Motherboard power phases. How much is enough?

[Hybrid_theory]

Looking at the different options of Z77 motherboards. I was initally thinking of the ASUS P8Z77-V LE. But i saw that higher versions of more phases which makes for cleaner voltage going to the cpu.

Now im looking at an H100 Corsair cooler. Am I more likely to be limited by heat? or the voltage in this case?

I would take at least the P8Z77-V with 8+4 phases (8 CPU 4 GPU) if it in the budged.
The ASRock Extreme 4 has 8+4 phases too and is only 140€ here in Finland.

If using IVB CPU, heat will be the limit, even with that cooler. The number of phases should have little effect unless you buy a cheap cheap board(sub-$100), or buy from the wrong OEM, but even so, it's more likely to be BIOS option limitations that you run into after heat, rather than power delivery.
