Tech Inferno Fan>> June-16-2015: Dschijn advises there is pre-fabricated Dell DA-2 to barrel+PCIe cable is available on ebay-US for US$16 or US$21!! Perfect to use a 220W Dell DA-2 (enough for a GTX970) use with the AKiTiO Thunder2 eGPU enclosure or others using a DC barrel connector. That being the most plug'n'play solution to use this AC adapter from the three other highly regarded ones posts in order below.-> no longer being sold
