Review on Power supply be quiet! System Power 9 600W by Petar Buchkov ᠌

In general, the block works properly, but this squeak spoils the whole impression of the block. I couldn’t change it in CSN, they don’t have any squeak :( My system is ryzen 5 2600 + GTX 1080 Got pros: -Black color (I don't like colorful accessories) - All necessary wires are present Its cons: Rigid wires, but bend as it should be possible) Beeps under load. After 10 minutes of playing the game, the head starts to go round
