I would look for something in the 300-800W range. 3000W is like trying to water your house plant with a fire hose, it might work but it is far from ideal.
I wish I could get the dewalt in Europe but that’s only because of the low price.
That said a Kress will probably last longer as it was designed for running long periods on a CNC machine and its well worth the money.
A Kress 530 FM would be plenty powerful enough for a MPCNC.
