Now things are getting good.
Broadwell-E uses the same FIVR as its Haswell-E predecessors, and both types of CPUs are supported on this motherboard. On this motherboard, ASUS is providing the FIVR with an 8-phase VRM, and some of the extra pins in the socket are also powered through other converters found elsewhere on the motherboard.
The capacitors are "gunmetal" color 5K "MIL" standard solid polymers, and I am unsure of the inductors, but I would assume they are rated anywhere from 30-50A+, but I am unsure of their exact saturation current. The metal fins on the inductors would hint that they could take advantage of active airflow.
Like in the past, ASUS's PWM is some unmarked PWM; it's labeled "ASP1257". I assume it is an 8-phase digital PWM from International Rectifier. I could not find the datasheet for the power blocks, but they are Infineon BSG0812NDI. Datasheets for the BSG0810NDI, BSG0811NDI, and BSG0813NDI are available from Infineon's website, and the 0810 has the lowest RDS(ON) and the 0813 has the highest, but all of them are rated 50A so I would assume the 0812 is as too, with an RDS(ON) in between those of the 0811 and 0813. Either way, 50A per phase sounds about right for a motherboard in this price range from ASUS.
Since these power blocks are not fully integrated power stages, they require external drivers. ASUS is using eight IR3535 single phase drivers, which reinforces our assumption that the PWM is also from International Rectifier. The drivers are located on the backside of the motherboard and are cooled by a dedicated heat sink.
Both sets of four DIMMs has an identical memory VRM setup. The main DDR4 voltage rail is supplied by two Texas Instruments CSD97374Q4M, high-frequency NexFETs, which have very high efficiency at 15A, continuous 25A output, and peak 60A output. They are controlled by an unknown ASP1250 PWM. The VPP rails are provided by GStek GS9238 single buck converters capable of 8A output.
