Phase power?

[iamajunky]

Can someone explain to me what it means when someone says like phase 3 power or something like that for video cards

[calvary1980]

some cards like Asus, Galaxy, Gigabyte, Palit, Vvikoo and eVGA use 3 phase power that consists of 3 transistors that look like this (http://img516.imageshack.us/img516/852/img0118ml8.jpg) it allows the card to remain a little cooler, more stability and higher overclock. reference cards use 2 phase power.
