a power supply question

Hi All,

I am sorry if this question has been asked before.

I have purchased some steppers from Ebay, they are the
powermax II , max 65 volt, 1.75 amp.
(http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=12577
&item=3106027187) I also plan to use the xylotex driver board (3
axis).

My question is, what voltage and how many amp will require to
drive these motors.

The xylotex max voltage is 35 volts so I think I will need a supply
that will give me 30 volts @ 6 amps. Am I correct ? If not can
someone give the correct values. And does any one have a
source for surplus supplies?

Thanks for your help,

Les
