xiwai ATX Molex Micro Fit Pitch 3.0mm 4Pin Male to Open Wire Power Adapter Cable (15cm 20AWG UL1007)

It’s a standard fit and worked well as a replacement cable for a 3D printer Kobra S1 feeder.

I saw that somebody else wrote that it worked to connect some LED lights to a Bambu A1 printer. I just wanted to add, if anybody else will be looking for this info, that it also worked with a P1 printer.

For those of you trying this for use with A1 and AMS Pro 2 you need to swap some wires with is really simple. If you look at the cable and consider the "top" to be where the locking clip is. The bottom yellow and black need to be switched on one end. I cut yellow and black in the middle rather than trying to swap pins and reconnected the cut wires. Is working perfect on my A1 with AMS Pro 2 and I'm using the P1/X1 buffer since I couldn't ever catch the A1 hub in stock. Works perfectly once those two wires are either swapped at the pin point on one side or you can splice them in the middle like I did and connect them to the other.

Works great.

Not for a normal ATX case. Far too small, will not fit a CPU motherboard slot.
