Comparison of Eurorack DIY PSUs
Power supplies
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
Unless you're qualified to work with mains electricity ready made external transformers are safer. Also remember charged capacitors can deliver quite a jolt.
