I have just been helping a friend build his PC using some of my old bits, including an Antec 430W True Power PSU.
This PSU has a 20 pin power connector to the mobo, however the board that he just bought was the Asus P5B Deluxe wit 24 pins. The only was to insert the plug was to the bottom 20 of the 24 pins and the PC seems to have powered up and is working without the top 4 pins having power.
Can anyone please explain if this will be a problem? I am not sure which part of the system takes its power from the top 4 pins of the 24 pins on the mobo. If necessary he'll get a new PSU, but would like to know in advance what this is for.
Thanks
