The difference that could be spotted would be the CPU area. Different inductors from the P5K Deluxe and Nikos MOSFETs are used on the P5K Premium. If you are sharp enough, you would notice a few additional capacitors placed around the board.

A quick look at the rear I/O shows that there is no more PS/2 port for your mouse. Instead, two USB ports have been put in place of the legacy connector. We end up having six USB ports, an optical out, a coaxial out, the remaining standard stuff on ASUS’s higher-end boards, and two eSATA ports.

MOSFETs are found on the bottom of the P5K Deluxe. This can be a problem because there is no airflow to the bottom of the board, and things can get toasty down under when you crank up the speed. However, with the P5K Premium, everything has been placed on the top side only.

 

In addtion, an Agere chip is used for the board�s IEEE1394a capabilities, while 8-channel HD Audio is provided by the Analog Devices AD1988B.

For the Black Pearl Edition, even the rear I/O shield is black in colour, or rather there is a hard sticker pasted on top of the original I/O shield.
