ASRock X370 Killer SLI AC board- Close Up
The ASRock X370 Killer SLI AC motherboard is styled in white and black. The motherboard comes in the standard ATX form factor. As you can tell, the large “K” marking that runs across the PCB is used here to denote the “Killer” series branding. ASRock has another X370 Killer SLI motherboard in their lineup but it lacks the wireless capabilities that the AC offers.
The ASRock X370 Killer SLI AC is designed for the mainstream audience. The board packs a better overall design scheme that allows for faster connectivity, memory support and storage options which the older AM3+ motherboards were lacking. The PCB is of matte black color with white lines textured around the CPU socket.
The board uses the AM4 socket to support AMD CPUs and APUs. The socket is compatible with both AMD Ryzen processors and A-Series APUs. There’s no chance of error while installing a CPU since the socket is keyed, has a 1331 pin layout and won’t support any other chips aside from the ones mentioned by AMD and AIB partners.
The motherboard packs a 12 phase Digi Power PWM supply which powers the socket. The PCB is outfitted with long lifespan, durable black solid state capacitors that have an endurance rating of over 12,000 hours. The powerful VRM design allows overclockers to get the most from this motherboard.
Next to the socket are four DDR4 DIMM slots which can support up to 64 GB (dual channel) memory. These slots are rated to support XMP profiles up to 2933 MHz (OC+).
The VRMs are covered by two sets of heatsinks which are made of aluminum. Both sets are colored in metallic silver and have cuts within them to add to the aesthetics.
The top I/O cover has a Ryzen logo which is a nice touch to the AMD setup. The shield covers the entire I/O panel and looks great on this motherboard.
The ASRock X370 Killer SLI AC motherboard cover on the I/O panel looks decent. There’s no cooling mechanism involved with the cover as it’s just for visuals and mostly hollow from the inside, but it does add to the overall looks of the product and that’s its main purpose here.
The CPU is supplied power through a single 8-pin power connector. This will feed the CPU with up to 150W of power. Most AMD CPUs will be shipping with TDPs under 100W but that changes when users overclock, since that changes the power limit based on applied voltages and clock speeds.
Expansion slots include two PCI Express 3.0 x16 (x16/x8/x4 electrical), three PCI Express 3.0 x1 and two Ultra M.2 slots. The board can support 2-way multi-GPU (CrossFireX / SLI). The M.2 slots are rated to support NVMe PCIe Gen3 x4 SSDs.
ASRock’s X370 Killer SLI AC adopts two PCIe steel slots, which are built with more solder points on the PCB for better performance and preventing any signal interference with graphics cards. This allows your graphics cards to be fed with better quality signals and to be safely and securely installed in the PCIe slots.
There are two Ultra M.2 slots on the motherboard that operate through PCI Express 3.0 x4 link at speeds of 32 GB/s. Both slots are ideally placed. One of them is located at the top of the first PCIe 3.0 x16 slot while the other is situated beneath the PCH with ample room for up to 110mm M.2 drive/memory support.
The X370 PCH is housed beneath a large heatsink with the ASRock logo embedded in it. The cover has a white frame and a large metallic block that is finished in black metal.
Storage options include six SATA III ports rated to operate at 6 Gb/s. These can support 6 different storage devices at the same time.
ASRock is using the Nichicon audio system on this motherboard that has its own audio PCB isolated from the rest of the board. It is a combination of several hardware and software audio solutions. 7.1 CH HD audio with the latest Realtek ALC892 audio codec, individual PCB layers for R/L audio channels, 120dB SNR DAC and other technologies to deliver the crispest sound effects.
The motherboard has two onboard USB 3.0 ports which can be used to connect the front panel. Most current cases can ideally support such ports.
ASRock is using a dual band 802.11ac Wi-Fi module on the motherboard that support 2.4G / 5G Wi-Fi and Bluetooth 4.2. The module is located on top of the first PCIe 3.0 x1 slot.
The I/O on the motherboard includes PS/2, USB 3.1 (Type-A + Type-C), 6 USB 3.0 ports, HDMI, gigabit LAN port and a 7.1 channel high quality audio jack.
