Comparison of Eurorack DIY PSUs
A good clean power supply unit (PSU) is the most important part of a modular system. A proper linear power supply and good distribution makes a big difference to the stability and sound quality of the system.[1] Switch-mode power supplies are smaller, lighter, and much more efficient than linear power supplies but produce more noise on their output.[2]
Safety
Mains voltages can kill and capacitors in disconnected power supplies can still deliver quite a jolt. Unless you're qualified to work with mains electricity, ready made external transformers are safer.
