How about the Mini ITX Asus Maximus VIII Impact?
How good is the VRM? Asus uses a separate daughter board for the power delivery. But are the components good?
Is it better than the Asrock Z170 Fatal1ty ITX?

The VRM area at the boards Maximus VIII Ranger, Maximus VIII genes and also at Maximus VIII Hero are very similar. Even when Hero model the Skylake-S CPU is powered by a total of ten coils. Here, however, there are better "MicroFine Alloy Chokes". This in turn receive their input from a respective NexFET MOSFET type Texas Instruments "CSD87350Q5D".


Identical also is the PWM controller "ASP14008" alone does not come with the ten coils cope. But it gets strong support from ten synchronous buck converter drivers. They are derived from International Rectifier and carry the designation IR3535M.

Was it the Z170A Gaming M7 total of 12 + 1 coil, we see here the Z170A Gaming M9 ACK 10 + 1 coil, taking care of the used LGA1151 CPU. Surely only two instead of four coils were drafted so that it remains at eight coils for the core and Uncore area for the integrated graphics unit. Here there is no difference in the MOSFETs used must be held. Again, there are - from the left, narrower coil (for System Agent voltage) apart - per coil once the "PK632BA" and "PK616BA" which originate from NIKOS.

...
The Intersil 95856 is responsible for the control of the eleven coils.

The coils used remember purely visually by the already tested Maximus VIII Ranger and Maximus VIII Gene. Here, however, ASUS titled the 12 coils as "RUF Alloy Chokes". Here, the eight vertically arranged coils around the core area of the processor, the horizontal four coils worry however cover the rest, including the power supply for the integrated graphics unit. In the above picture can be seen very well that each coil is powered by two MOSFETs. These are the models "4C06B" and "4C09B". They are made by ON Semiconductor.
On the whole PCB were "TUF 10K Ti-Caps" capacitors that are to persevere even at unrealistically high temperatures at least 10,000 hours.

The ASP14051 is soldered to most current ASUS motherboards with the Socket LGA1151 and can control up to 12 coils in the 8 + 4 mode according to ASUS. Thus, no phase-Doubler must be used.

At the height of vertical eight CPU eight coils other 4C06B MOSFETs are soldered to the back so that each of the eight vertical coils is powered by a total of three MOSFETs. In the small chip is the IR3535M of International Rectifier. These act as a buck converter and should mainly increase the MOSFET efficiency.

in the foreground are seven coils. Each coil of two MOSFETs of the types "Ra12 T46M" and "RA18-W45K" is energized. They are known better by the term "PowerPAK".
As PWM Controllers Intersil 95856 was used which is sufficient for the project on the GA-Z170X gaming 3

The VRM is striking that the Taiwanese have implemented this range when Z170A Gaming Pro Carbon exactly as it is to be found also in B150A Gaming Pro. Identical are not only the eight "Titanium chokes" and used "Dark Cap" capacitors from Japan, but also the soldered here MOSFETs NIKOS. each a "PK616BA" and "PK632BA" to ensure a good CPU power supply Like most LGA1151 mainboards from MSI also the Z170A Gaming Pro Carbon per coil.

Seems Asrock Z170 Pro4S (and Pro4 according to Anandtech) doesn't use DPAKs , the main difference to the Gaming K4 and Extreme 4 is the lack of USB 3.1 & Purity Sound (also lack of SLI and the Pro 4S also lacks platinum caps)

The Intersil ISL95856 hybrid-digital PWM controller provides 4+3 phases with multiple integrated drivers. To provide all 4+3 phases, GIGABYTE added a few Intersil ISL6625A ("5AZ") to supplement the integrated drivers. Each driver controls the equivalent hardware of two separate phases, so GIGABYTE can market it as 8+3 phases.
....
GIGABYTE is using Vishay SiRA12 for the low-side and SiRA18 for the high-side MOSFETs. These MOSFETs are in the PowerPAK package, and they work just fine on the Z170X-Gaming 7, so I expect the same on the Z170X-Gaming 6.

If you count the phases, this VRM is an 8+3 phase VRM (VCC + VCCGT).

The Intersil ISL95856 is a hybrid digital PWM which has a total of 4+3 phase outputs with three integrated drivers. The CPU VCC (VCore) uses all of the four phases, two drivers are integrated and two ISL6625A labeled (5AZ) are used for the third and fourth drivers. Each driver outputs to two sets of MOSFETs and two inductors.

The power section consists of 11 total phases for the processor.

VRM is a 6+4+1+1 phase VRM
ASRock is using a 4+2 phase PWM which has its phases doubled to 6+4

Intersil ISL95856 is a hybrid digital PWM which has a total of 4+3 phase



Also it seems that the Asrock Fatal1ty Z170 Gaming K4 has the same CPU overclocking ability as the Extreme4


@ Sin0822 , what happened to your VRM table , no Z170 frown.gif
Hardwareluxx is trying to do one but it is poorly filled out http://www.hardwareluxx.de/community/f12/hardwareluxx-z170-mainboard-vrm-liste-update-21-09-15-a-1083516.html

From the photo of the VRM controller, it looks like this one has an ASP1400B. So I take it that it's a 4+2 phase with phase doublers to make it 8+2?

Considering that, does anybody think this board is worth the premium over the cheaper ASUS Z170M-PLUS, with a 4+2 phase VRM, for an i7-6700k build? I don't plan on overclocking (maybe moderate overclocking in the future), but I would (reluctantly) consider paying the premium if it meant better reliability, stability, and longevity, or less heat dissipation etc.

I made a small one, just some boards that seemed interesting to me.
http://forum.chip.de/cpu-board-speicher/faq-cpu-spannungswandlung-1856102.html#post11786489

I think there is no need for those highend designs to overclock a Skylake CPU.
Most of the overclockers might be happy with a GA-Z170X-UD3, a Z170-A or only a ASRock K4, IMHO.

can any one tell me the vrm info of all mother board like high mosfet and low and pwm controler ,driver,doubler i cant find these info even in sinshardware

Do higher end Z170 boards, when overclocked, to lets say, 4.6GHz, require a fan blowing to the VRM area?

You can't say in general.
But if we've got the same definition of 'high end' there should be no need to.
