Best Answer - Chosen by Asker:

that is a dell optiplex computer!. its got a 6-prong power input on the back of it!. make sure that the AC power adapter you have pictured has 6 holes in the part that you stick in the computer!.

That is, to say the least a bit different than I have ever seen, just check the specs that come with your pc!. (or look on the back to see amperage and voltage info!.) Match it up with the specs on the site!. =]Www@QuestionHome@Com
