Introduction and Technical Specifications

With this preview, we give you a quick look at the base level offering from ASUS’ Z170 chipset line, the Z170-A…

Our Intel Skylake launch coverage is intense! Make sure you hit up all the stories and videos that are interesting for you!


ASUS used the introduction of the Z170 chipset and Intel LGA1151 processors to revamp their new motherboard product lines, updating the aesthetics and features with the latest innovations. We are giving you a preview of what to expect from the ASUS Z170 chipset boards, using the Z170-A board provided for evaluation. A more detailed evaluation of the ASUS Z170-A will be released in the coming weeks as we receive evaluation samples from other manufacturers with which we can compare it.

ASUS updated the aesthetics of the channel series boards, changing the previous generation's black and gold design to a much more eye-catching black and white with blue accents. The Z170-A motherboard even comes with an integrated rear panel cover and large black-chromed heat sinks for its VRMs. The board offers full support for Intel's new line of LGA1151 "Skylake-S" processors, paired with dual channel DDR4 memory.

ASUS integrated their latest overclocking technology into the Z170-A motherboard, giving their "entry-level" model the same overclocking potential as offered with their flagship board. ASUS uses a tri-chip design to ensure the board's overclocking capabilities – the Pro Clock control chip, the TPU chip, and the EPU chip. The three chips work in concert to unlock ultra-high frequencies for pushing you Skylake processor to its limits.

The Z170-A motherboard also has the latest ASUS sound technology integrated – Crystal Sound 3. Like its predecessors, Crystal Sound 3 integrates the audio components on a isolated PCB from the other main board components minimizing noise generation caused by those other integrated devices. ASUS designed the audio subsystem with high-quality Japanese-sourced audio and power circuitry for a top-notch audio experience.
