Hello Christophe

> Can convert my (old PSU1) powersupply to 110V, or should I buy a new PSU and install that?
If you think you can obey the warning: "The following notes are intended 
for experts onyl. Carrying out of works described in these documents is 
allowed only for authorized personnel who are familiar with all valid 
safety rules" and are able to solder and handle a screwdriver, then get 
the description here:

If not: any electronic repair service will do it within 30 minutes of 
work (disassembling and assembling the housing is the main effort).
