Hello!

Thank you for the instructions, and thank you to all the people that posted helpful comments! I followed the instructions well, but I skipped over the “It’s easy to use a separate power supply for only the heated bed” part of the instructions! I was following it step by step thinking that it would be able to power the stepper motor drivers, extruder, extruder fan, and possibly another fan on my RAMPS 1.4 board.

I looked over the voltages and realized the yellow wires are +12V and the black wires are ground. Then I went looked up the power voltages and amps required and noticed the Ramps need +12V and greater than 5A to function. This fits the requirements of the stepper drivers, extruder heater, and fan.

Would it be safe to connect the +12V wire into the 5A + area and the ground wire in the 5A – area or will it give off to much amps. I’ve searched online for a while and it mostly says 5A or greater, but I really want to triple check this so I don’t damage any electronics. My AC Adapter brick says the 12V gives off 16.5A.

My Xbox 360 power supply had 203 Watts, but only 3 yellow, and 3 black. Would that affect anything as well? I don’t think it would…

Now I also have a bit of firmware questions! I noticed on a version of Marlin I downloaded had an Xbox-360 PSU option, and different types of Marlin, and in Repetier Firmware do not have any other option than ATX PSU. Would this matter if the firmware has a special selection for this type of PSU or should it be selected as ATX if there is no Xbox PSU option?

Thank you to anyone for reading! I hope to see an answer soon!

*A thing I figured out: If your butt Splices are Heat-Shrink, make sure all the rubber cord protector is out of the way of butt splices or they catch on fire and melt. Along with that you could burn/melt through the cords that are black, yellow, or red and blue.
