MSI MEG Z690 Ace DDR5 Intel Motherboard

The MSI MEG Z690 Ace is a flagship E-ATX motherboard built around the Intel Z690 chipset, designed to support 12th Generation Intel Core, Pentium Gold, and Celeron processors in the LGA1700 socket. Its E-ATX footprint measures 12 in. x 9.6 in. (30.5 cm x 27.7 cm), providing ample room for an expansive feature set suited to high-performance desktop builds. At the heart of the power delivery is a 19+1+2-phase design using 105A Smart Power Stage components, Titanium Choke III inductors, and dual 8-pin ATX 12V CPU power connectors, ensuring stable voltage regulation even under sustained heavy loads. Thermal management extends to an aluminium VRM cover with an integrated heat-pipe, 7 W/mK thermal pads, and a double-sided M.2 Shield Frozr that covers all five M.2 slots — helping to keep NVMe drives from throttling during extended use. Memory support is handled by four DDR5 slots capable of holding up to 128 GB total. JEDEC-rated base speed sits at 4800 MHz (1R), while XMP 3.0 overclocking profiles allow single-DIMM-per-channel configurations to reach DDR5-6666+ MHz. The board uses an SMT DDR5 slot design alongside MSI's Memory Boost and Memory Force tuning utilities. Connectivity is a standout area. Two Thunderbolt 4 ports (Intel JHL8540 controller) on the rear panel each support 40 Gbps transfers with Thunderbolt devices, daisy-chaining of up to three TB4 or five TB3 devices, and 8K display output via the board Mini DisplayPort input passthrough. Wireless is handled by an Intel Wi-Fi 6E module (pre-installed in the M.2 Key-E slot) supporting 2.4 GHz, 5 GHz, and 6 GHz bands at up to 2.4 Gbps with MU-MIMO TX/RX and Bluetooth 5.2. Dual Intel I225V 2.5 Gbps wired LAN controllers round out the networking options. Expansion includes three PCIe x16 slots: PCI_E1 at PCIe 5.0 x16 (CPU), PCI_E2 at PCIe 5.0 x8 (CPU), and PCI_E3 at PCIe 4.0 x4 (chipset). Storage spans five M.2 Key-M slots and six SATA 6 Gb/s ports, with M.2 speeds up to PCIe 4.0 x4 on four of the five slots. RAID 0, 1, 5, and 10 are supported for both SATA and NVMe arrays. Audio is managed by a Realtek ALC4082 codec paired with an ESS SABRE9018Q2C combo DAC and headphone amplifier, delivering 7.1-channel HD audio with optical S/PDIF output. The 8-layer PCB features 2 oz thickened copper for signal integrity and long-term stability. RGB and addressable lighting headers include one 4-pin RGB, two 3-pin RAINBOW, and one 3-pin Corsair LED connector, all manageable via MSI's Mystic Light ecosystem. A 2-digit debug LED and four EZ Debug LEDs aid troubleshooting. MSI provides a 3-year warranty.
