Design Overview
The MSI MEG X670E ACE uses an AMD AM5 socket that supports AMD Ryzen 8000 and 7000 CPUs. Since different SKUs have different levels of support for PCIe, refer to the user manual for more details. It has 4x DIMM slots. The motherboard has 8 PCB layers using IT-170 Server-grade PCB material and 2oz Thickened Copper. The on-board display coming from the socket includes only a Type-C Display Port capable of 4K@60Hz. In addition, this socket provides 20x PCIe lanes.
Out of a total of 4x M.2 ports, the M.2 Gen 5 is wired to the CPU whereas the rest are wired to the chiplets. This makes sense since all three PCIe slots are Gen5. The bulk of USB connectivity comes from the Chipset or Chiplets. MSI has included an XPANDER-Z Gen5 Dual module that allows the user to install 2x M.2 Gen5 SSDs. This seems to be the first generation since there is no plug-and-play support. Let’s start with the power delivery circuit of this motherboard.
Power Delivery To Socket
MSI is using AMD AM5 platform (LGA 1718). This socket supports the AMD Ryzen 7000 series CPUs out of the box. However, you need to update the BIOS for Ryzen 8000 series CPUs.
MSI has used two extended VRM heatsink covers (Stacked Fin Array Design) along with a heat pipe ensuring a maximum cooling provision for the power stages. The thermal pads are rated for 7W/mK to ensure effective heat transfer.
There is a Gold embellishment on the heatsink cover adding a subtle touch to the overall black theme of the motherboard. This is backlit and can be controlled using MSI Mystic Sync.
The MSI MEG X670E ACE features a powerful delivery circuit using a 22+2+1 phase VRM configuration. MSI has named it DUET meaning that every two stages will get the same PWM signal from the controller. The main driving force is the Infineon XDPE192C3B PWM controller.
The 22 VCore phases are from TDA21490. These power stages each support a maximum of 90 A of continuous current. For the SoC phase, MSI is using two Infineon TDA21472 70A power stages.
There is a backplate for the VRM/Phases on the backside of the motherboard.
DIMM Slots
MSI has used 4x DDR5 UDIMM slots. MSI has used the SMT welding process to install slots on the PCB for better performance. A total of 192GB capacity is supported along with a support for binary as well as non-binary memory kits. The maximum supported DDR5 frequency is 8000+(OC) MHz.
This motherboard supports AMD EXPO as well as Intel XMP with dual-channel and dual-controller modes. The supported memory is non-ECC and unbuffered. In addition, MSI has provided a handy Memory Boost and Memory Extension support in UEFI BIOS that enables the users to leverage the true performance of their DDR5 kits.
Storage Options
This motherboard has 4x M.2 slots and 6x SATA ports. Each M.2 slot or port has an aluminum cover for heat transfer which is finished in black color. The M.2 Shield Frozr tool-less cover is provided over the M.2 Gen5 port.
The overall footprint of this motherboard is quite appealing and eye-catching. Each slot has two thermal pads. One is on the base plate and the other is under the cover. The first and second ports are under a single cover whereas the last two M.2 ports have a single large-size aluminum cover.
I have removed the heatsink covers and shown the M.2 ports. You can see the thermal pads over the base of each slot.
The Gen5 port is located towards the DIMM slot area taking full advantage of the EATX form factor of the PCB. This port also has a thermal pad on the base. The dual thermal pad design makes these drives run cool and faster.
The M.2 Gen4 is wired to the CPU socket. The remaining ports are wired to the chipset. Also, it is interesting to see that only the M2_4 (PCIe 4) slot has 22110 support. The Gen5 does not support this form factor. All these ports conform to Key M.
All M.2 heatsink covers have thermal pads. Speaking of SATA ports, this motherboard has a total of 6x ports. SATA A1 and A2 ports are wired to the ASM1061 controller whereas the rest are wired to the Chipset.
PCIe Connectivity
This motherboard has a total of 3x Gen5 PCIe slots. For Ryzen 7000 series CPUs the configuration of these slots will be x16/0/x4 or x8/x8/x4. This configuration is x8/0/x4 for Ryzen 7 8700G and Ryzen 5 8600G. The Ryzen 5 8500G supports x4/0/x2.
All three slots are wired to the CPU socket. Please note that the PCI_E3 supports up to PCIe 5.0 x4 and it shares a bus with 1x USB 3.2 Gen 2×2 port on the rear panel. Installing a device in PCI_E3 (XPANDER-Z for example) will disable the USB port. You can change the behavior in BIOS.
The top PCIe slot is steel reinforced which MSI refers to as Steel Armor and it has heavy soldered connections on the PCB to support the weight of a heavy graphics card. MSI has used the advanced SMT technology for the PCIE slot to diminish interference and electrical noise.
USB Connectivity
This motherboard is packed with USB ports on the front, rear, and mid-board. It has:
- 4x USB 2.0 (Front)
- 4x USB 2.0 ports (Front)
- 4x USB 5Gbps Type A (Front)
- 8x USB 10Gbps Type A (Rear)
- 1x USB 10Gbps Type C (Rear)
- 1x USB 10Gbps Type C (Front)
- 2x USB 20Gbps Type C (Rear)
- 1x USB 20Gbps Type C (Front)
Thanks to the Chiplet design on the Chipset side, we have more lanes hence more USB connections on the AMD platform. I appreciate the provision of 3 USB 3.2 Gen2x2 ports. One port is dedicated to 60W PD for which you would need to connect a 6-pin PEG connector. This is done via the ITE IT8856FN controller. MSI has used several USB hubs and controllers including ASM1543, ASM1074, P13DPX, PI3EQX10, and PI3EQX2.
Networking Solution
This motherboard packs a powerful 10G LAN port on the rear panel driven by a Marvell AQC113CS-B1-C LAN controller. The wireless connectivity comprises WiFi 6E and Bluetooth 5.2. The module is installed in the M.2 Key-E slot on the rear panel.
The antenna is magnetic making its placement convenient. The WiFi 6E supports MU-MIMO TX/RX and 20MHz, 40MHz, 80MHz, and 160MHz bandwidth in 2.4GHz/5GHz. It supports 802.11 a/b/n/g/ac/ax.
Audio Solution
MSI has implemented Audio hardware on two separate layers of the PCB. They have used RealTek ALC4082 codec in combination with high-performance Chemi-Con capacitors. It is the same codec that I saw on Z790 Tomahawk Max WiFi but MSI has used more capacitors in the ACE motherboard.
There is also ESS ES9280AQ Combo DAC and HPA. This is a 1x 7.1 Channel audio solution that has S/PDIF output as well. It supports up to 32-bit/384 kHz playback on the front panel. MSI has designed the isolated analogy structure for the output on the rear panel. In this design, the external metal housing is separated from the internal layout to further improve the sound quality. The audio solution is the same as I saw in the MEG Z790 ACE MAX.
Chipset
I am showing X670E chiplets after removing its heatsink cover.
Internal Connectors
There are:
- 1x 24-pin Power Connector (ATX_PWR)
- 2x 8-pin EPS Power Connectors (CPU_PWR)
- 1x Front Type-C Quick Charge Connector (PD_PWR1)
- 1x CPU Fan Header
- 2x Pump Fan Header
- 5x System Fan Headers
- 2x Front Panel (JFP) Connectors
- 1x Chassis Intrusion (JCI)
- 1x Water Flow connector

- 1x Tuning Controller connector (JDASH)
- 3x Addressable V2 RGB LED connectors (JARGB_V2)
- 1x RGB LED connector (JRGB)
- 1x TPM pin header (Support TPM 2.0)
- V-check points
- 4x USB 2.0 ports
- 4x USB 5Gbps Type A ports
- 1x USB 10Gbps Type C ports
- 1x USB 20Gbps Type C ports
Each fan header is powered and controlled by nuvoTon 3961S. The same controller was used in MEG Z790 ACE MAX. The Pump and CPU Fan headers are rated for 3A whereas the system fan headers are rated for 2A each.
In addition to Debug LEDs, there are EZ Debug LEDs to troubleshoot the system in case anything goes haywire. These LEDs correspond to the CPU, RAM, VGA, and Boot. I appreciate 2x external sensor ports. The power connectors use solid pins that improve stability by providing low impedance and durability with high current-withstanding capability.
MSI has also provided V-Check read points for VCore and SoC. You would need a voltmeter to read the values.
Rear IO Panel
There are:
- Clear CMOS Button
- Flash BIOS Button
- USB 3.2 Gen 2 10Gbps (Type-A)
- 10G Super LAN
- Wi-Fi / Bluetooth
- HD Audio Connectors
- Smart Button
- USB 3.2 Gen 2×2 20Gbps (Type-C)
- USB 3.2 Gen 2 10Gbps (Type-C Display port)
- USB 3.2 Gen 2×2 20Gbps (Type-C)
- Optical S/PDIF-Out
There is a backplate on the backside that prevents the motherboard from bending and provides an additional cooling surface. I am showing the backside of the motherboard where MSI has provided Transient Voltage Suppressors. These are safety devices that are used to protect against the excessive voltage. In case of abnormal voltage hikes, the TVS switches from a high-resistance state to a low-resistance state hence grounding the excessive voltage.
MSI uses two winband 25Q256JWEQ 256M-bit Serial Flash Memory with uniform 4KB sectors and Dual/Quad SPI. In simple words, these are your BIOS chips.
XPANDER-Z Gen5 DUAL
MSI has bundled an M.2 XPANDER-Z Gen5 DUAL PCIe card with the motherboard. This card has a single fan to keep the SSDs cool during operations. There is a stylish black heatsink cover over the top. This is not a tool-less design as the user is required to open the card and install the SSDs.
There are 4x screws on the backside of the card. Remove these to open the heatsink cover.
I am showing the PCB of the card. There are two Key M type M.2 ports conforming to PCIe Gen5. MSI has provided a plethora of connectors on the PCB making this card compatible with the MSI motherboards. However, the good news is that these are optional except for the 6-pin PCIe connector which is a must. There are:
- JCASE1 header to which you can connect the HDD LED Connector
- JMB1 and JSMB1 allow the user to control the fan’s speed, thermal sensors, SSDs’ stats, and LEDs.
MSI has provided two connector cables for connectivity between this card and the motherboard.
You can control the on-board LEDs using the slider button in addition to the fan control slider button. MSI has used nuvoTon 3974S controller. There is a port for SMART fan control. I detached the cable while removing the heatsink.
There are two thermal pads under the heatsink cover.
BIOS
The BIOS interface is similar to what I saw on the other MSI motherboards that I have tested so far. BIOS starts in the EZ mode. Press F7 to switch to Advanced mode. EXPO/XMP is just one click thanks to user user-friendly interface. CPU, RAM, and Voltage settings are grouped under the OC menu. System-related configuration options are grouped in the Settings menu. Boot and Exit options are also under the Settings menu.
You can control the speed of the fans on the Hardware monitor page. OC Profiles allow the users to save their configurations in the files and restore from the saved files. This would come in handy during installation. M-Flash is used to update the BIOS ROM. Power limits are available in Advanced CPU Configuration.
PBO is your ally when it comes to tweaking and tuning. Performance Switch can be used to access the MSI’s own OC settings. You can also access the thermal point profiles pre-defined in the PBO settings as well as the ECO mode and different TDP settings (PPT/TDC/EDC).
For the software part, you can check it in our Z790 Tomahawk Max WiFi motherboard review.
Test Build
I have used the following configuration to test the motherboard:
