Mobo powerphases explain please!

[Marie Rose]

Motherboard power phases what's the best one out of these? 8+1+1 phase power supply vs 7+1+1 vs Hybrid 6+2+1 Phases.
I got no idea what this means. Lga 1700 boards. Will be using 12400f.

Terminator B760M GKD5 (maxsun.com) 8+1+1

ASRock > B760M-HDV/M.2 7+1+1
B760M GAMING (rev. 1.2) Key Features | Motherboard - GIGABYTE Global Hybrid 6+2+1

More phases is one way to get better voltage regulation, though there are diminishing returns above ~8 stages. More phases is also one way to get extra efficiency and therefore lowering the temperatures of the motherboard VRM, though the specific components used and the heatsinks used also play a pretty major role in VRM temps. 

 

The phases are listed as the VCORE+VCCIN+iGPU VRMs respectively. VCCIN and the iGPU draw basically no power, so these can be largely ignored when compared to the massive amount of current the VCore VRM has to handle. 

 

 

Out of those three boards you listed, the Maxsun Terminator is the best. It has the largest heatsinks with the most surface area, it has the best components per phase (50A DR MOS components rather than the cheaper and less efficient low/high side MOSFETs the other two boards use), and has the most power stages to spread the power losses over. Granted, with a 12400F, all three of these boards should be fine since that chip doesn't use much power, but if they're all the same price you might as well get the best of the three. 

 

It might be worth looking to see if you can get a B760M PG Riptide, it's usually pretty cheap, has a better VRM than all three of those boards, and supports overclocking the 12400F for even more performance.

It really doesn't matter for a person like you.

 

The number is not relevant ... because the quality of the components in a phase also matters.  For example, you can have 6 phases each capable of 80A of current, or you could have 8 phases each capable of 50A of current ... doesn't mean the 8 phase version is better.

 

12400f is a low power cpu, which consumes something like 90-100 watts at 100% on all cores.  That's nothing for a VRM... don't worry about it.

 

The Asrock is probably the crappiest out of the bunch,  strictly based on heatsink on VRMs, connectors on the IO shield etc ... has the extra m.2 for wifi card as a bonus other than that ...

 

Gigabyte is same as Asrock, no difference in features (except lack of the m.2 wifi connector), just slightly better heatsinks on VRM.

 

The Maxsun is nicer, the heatsinks on VRM look bigger but that can be misleading, as they're connected to the IO shield plate so the airflow around that area can be less optimal.  That board also gives you that USB 10g header which could be useful if you get the right case, also has m.2 slot for wireless and holes in the io shield to add antennas so it could be good to cheaply add wireless to your mobo.

Problem I'd have with a board like this is that as it's less popular, smaller manufacturer, you may not get bios updates as often as with the others, or if there's some quirk with it, you would have a hard time replacing it / dealing with warranty etc etc and would have slightly less resale value if you'll decide to sell it later.

 

So for your needs from what's best in term of features  .. maxsun > asrock > gigabyte  ...  

 

In terms of what I'd buy for me if stuck choosing between the 3 .. gigabyte > maxsun > asrock

On top of power phase requirements, the other features of the motherboard are important. Don't put your blinders on and only focus on one aspect of it. All of it comes together to form a specific product. If you focus on one aspect, you may end up shooting yourself in the foot in other areas.
