Quote: The PWM control for the GPU side is the UPI semiconductor up9511. In this configuration, MSI is using the full 8-phase capability of the uP9511. Memory VRM is controlled by the UPI Semiconductor uP1641. The Sinopower SM7320 Dual Channel MOSFETS help make up the 2-phase memory power delivery. The uP1641 includes two integrates MOSFET drivers (hence no external drivers for the memory MOSFETS) and is capable of two phase. The 10 phase power of this card is 8+2 where 8 phases is used for the GPU and 2 phases are for the memory.
