Making a switch from AC to DC to run your low voltage christmas lights then a SMPS (Switch Mode Power Supply) is definately in your future.
I have multiple 350w SMPS's in both 27v and 48v ratings. These were all purchased from ebay and have proved reliable. I will admit to buying a spare for each voltage rating, just in case.
Just do a search for "meanwell" and you will find many 350w ones to buy.
They can be found with the following outputs, 12v, 24v, 27v and 48v easily. these cover nearly all the requirements.
All of the ones i have are fan cooled and should be quite happy running at 100% load.
The only limitation with the SMPS's above is they cannot be connected in parallel if you need more current to a single controller. Due to the high cost of new 600w and greater supplies it's often just as cost effective to split the lights onto more controllers.
Cheers
