It somewhat saddens me that you didn't read my post. A couple of days ago I posted "Definitive? PSU answers".
Please, read the posts regularly. That way, if there's something you see u wanna leave a comment on, you can - and that timid newbie goes up!
Mind you, the post is only about 5 below this one, I'm surprised you didn't see it!
Basically, you have to have the right polarity and other stuff.... but i'll let you read up on it in my earlier post :P
