The X870 LiveMixer WiFi is a full-sized ATX board and has a predominantly dark aesthetic, with heatsinks and shrouds in muted grey/black tones. The overall design is pleasing to the eye and the layout is familiar. ASRock bundles the board with two SATA data cables, a thermistor cable, and dual-band WiFi antennas (covering 2.4 / 5 / 6 GHz) for its onboard wireless module.
The LiveMixer adopts AMD’s AM5 socket which has support for their very latest Ryzen 9000 CPUs. The VRM design is based on a 16 + 2 + 1 phase design with 80A Dr.MOS components for VCore, and SOC.
Our board comes with a good assortment of fan headers which are dotted around, in key areas and they include: 2 × CPU fan connectors (4-pin) 3 × chassis fan connectors (4-pin) 1 × AIO pump connector (4-pin).
On memory, the board supports dual-channel DDR5 across 4 DIMM slots, with a stated overclocking ceiling of 8000+ (OC) and up to a whopping 256GB. In the top-right corner, beside the memory slots we have LED indicators which help to diagnose possible POST issues and there are two addressable ARGB headers.
Also in this area there is a USB 3.2 Gen2x2 front panel header, as well as a USB 3.2 Gen1 front panel header.
Storage is well-covered on LiveMixer Wifi. It offers 2 × SATA3 (6.0 Gb/s) ports. There are also a total of 4x M.2 slots. Two of these M.2 slots support Gen5 x4, and the other two are Gen4 x4 compatible. (One being the smaller 2230 form factor).
There are some lane-sharing behaviours to be aware of: if M2_2 is occupied, the two rear USB4 Type-C ports (and M2_2 itself) will drop to x2 mode unless a BIOS setting changes that (which, however, disables the USB4 ports) Also, occupancy of M2_3 and M2_4 can force reductions in throughput for PCIe slots PCIE2/PCIE3.
Moving to the PCI Express region, there are 3x PCIe x16 slots, one supporting PCIe 5.0 and two supporting PCIe 3.0. The top slot benefits from EZ Release - which is a quick release mechanism for installing/removing graphics cards from the slot.
Audio on the LiveMixer is handled by the Realtek ALC4082 codec, delivering 7.1 channel HD audio. This board also provides support for the Nahimic audio suite, which includes features such as static noise suppression, echo cancellation, voice stabilizer, lateral sound cancellation, and a “Sound Tracker” visual radar to indicate directional audio cues. On the PCB itself, ASRock isolates left and right audio channels on separate layers for better signal integrity
The Rear IO panel is packed with a good assortment of ports to maximise functionality. On this panel we get:
2 × WiFi antenna connectors (for the 802.11be / Wi-Fi 7 module)
1 × HDMI port (HDMI 2.1 / FRL 8G, up to 4K @ 120 Hz)
1 × Optical SPDIF out
2 × USB4 Type-C ports (40 Gb/s)
1 × USB 3.2 Gen1 Type-C port
7 × USB 3.2 Gen1 Type-A ports
6 × USB 2.0 ports
1 × RJ-45 LAN port (Realtek 5 GbE)
1 × BIOS Flashback button
