" ATX12V v2.2
Another minor revision. Added 8-pin connector for PCIe graphics cards, that delivers another 150 watts.

ATX12V v2.3
The most recent revision, effective March 2007. Efficiency recommendations were increased to 80% (with at least 70% efficiency required), and the 12 V load requirement was lowered. Higher efficiency generally results in less power consumption (and less waste heat), and the 80% recommendation brings supplies in line with new Energy Star 4.0 mandates.[13] The reduced load requirement allows compatibility with processors that draw very little power during startup.[14] The absolute over current limit (240VA per rail) is no longer present, enabling 12V line to provide more than 20A per rail.  "
