The brand bequiet! belongs to the German distributor Listan. This company has released several power supplies with the 80 Plus Gold certification, under the Straight Power E9 series. Five of them (400 W, 450 W, 500 W, 600 W, and 700 W) don't have a modular cabling system, while three of them do (480 W, 580 W, and 680 W). These models carry the letters "CM" for "Cable Management." Let's see if the 680 W model is a good option.
