=== Audible noise ===
In very rare cases a weak high frequency audible noise can be heard from computer system - <br>
“Coil whine” and piezo noise from ceramic capacitors is a documented phenomenon that cannot be 100% eliminated. It is unlikely to be as loud as the fans found in most computers, and is usually less audible than the noise emitted by hard disks.<br>
An interesting phenomenon is that this electronic noise is often reduced under load (due to less power switching/trimming). Some users apply less aggressive power management and report reduction in noise.
=== Pigtail unterminated DC cable ===
Pigtail DC cable - unterminated on one end and on the other uses standard 5.5mm x 2.5mm barrel plug with mechanical twist-lock.<br>
