MSI's MEG Z590 ACE, the boards are based upon 18 power phases (16+2), there are 12 real phases managed by an ISL69269 controller. The power stages are all backed by premium 90A MOSFETs, these are then cooled by aluminum heat sinks. The motherboard offers an Intel 2.5 G Ethernet jack (I225-V). This board has WIFI6 (Wi-Fi 6E (WLAN 802.11a/b/g/n/ac/ax, 2x2, Intel AX210), Bluetooth 5.2)
- The board offer a multitude of PCIe slots; 2x PCIe 4.0 x16 (1x x16, 1x x8, CPU), 1x PCIe 3.0 x16 (x4, Z590), 2x PCIe 3.0 x1 (Z590).
- There are six SATA ports and four M2 slots; 1x M.2/M-Key (PCIe 4.0 x4, 22110/2280/2260/2242, CPU), 2x M.2/M-Key (PCIe 3.0 x4/SATA, 2280/2260/2242, Z590), 1x M.2/M-Key (PCIe 3.0 x4, 2280/2260/2242, Z590), 1x M.2/E-Key (PCIe/Intel CNVi, 2230, occupied with WiFi+BT module).
On the rear IO you'll spot 1x HDMI 2.0b (iGPU), 2x USB-A 3.1 (10Gb/s, Z590), 4x USB-A 3.0 (5Gb/s), 2x USB-A 2.0 (480Mb/s), 2x Thunderbolt 4 (Intel JHL8540), 1x 2.5GBase-T (Intel I225-V), 5x jack, 1x toslink, 2x DisplayPort-In (mini DisplayPort).
The onboard audio based on Realtek new leading SKU, the Realtek ALC4082 paired with a DAC (ESS SABRE9018Q2C). You will spot an HDMI video output, and a BIOS Flashback button (an awesome feature that updates firmware without memory, processor, and graphics card installed). This motherboard has been fitted with a 1x 32MB (256Mb) BIOS. it should also be noted that this mobo has the new Thunderbolt chip onboard, 2x Thunderbolt 4 based on Intel JHL8540.
