Z170X-UD5 TH in its birthday suit.
The main CPU VRM only powers the VCC and VCCGT, and the VCCSA and VCCIO are derived from a linear regulator located right below the CPU socket. The VRM is an 8+3 phase (VCore+iGPU) powered a 4+3 phase VRM. The inductors have a fancy logo on them and are part of a custom batch of inductors seen on some other GIGABYTE boards. The capacitors are custom made 10K Chemicon black solid polymer capacitors.
GIGABYTE uses an Intersil ISL95856 hybrid-digital PWM that supports a maximum of 4+3 phases of output. While the PWM provides 2+1 integrated drivers, four extra Intersil ISL6625A labeled "5AZ" are needed to utilize all the PWM's phases. These four drivers are located around the VRM, and each driver for the iGPU phases is directly connected to one pair of MOSFETs while each driver for the VCore phases is connected to two pairs of MOSFETs.
The MOSFETs are from Vishay Siliconix. Each phase uses a SiRA12 and a SiRA18 TrenchFET for the low-side and high-side. The VCCIO and VCCSA are powered by a linear regulator located below the CPU socket.
The memory VRM is powered by a single phase PWM with integrated drivers, the Richtek RT8120. The single phase VRM utilized two SiRA12 for the low-side and a single SiRA12 for the high-side.
