Hi Cakes,
Welcome to our forum. ;D
I didn't see any spec's about whether the power supplies have their voltage regulated and are free of hum. They have a pretty big difference in their output current:
The 1st one can provide up to 7A of current.
The 2nd one can provide up to 1.5A.
The 3rd can provide up to 1A.

How much current does your application need? ???

the powersupply is needed for this charger http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXUF44&P=7, the 1st powersupply in my 1st post is the original one intended for the charger, i lost the powersupply and was looking for a cheaper alternative. thanks for the  help  ;D
