Overall, the MSI MPG Z690 CARBON WiFi is optimized for Intel Core i9-12900K, offering DDR5 support, PCIe 5.0 connectivity, and a robust VRM design with competitive thermals.

2. MSI Z690 FORCE WiFi

MSI Z690 FORCE WiFi is an ATX motherboard based on the Intel Z690 chipset, designed for Intel Core i9-12900K processors. Unlike the MSI MPG Z690 CARBON WiFi, this motherboard has a white and silver heatsink design, which matches better with white PC cases. Its performance level is comparable to the Carbon model, but it is typically priced around $20–40 lower, depending on the retailer. The board features ARGB lighting on the I/O cover and chipset heatsink, which enhances the aesthetics of the white-themed build.

The overclocking capability is identical to the CARBON WiFi model because it also uses an 18+1+1 phase VRM design with 75A Smart Power Stages for Vcore, iGPU, and AUX rails. The cooling solution includes enlarged aluminum heatsinks and a 6-layer PCB, ensuring stable performance under high loads. You also get advanced I/O functions, including Audio Boost 5 with an isolated audio PCB, 2.5G LAN with Intel Wi-Fi 6E, PCIe 5.0 x16 slot with Steel Armor reinforcement, and eight rear USB ports, including USB 3.2 Gen 2×2 Type-C.

The memory overclocking support reaches DDR5-6666 MHz (OC) across four DIMM slots with a maximum capacity of 128 GB. This model does not include DDR4 support, making it suited only for DDR5 kits.

3. ASUS ROG MAXIMUS Z690 HERO

ASUS ROG Maximus Z690 Hero is a high-end LGA1700 motherboard designed for enthusiasts who overclock Intel Core i9-12900K. It combines premium aesthetics with 20+1 VRM power stages rated at 90A, delivering stable performance under heavy loads. This model is also among the most expensive Z690 chipset motherboards, reflecting its advanced design.

The motherboard supports DDR5 memory up to 6400 MHz and offers PCIe 5.0 slots for GPUs and NVMe drives. For overclocking, the 20+1 teamed power stages ensure sustained current delivery, making it more capable than mid-range Z690 boards like the ASUS TUF Gaming Z690-Plus (16+1 phases). Connectivity options include Dual Thunderbolt 4 ports, Wi-Fi 6E, HDMI 2.1, multiple M.2 slots, and the ROG Hyper M.2 expansion card.

In conclusion, ASUS ROG Maximus Z690 Hero is one of the strongest options for overclocking the Intel Core i9-12900K, offering DDR5-6400 support, PCIe 5.0 expansion, and extensive connectivity, if you are willing to invest in its premium price.

4. ASUS PRIME Z690-A

ASUS PRIME Z690-A is a mid-range Z690 motherboard designed for Intel Core i9-12900K and users who want reliable VRM performance at a lower price. The average cost is around $280, which is 20–30% lower than ASUS ROG STRIX Z690 models, and it is widely available in the market. The white heatsink design with integrated RGB lighting appeals to users building white-themed PCs.

The overclocking performance of this motherboard is sufficient to handle i9-12900K all-core loads up to 5.1 GHz, although it does not reach the 5.3 GHz levels of ROG STRIX Z690 boards. The motherboard uses a 16+1 phase VRM with DrMOS power stages, which is adequate for high-end gaming and productivity workloads. The memory clock rates of the motherboard are strong, supporting DDR5 modules up to 6400 MHz. The I/O features of the motherboard are limited compared to ROG STRIX boards but still include HDMI 2.1, DisplayPort 1.4, USB 3.2 Gen 2×2, and PCIe 5.0 x16 for GPUs.

5. GIGABYTE Z690 AORUS ULTRA

GIGABYTE Z690 AORUS ULTRA is a performance-focused motherboard on the list, and this motherboard is designed for functionality with a black PCB and RGB lighting, but fewer aesthetic customizations compared to ASUS ROG and MSI CARBON models. The performance of this motherboard is within 2% of MSI MPG Z690 CARBON WiFi in Cinebench R23 and around 8% higher than MSI PRIME Z690-A, which provides a measurable advantage.

The overclocking performance of this motherboard supports stable overclocking of the Intel Core i9-12900K when paired with a 360mm AIO cooler. The motherboard uses a 16+1+2 phase VRM with 105A power stages and large heatsinks, keeping VRM temperatures below 70°C under load to prevent thermal throttling, which is why you won’t have any overheating issues with power delivery. The motherboard supports DDR5 memory, and the maximum supported memory clock rates are 6200 MHz with up to 128GB capacity, which is 400 MHz higher than MSI PRO Z690-A and comparable to ASUS ROG STRIX Z690-E.
