TPU found a photo and details of the ASUS P7P55 Pro. As the name suggests, this is an upcoming P55 based motherboard for the Intel Core i5.
The LGA-1156 socket CPU is powered by an 8+2 phase power circuit. Four DDR3 DIMM slots support dual-channel DDR3 memory, and use the click-slot retention mechanism the company experimented with, on the Rampage II Gene. The DIMM retention notches are available only on one side of the slot, creating uninterrupted room for a PCI-Express graphics card.
The board provides two PCI-Express 2.0 x16 slots (electrically x16, x4), two PCI-E x1, and three PCI slots. The P55 PCH provides six SATA II slots, while an extra one, along with an IDE channel and an eSATA port are provided by an external controller. 8-channel audio and gigabit Ethernet make for the rest of the mix.
