I have an Abit AN7 Motherboard (AMD), there are 2 PSU sockets on the board, ATXPWR1 (20 pin) & ATX12V1 (4pin). Do they both have to be connected to the PSU? :-/Yes, the 4-pin supplies 12v to the processor. If your psu does not have the necessary connection then an adaptor CABLE is required to make use of one of the standard 4-pin Molex sockets.


Here is an article from radified.com. You might like to check your psu power rating.

The article from radified.com mentions a P4 board & mine is AMD, my PSU is 400 Watt & has the 4pin ATX12V cable. I used to know whether or not to connect it but I just couldn't remember.Look it up in the MOBO documentation.Here is the word from ABIT UK Tech. Support:

"You do not have to connect the ATX12V one, however, if your PSU has one of these connectors, you can connect it. In theory, that should provide a better power SOURCE to the CPU". 8-)Ajak....... Well there you GO , you have it right from the horse's mouth .....
Your motherboard manual should have contained that information ..... I'm surprised it didn't .

dl65 Instruction manuals, should be called destruction manuals.
