Power supply

Power supply unit

The power supply is a new server power supply, which I disassembled and extended the cables that had become too short. It is important to have a good air circulation to avoid heat accumulation. The power supply is cooled by 3 fans with 55m³/h airflow each. The fans are quite quiet, which makes the operation of the power amplifier as a desktop PA possible.

The power supply was additionally suppressed with two capacitors and the placement of the power supply below the mounting plate for the low-pass filter and control is also positively noticeable.
