ASUS seems to be just about ready with a full-fledged lineup of motherboards based on the Intel P55 chipset, that supports LGA-1156 socket CPUs. The newest entry in the company's P7P55 series is the high-end P7P55D Deluxe. The model is placed above the P7P55 EVO and P7P55 Pro, which descend in the same order in the lineup. The P7P55D stands apart with some high-grade components and overclocker-friendly features. The CPU is powered by a lavish 19-phase digital PWM circuit, cooled by chunkier heatsinks that distribute heat among each other using a heatpipe.

The four memory slots supporting dual-channel DDR3 memory are powered by a 4-phase circuit. The user is given greater control of voltages and clock speeds using the TurboV technology. This board even bundles a pop-out wired remote that provides some on-the-fly controls. The expansion slot layout is identical to that of the P7P55 EVO, with three PCI-E 2.0 x16 slots (two of which are electrically x8 when populated, and one is electrical x4). The P55 chipset provides six SATA II ports, while external controllers give out three additional ports. Connectivity and other expansion options include two gigabit Ethernet controllers, over a dozen USB 2.0 ports, Firewire, and audio with digital output. The P7P55D Deluxe could feature in the first wave of P55 motherboards released by ASUS.
