Is there any difference in performance with a Higher or lower amount of Power Phase's on a motherboard e.g 12+2 or 8+2 or 24+2 whatever. Or is it just more of a marketing gimmick?
 
Huh?
Do you mean Rails?
Normally manufacturers offer more than 1 'rail'. In other words 12V supplies. Normally splits the load between rails to supply more power when needed. As long as its rated 12v rails are sufficient, then I wouldnt worry.

Or you could be referring to the connectors.

24pin is the main ATX in. (20+4 pin removeable on the psu for older boards)
4 or 8 pin is the CPU suppply where 8 pin means a higher power is required.
and 6+2 is for the graphics cards. Again, the 2 pins are removeable depending on the age / construction of the graphics card.

Its all just pin configurations depending on the amount of power needed from the PSU.
 
Ive heard this being used by asus in advertising their higher end motherboards, the p5q series being a good example. 16 phase on the deluxe, 8 phase power on the p5qe/pro, 16 phase power was supposed to be able to cope better with quads running high fsb.
 
It refers to the power control circuitry changing 12V down for the cpu. The implication is more phases are better.

The evga classified is 8 phase. Draw from that what you will. Personally I translate it as a marketing gimmick, the power circuitry matters, but number of phases is not an accurate reflection of quality.
 
i dont know the things around the CPU socket, whether they are capacitor layouts? I've looked at the mobo descriptions and video's and they say like 12+2 power phase design.
 
Let me explain :)

Phases take into account the elements of the VRM area (Driver, Choke, Mosfet and Capacitor).

The ASUS Xtreme Phase Power Design automatically utilizes more phases to deliver more power. Utilizing more phases actually results in lower average power loading for each phase, allowing more stable power to obtain higher overclocking performance. Xtreme Phase Power also allows ripple voltage to remain more stable – Less fluctuation in current is better!

The ASUS Xtreme Phase Power Design is also able to automatically switch power phases in relation to current loading—ensuring that the overall power supply is stable. With such increased power efficiency stability is enhanced and smoother operations can be obtained under any loading. As well as the added benefit of reduced power loss, lower operating temperatures are achieved. The ASUS Xtreme Phase Power Design can then maximize power, achieving better performance and increased stability whilst enhancing power efficiency and decreasing temperatures under load.

Hope that helps =)
