修改了一些东西,包括CPU Support Power / efficient .......

ATX Power Version http://en.wikipedia.org/wiki/ATX

Some new CPUs consume almost zero wattages when the system is first turned on. And this is why some 2.2 spec PSUs might not power up the system. With Spec 2.3 PSUs the 12V CPU load requirement has been reduced to resolve this issue.

Yea, some 2.2 spec PSUs are really efficient. Intel's 2.2 spec only recommends a 75%+ efficiency for the 2.2 spec though. The 2.3 spec however recommends a 80%+ efficiency. If you getting a new PSU get one that's 80 PLUS certified.

2/3 : 20-pin ATX / 24 pins (Extented ATX)
以前Power 是 20Pin的,后来CPU "需求无度"
因此增加到24Pin供应电源,所以旧的主机板20pin
后来一点的主机板,为了相容增加4pin接头,让20pin
的Power可以用,现在都是24Pin的power了................
