DenverCNC box power supply?

Tim,

Is the power supply in the DenverCNC Driver box linear or switcher?
What is its amp rating?

Thank youin advance,

Ballendo

P.S. I'm unclear whether motor cables are included, or not? The
listing for the box says they are; but the fact they are offered for
40 bux on the product page then doesn't make sense?!? Help me
understand please.
