1.1 Power Connector Terminology Change

Technical Product Specifications for ATX and microATX desktop boards referred to the 2 x 2

power connector as the

ATX12V

connector.

With the arrival of BTX form factor desktop boards,

this connector will henceforth be referred to as the

Processor Core Power

connector.
