Specifically, this motherboard:

Alternatively, the product page:

I ask since I remember that you can count the chokes to determine the phases, but what bothered me is that the mobo is advertised as an "8 phase" rather than "4+2" or "8+2". I read from one forum that anything marketed as "8 phase" really was closer to a "4+2" as it only has an extra phase for RAM and GPU, which are useless. Then it being a "4+4" phase really doesn't mean much.

The problem is that I'm not really sure if the "4+4" it's accurate or not. Can anyone confirm if it's likely the case for this mobo?

The number of phases is not determined by the number of chokes, capacitors or pair of mosfets. They're actually determined by the number of mosfet driver chips.

Interesting. Is there a way to tell those chips from the picture I posted?

Don't believe so.

Oh wait, I just compared it to this other motherboard:

And the people on the forum said this blue one has an 8+2 phase. Are the chips you're referring to the ones right above the chokes? There looks to be 20 in total, but I'm guessing that it's more like there are 10 pairs, accounting for the 8+2 phases?

If so, for the red motherboard, does that mean that the mosfet driver chips are underneath those heat-sink grill-looking things?

Yes, the smaller ones are the Mosfet driver chips. However, it's not gonna matter if you have 8 or 10 phase.
