Hi Rongee
The power supply in the sapphire is a 24volt 360 watt unit -at least according to the machine spec and my unit.

to see the internal firmware settings you need to use something like Prontiface and connect via the usb connector on the sapphy . Prontiface is available as a free down load i don't remember where I got it from but I will forward them when i have had a chance to look them up.
