My little dude has run out of room on his Wii U and needs an additional self powered hard drive. I have a WD Blue 320 gig drive
https://www.newegg.com/Product/Product.aspx?Item=N82E16822136197 and an enclosure
http://www.microcenter.com/product/323860/25_sata_to_usb_20_external_portable_hard_drive_enclosure with a jack for additional power but I'm having a hard time figuring out the voltage and connector size for the additional power jack and wall wart. Any help would be appreciated.
