Fortified PCIe slot prevents damage

SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.


ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput, plus electrostatically guarded and surge-protected components for greater tolerance to static electricity and improved protection against surges.

Proven Compatibility

Speed Up with Onboard M.2 Up to 32Gb/s

With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gb/s data-transfer speeds. It is the perfect choice for an operating system or application drive, making your whole PC or professional apps work as fast as possible.

Advanced fan controls

ASUS Prime Z270 motherboards feature best-ever cooling capability, controllable from Fan Xpert 4 Core and from the UEFI. Two modes are available firstly, Auto-Tuning Mode which scans fan parameters and all fans with a single click, and Extreme Quite Mode that reduces the CPU fan speed to below the default minimum, for extra-quiet operation and power savings during light loads.

ASUS Aura Sync technology for distinctive lighting effects

Aura Sync takes RGB lighting beyond the check box, combining and controlling the LEDs of your Aura-enabled products from a single application — so you can achieve perfect, synchronised lighting harmony. Aura lets you sync light effects across your graphics card, Prime Z270-A motherboard, and an ever-growing portfolio of Aura-enabled products.

ASUS Aura lighting control

A well-tuned system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for built-in RGB LEDs as well as LED strips connected to the onboard 4-pin RGB headers — all of which can be synced with an ever-growing portfolio of Aura Sync-capable ASUS hardware.
