I had to look all this up about a month ago.  He is what I found:

ATX     -> 20 pin
ATX12V  -> 20 pin ATX & 4 pin +12V
EPS12V  -> 24 pin (ATX + +12V)
BTX     -> 24 pin

The ATX12V 20 pin and 4 pin connectors can be plugged in together into 
an EPS12V motherboard socket.

BTX is not compatible with EPS.
