displays needed a certain power level capable Mac when they were first introduced, but anything newer should be OK.
Have you tested it with anything, PC or anything that has a port that would work?

Hello, yes there reason it doesn't get power is because you are without a power cable.

A kettle lead will do, but it should have had a correct cable in the box. Have you checked back there, or where ever it came from, to see if the power cable is still there?
