MSI uses its own design for this board, which is also significantly different from the MSI GTX 1080 Ti Gaming X. The three 8-pin sockets for the external power supply are followed by three coils in the entrance area for smoothing the tips, as well as a shunt.
MSI relies on a design of 7+3 phases, doubling the 7 phases for the GPU. For example, two control circuits are available in parallel by 180° phase-shifted control circuits per phase. The three phases for the memory are to the right.
The back looks tidy and houses, among other things. PWM controller for memory.
