Did the external drive work with the original power supply? | Report abuse aslak November 3, 2012 1:51:52 PM Thanks for reply, but do you now for sure if i can use this power supply | Report abuse GhislainG November 3, 2012 3:57:27 PM Presuming the polarity is the same, the specs are similar (12V at 2.0A). Most replacement Personel Storage 3100 OEM PSU replacement are 3.0A, but a few sites also sell a 2.0A unit; therefore I'll presume that 2.0A is enough. Did it work fine with the original PSU? | Report abuse fzabkar November 3, 2012 7:56:25 PM The polarity is indeed the same (centre pin positive): http://s3.amazonaws.com/kpsurplus_images/1aa78002f8a8e3...

Did that external drive work before or is it a unit that you got for free and hope to get working? | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Storage>Powersupplye> Related ressources: ForumNeed up to date SSD advice.
