Packaging and Overview
I am not so crazy about naming products something like Killer, but some gamers are into it, so it makes some sense. ASRock has gone all in with their "K"iller marketing on the box. The motherboard and accessories are protected in the box by anti-static bags.
The accessory package includes two SATA6Gb/s cables, IO shield, M.2 screw, SLI_HB bridge, driver DVD, case badge, manuals, and even a post card.
The Z270 Killer SLI has four fan headers; all the headers can operate in either DC or PWM mode. The header circled in red is the CPU fan header, and it can supply 1A of current. The other three headers circled in blue are chassis fan/pump headers; they can supply 1.5A of current. I am not sure why the CPU header supports less. Overall, the motherboard's PCH heat sink and "K" silkscreen on the PCB match together, to create a seamless look. Most of the "K" will be covered up by a full sized GPU. I like the white IO and audio shield, it is a nice touch. The back of the motherboard is bare of almost every component, that's a good thing.
The rear IO panel features PS/2 Keyboard/Mouse, five USB 3.0 ports, USB 3.0 type-C, DVI, HDMI, and 7.1 audio outputs with S/PDIF.
Two reinforced PCI-E slots are hooked up to the CPU and operate at x16/x0 or x8/x8. There are also four flexible (open ended) PCI-E 3.0 x1 slots. The motherboard also offers six SATA6Gb/s ports. Two ports are shared with the M.2 slots if you use an SATA M.2 drive.
The motherboard offers two Ultra M.2 ports. They each offer 32Gb/s of throughput. SATA ports 0 and 5 will be disabled if you use an SATA-type M.2 drive.
A single USB 3.0 internal header is located below the 24-pin power connector. At the bottom edge of the motherboard are the front panel headers, two fan headers, and two USB 2.0 internal headers.
An RGB LED header is located at the bottom row of headers on the motherboard to the right of the clear CMOS header. The VRM heat sinks use plastic push-pins while the PCH heat sink uses screws. The IO and audio shield are screwed to the motherboard.
