Please ensure that you purchase a 12 Volt power supply with the correct Amp rating.

NOTE: I have purchased and used this power supply. At the time of adding to the wiki I have used this power supply for approximately 40-50 hours of printing on a Select Mini V2 without any problems. The barrel plug fits the printer snugly as it should. - Winkeyes AC 100-240V to DC 12V 10A Switching Power Supply Adapter
It was reported by a user on July 3, 2018 that this power supply is now shipping with a 5.5 x 2.1mm on all outputs.
This power supply has a 5.5mm x 2.5mm connector and includes a pigtail splitter with eight 2.1mm connectors. The splitter cable is not needed. The product description refers to the 2.1mm pigtail ends.

NOTE: As of the last time I purchased on June 24, 2017 and Amazon reviews from January 2018, the power supply did ship with the appropriate size connector which is 5.5 x 2.5mm. This may not be the case any longer so I'll try to locate a suitable replacement that isn't $48. - 12V 7A 84W Adapter AD/DC 110V 100-240V 50/60 Hz to 12V Power Supply - Delippo 12V 10A 120W Power Adapter Strip Light Supply 5050 2835 LED strip 100V-240V Power Supply
