What is ATX 2.2?

It is to my understanding that a lot of ATX 2.2 PSU's have two 4-pin ATX12v power connectors, whereas most ATX 2.0 PSU's have only one. If this is true, why is this so? Will we need ATX 2.2 PSU's for Conroe motherboards? What kind of PSU's will we need for Conroe anyway (will be getting E6400 system)? Thanks.

    i believe 2.2 has the 8 pin power connecter.
  2. 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 :)
  4. I see. Since I intend to buy an E6400, I suppose it's safe to get 2.2. Thanks for the help :)
