(BTW, the headline says 4 pin DIN, and that's what the picture shows, but the details say barrel connector - you'd want to clear that up with the seller)

Would be mighty convenient if it did have the right pinout.  You can always ask them what the pinout is, and compare it to the cable you cut (use a meter to see which lines go where on the plug for the mothernoard.

Some folks have uppgraded to a 15A supply (search other posts). Less likely to burn out, but the 120V packaging is more vulnerable in that route. Positions you better if you want to upgrade the heat bed though.

My SD press power supply just died, I ask solidoodle but the dont have and I really need it , I read that a xbox power supply will work. The issue i have is I dont have a clue about the wiring, I attaching pictures of the cuts a I made (xbox and press power supply) , any reccomendation? As far as I know, the yellow wires on the xbox are the 12 V , but it has 4 (3 thick 1 thin) and 1 black is GND (but also has 3 thick 1 thin)  I´ll appreciate any help.
