I am very satisfied with this average power supply of 650W, the efficiency is higher than 90% announced, we will trust to the instructions, I do not have the opportunity to check it out. It is equipped with four PCI-Express slots for graphics cards (2 x 6 + 2-pin + 2 x 6 pin) Its dimensions are reduced: 14 cm deep, it is equipped with all electrical protection (OCP, OVP, SCP, OPP, OTP, UVP) and protection against overvoltage and short circuit on all outputs.
