From the german part of the forum:

Aquaduct 360 => 700W
Aquaduct 240 => 500W
-I'd say these are capacities which are still acceptable as "silent"
For the tubing you can use any connectors you like,
as long as they fit in/to the tubes.
The easiest way to make sure you get the correct parts ist to tell aquacomputer together with your order of the 360XT, what connectors/plugs you need
(Form at the end of the order or
previously contact the support), so they can add it to your order.
