What the hell is 8 phase power design?

I have been looking around on google for a decent answer and I've yet to find one. Is it anyway related to 3 phase power? But instead of being 2pi/3(120o) it's pi/4(45o) phase difference or am I completely confusing myself with unrelated topics?

Phase power design is a general indication of how stable, clean and beefy the power delivery is to the CPU/RAM (By MOSFETs and VRM's)

 

A very common power phase design is 8+2

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

But in same time it does not mean that if those are "weaker" stabilizers.

Manufacturers should say which are they using beside how many.

Thanks for adding a link to the article you found helpful, this should be done more often :)

Bleigh!  Ever hear of AC series?

Most common board are 6 - 8 phase. 

 

Overclocking boards are usually 16 - 32 phase.

16 phase

20 phase

32 phase

But then why are ROG boards only 8 phase? Is it becuase the VRM is beefier

As far as I know, a power phase is a buffer between the power supply and the component that needs the power. if you have 2 power phases (like gpu memory for example), it means the required power is being split in 2, and then rejoined before reaching the component.

 

if you have 8 power phases (maybe for the GPU die itself, I dunno what the standard number is), then the same applies, where the amps/charge is split 8 ways before being rejoined to power the gpu.

 

 

how many phases there are doesn't account for quality of capacitors, or other potential points of failure.

 

(edited because I was partly wrong)
