Yes, but you already have the 5 volt in the PC, the same place you must
connect to to get step and direction signals.

If you buy a high end breakout board, it will have the 5v ps on it.

But, you may need a 3rd power supply if you want to power relays and
such.

But, when you go from 60 watts (Xylotex) to 560 watts, (Gecko) you
gotta expect some differences.

I think the bigger difference is that the Gecko requires a seperate
breakout board and the HobbyCNC and Xylotex boards come with. That can
save between $25 and $150 over the cost of the Geckos.
