ASUS P9X79 Deluxe

While the Sabertooth X79 is built for extreme heat, the P9X79 Deluxe is simply ASUS’ top board in its mainstream line, which is to say that it’s no slouch.

The P9X79, with a black PCB and blue, white, and metallic components, supports up to 64GB of DDR3-2400 (OC) memory and up to 3-way SLI or 4-way CrossFireX (at x8). There are four total PCI-E 3.0 slots, as well as a pair of PCI-E 2.0.

The P9X79 Deluxe has eight total SATA ports: six are from the chipset (two SATA 6Gb/s, four SATA 3Gb/s) and two (both SATA 6Gb/s) are courtesy of a Marvell controller. Two of those ports support ASUS’ SSD Caching. There are two additional power eSATA 6Gb/s ports, as well.

There is no shortage of USB ports, either; the board has no fewer than ten on the back panel (six USB 3.0, four USB 2.0), which are conveniently clearly labelled, with headers supporting another ten (two USB 3.0, eight USB 2.0).

On-board buttons include power, reset, Clear CMOS, and MemOK (which validates and patches RAM) on the main PCB, with a BIOS Flashback button on the back panel. The BIOS Flashback button allows you to flash the BIOS using a USB drive with nothing more than standby power. ASUS also included physical TPU and EPU switches, which enable technologies that take some of the burden off of the CPU intelligently managing or boosting power, or to conserve power when not needed.

The TPU and EPU are part of ASUS’ DIGI+ Power Control, which includes three digital voltage controllers for more granular fine-tuning of memory and the CPU.


With BT GO 3.0!, users get a module that supports both Bluetooth and WiFi, and ASUS included a pair of white antennae for the WiFi.

ASUS is serious about giving users as much control as possible by making almost every aspect of the system changeable in the BIOS. This includes Fan Xpert+, which lets users adjust the speeds on all attached case and CPU fans according to a number of different user-customizable parameters.

Having so much control is great for overclockers, but ASUS also included AI Suite II, which automatically boosts the system but allows users to change settings, in case they wanted to let some software do most of the tweaking.
