M5A97 Evo R2.0 - how many phases in reality?

[Necrus]

Hello,

could you please explain how many digital power phases has in reality the mobo mentioned in the title.
I went to description nad it was said that 6+2.

But then on an Asus page there is a pic:

saying that there is 6+2+2 Digital Power Phases.

Could you please explain what does it mean? And how many phases are there in reality (I am planning small OC on my FX-8320).

read the overview but first.
your power supply takes ac current from the wall socket and converts it to dc current in to voltages 3.3, 5 and +12 -12 volts.near your cpu here is a 4pin connector that supply's 12 volts to your cpu and ram. although the cpu and ram do not operate a those voltages that's about 10 x more than the operating voltages.in order to be able for those components to work we need to take that 12 volts and turn it to whatever voltage the cpu and ram needs to operate.
this is achieved with the use of power regulators.it takes 12 volts and turns it in to the voltage that we need it to be in order for the components to work.(i am not specifying voltages because they vary depending on what components you have).
when the power supply gives us 12 volts there is a slight ripple like a waveform and the the voltage fluctuates.
the power regulators not only lower the voltage but pass them through a series of "smart digital" voltage regulators to eliminate most of the fluctuation.in this case of this motherboard the 12 volts pass through 6 phase power regulators.

OK. Thanks for the explanation, but then another question - what is the difference between this system, and those 8+2 which are being brought with the more expensive mobo's? F.e. Asus 990FX Sabertooth.

this should help.
better efficiency,less fluctuating voltages ,and better overclocking.
