I need a laptop PSU, standard 19v 90w or whatever. What's the most efficient option that's reliable? I usually just go Delta but if I can save a couple of watts with another brand then I will consider it. Though it does have to be available pretty cheaply on Ebay or whatever, too.
 
Okay, can anyone at least provide some efficiency figures for the Delta power supplies? e.g. the 90AB? Do they have different efficiencies between, say, the 90AB, CB, FB, SB, etc.? Or is it just the power connector and such that's different? Or the laptop company they're selling to?
