AleixZ: the answer is no, bequiet use specific incompatible cables on purpose :/ I have a corsair HX1200i and I ordered some from aliexpress, but I wouldn't plug them in without having done some tests and measurements outside the computer first (I'm an electrician). I'll keep your question to one side and will say more when it comes (it's 1 month of delivery and my rtx doesn't seem to arrive at all:/ so no info soon)
