Well since I am buying from a store where they actually merge all parts in case, I could prolly require from them to update motherboard bios so kabylake would work. Reason why I am not going B150m is simply to save few bucks, mainly I wanted to go with Mortar Msi B150m(it has 4 DDR4 slots while H110m only 2) but it costs almost twise the price of H110m, H110m has the the all features I need, except it has only one 4pin for case coolers while B150 has 2. I think that issue can be overwriten simply by getting a hub(at least thats what I heard, dunno if it's safe. So if I decide to go H110m mobo, should I go Asus/Msi or Gigabite with 2 fewer phases?
On Power Phase
Assuming you got an H110M to work with the Kaby Lake CPU, the number of power phases does
not matter
since you'll only be using a locked CPU with a low-TDP (i.e., low heat and low power consumption). The
higher number of phases
does lessen the load/stress of each of the other phases when converting the +12V power supplied from your PSU to the required voltage going into the CPU/RAM/MB, however, this is only beneficial/evident
if you are overclocking or using a high-TDP CPU. So, with 6 PP vs 4 PP, that 2-phase difference is
not a grave concern especially in running a non-OC'able/locked CPU with only a 65W-TDP.
Which Motherboard?
The choice of motherboard entirely depends on your
required connectivity and features. Among the motherboards mentioned, all are
very similarly spec'd (i.e., all have 2x RAM slots, 1x PCIe3.0 x16 slot, 2x PCIe2.0 x1 slots, 4x SATA ports, 3x Audio Jacks, same Audio Codec, same LAN Controller, 2x fan headers, etc.).
If you need
PWM fan headers for your case fans, you should get the Asus as it has 2x fan headers that are both 4-pin PWM headers. Msi and Gigabyte, have only 1x PWM header (the CPU_FAN), despite having all headers as 4-pin headers, the 1x case fan header is actually a DC header (voltage-controlled) only.
If
number of USB rear panel ports is a concern, the Gigabyte only has 4x (2x USB3.0 + 2x USB2.0) while Msi and Asus have 6x (2x USB3.0 + 4x USB2.0). If
number of USB internal headers matter, the Gigabyte offers 3x Internal USB Headers (1x USB3.0 + 2x USB2.0) while Msi and Asus only offers 2x Internal USB Headers (1x USB3.0 + 1x USB2.0).
If you need
legacy ports (old ports for older interfaces):
Asus has 1x PCI slot, 1x Serial and 1x Parallel Headers on-board and 2x PS/2 ports and 1x Serial Port at rear panel;
Gigabyte has 2x PS/2 ports, 1x Parallel Port and 1x Serial Port at the rear panel; and
Msi has 1x Serial Header on-board and 1x PS/2 port at the rear panel.
There's also a
slight difference in
size (if it matters to you on looks), despite all being mATX in form. The Asus is the largest at 244mm x 182mm; the Msi is 235mm x 180mm; the Gigabyte is the smallest at 226mm x 174mm.
Aesthetics, esp. if you are using a window panel case, might also be considered as both Msi and Gigabyte are Black-Gray while the Asus is Black-Gray with Gold accent (the chipset).
In terms of
features, the Msi has the Debug LEDs (for CPU, RAM, and GPU) for diagnostics and Reinforced PCI slot (to prevent breakage due to heavy GPUs); the Gigabyte has the DualBIOS (exclusive feature for safe BIOS updating in case of failure); Asus doesn't have any of these features based on specs.
