A good clean power supply unit (PSU) is the most important part of a modular system. A proper [[Power supply (linear)|linear power supply]] and good distribution makes a big difference to the stability and sound quality of the system.<ref>[https://www.muffwiggler.com/forum/viewtopic.php?p=1470018 Best Eurorack Power Supply (PSU) for your buck?], Muff Wiggler forum, 23 Feb 2014</ref> [[Power supply (switching)|Switch-mode power supplies]] are smaller, lighter, and much more efficient than linear power supplies but produce more noise, (above audio range) on their output.<ref>
