Difference Between Power Phases

[Wtalk2]

Hey LTT, IDK if this is a noob question or not but for a while I have been wondering what power phase designs mean on motherboard or graphics card.

 

For example, my ASRock Z77 Extreme 4 has a 8+4 power phase design and the Asus P8Z77-V PRO has a 12+4 power phase design. Does that mean the Asus has a better power delivery system than my ASRock? Also how does the power phase affect overclocking and what is considered a decent power phase design for the Z77 chipset?

 

Thanks

Put simply, the more the better. More power phases means that there is more power available to the processor allowing more stability under heavy loads or overclocks

I would sit here and explain it to you, but I thought.. Why would I when we have the world wide intrawebs at our disposal.

 

So, here, best answer you'll find:

Thank you very much

 

What would be considered a good power phase for the Z77 chipset?

8+4 is very good. More than enough for a Z77 board

How effective the power delivery system is depends on the quality of the components used, not just the number of them.  In general an 8+2 phase design is good enough if reasonably high-grade components are used.  A large number of phases doesn't necessarily mean the system is better.

The z77 extreme4 is a 4+1 phase vrm not 8+4. http://www.sinhardware.com/images/vrmlist.png

False advertisement. The true phase count is 4+1.

Anandtech lists it as 8+4 http://www.anandtech.com/show/5793/intel-z77-motherboard-review-with-ivy-bridge-asrock-asus-gigabyte-and-msi  given the number of chokes visible on the board I would conker with that.

Pff this guy is collecting a database and has a fair amount of knowledge about VRM: http://sinhardware.com/index.php/vrm-list

He's well known @OCN for this.

It appears you read his chart wrong the Asrock z77 extreme 4 is listed as having 6+1/4+1  I have never seen this form of notation before but I assume he is saying that the vrm is actually split in two one being 6+1 the other 4+1.

Like it says, 6+1 is the pwm phase and 4+1 is the true phase count.
