RAMPS and xbox power supply

i have an old 203watt xbox power supply because that seems to be what many people were using to power ramps electronics, and have read a bunch of people's tutorials or wiring diagrams but would like to check with you guys.

has a wiring guide but seems to miss out which screw terminals go where,- or maybe he says to put them only in the 11amp terminals from this photo-

there is no heated printbed to power, will this power the 5 motors and not damage anything?
it has 12 volts,will the board just draw the necessary current for what it needs?
thanks

The way you have it wired in your photo is fine although the two terminals further from the corner aren't necessary since you don't have a heated bed. The terminals closest to the corner is fused at 5 amps and normally will draw about that, or about 60 watts so you should be fine. If you decide to get a heated bed in the future, depending on your bed's resistance (suppose to be 1.0-1.2 omhs) you'll be right at the maximum of your power supply.

If you want to use the RAMPS board to control your power supply via the M80/M81 commands, you'll need to jump through some hoops with a relay to switch the red and blue wires together to turn on the power supply to full power.

ok thankyou
