Yes, you're right. . .the more expensive ATX 2.2 PSU's have both ATX 8-pin and ATX 4-pin power connectors, while cheaper ATX 2.2 PSU's substitute ATX 8-pin with dual ATX 4-pin power connectors. I am guessing that future motherboards will be using this and for that reason I'll buy a 2.2 PSU.
well most intel mobo's use the 8 pin. AMD doesnt. i dont think...havent really gotten into AM2 yet. not a fan. i'd rather buy 939 over AM2, 939 has opterons
