The STRIX series of motherboards for ASUS are characterized by their multi-color (RGB) LED flair over practical mid-segment motherboards. These boards come with headers that simplify RGB LED case lighting using the ASUS Aura software. The company is ready with four such boards, the STRIX Z270H-Gaming and STRIX Z270E-Gaming in the ATX form-factor; the STRIX Z270G-Gaming in the micro-ATX form-factor; and the STRIX Z270I-Gaming, in the mini-ITX form-factor. The Z270H-Gaming is the lighter of the two ATX boards in terms of features, although you still get a 6-phase VRM, two PCI-Express 3.0 x16 slots with SLI support, two M.2 slots, 8-channel gaming-grade audio, and two USB 3.1 ports. The PCH heatsink has a groovy RGB LED ornament. The Z270E-Gaming leads the series, with a 10-phase VRM, 802.11ac WLAN, reinforced PCIe x16 slots, and RGB LED elements located in a large I/O area shroud that extends into the VRM heatsinks.

The Z270G-Gaming is the micro-ATX offering from this lineup. It has more features than the Z270H-Gaming, but fewer slots than the Z270E-Gaming. You get the same 10-phase VRM, and connectivity that includes gaming-grade audio, USB 3.1 ports, two M.2 slots, but no I/O shroud, and the RGB LED element is located in the PCH heatsink. The Z270I-Gaming is brimming with features, including concealed M.2 slot, a reinforced PCIe slot, 8-channel HD audio, 802.11ac WLAN, four SATA 6 Gb/s ports. RGB LED lighting is care of an LED strip located in the reverse side of the PCB, along the right edge of the PCB.
