The CPU voltage regulator circuit of the MSI FM2-A85XA-GD65 has six phases for the CPU main voltage and two for the CPU memory controller (“CPU-NB”). Therefore, it uses a “6+2” configuration. The voltage regulator is controlled by an IR3567A integrated circuit, using a digital design.
MSI used military-grade components on the voltage regulator circuit of the FM2-A85XA-GD65. Electronic components rated as military-grade have a higher operating temperature range, tighter specifications, and higher life-span. All capacitors used on the voltage regulator circuit are SMD (Surface Mount Devices), also known as highly-conductive polymerized or simply Hi-c.
All coils used on this motherboard are solid ferrite coils, called “Super Ferrite Chokes” by MSI. According to MSI, these coils work 20° C cooler than traditional coils. Capacitors used outside the voltage regulator circuit are solid.
