Maxsun Unveils iCraft X870M mATX Motherboard with Support for Next Gen AMD Ryzen CPUs and Unlocked 400W TDP
Maxsun has introduced one of its most aggressive and feature rich micro ATX AM5 motherboards to date with the debut of the iCraft X870M, a compact board engineered to handle current and next generation AMD Ryzen processors while supporting an unlocked TDP ceiling of up to 400W. This positions the board squarely toward high end enthusiasts, overclockers, and performance driven builders seeking mATX form factors without compromising power delivery or expandability.
According to Maxsun, the iCraft X870M is fully compatible with Ryzen 7000, Ryzen 8000, and Ryzen 9000 CPUs and is already validated for upcoming AMD Ryzen generations. At the core of the design is a 16+2+1 phase VRM architecture built with 50A DrMOS power stages providing robust, stable delivery for top tier processors such as the Ryzen 9 9950X3D. Maxsun states that while the board officially supports 300W TDP, it includes an unlocked 400W capability to allow future high wattage chips and extreme performance tuning scenarios.
Memory support includes four DDR5 DIMM slots accommodating up to 192GB with speeds reaching 8400 MT/s OC alongside AMD EXPO readiness. Expansion capabilities are equally competitive featuring a PCIe 5.0 x16 slot for next generation GPUs and three M.2 slots including one PCIe 5.0 x4 and two PCIe 4.0 x4. Notably, one of the M.2 slots is positioned on the rear of the board while the front facing slots benefit from cooling via both a heatsink assembly and the X870 chipset fan which also helps reduce thermal load from the GPU.
Rear and front panel connectivity is a standout element of the iCraft X870M. The rear IO includes two USB4 40Gbps ports, six USB 5Gbps ports, and two USB 2.0 ports, while front IO support includes one USB C 10Gbps, one USB 5Gbps, and two USB 2.0 headers. Networking and wireless support are next generation as well with WiFi 7, Bluetooth 5.4, and a 5GbE LAN port. For audio, Maxsun integrates the Realtek ALC1220 codec with five analog jacks and S PDIF for high fidelity output.
Practical DIY enhancements include a GPU Quick Release mechanism, Clear CMOS button on the rear panel, a snap on antenna design, reinforced PCIe slots, and a top lane PCIe x16 slot placement optimized for compact case installation. The design also introduces MAXSUN VIEW, an onboard customizable display providing real time system information and aesthetic personalization options.
The motherboard is further complemented by the PTM UI BIOS, Maxsun’s newly redesigned firmware interface offering a streamlined user experience without sacrificing the depth required by advanced tuners and overclockers.
Core highlights include:
16+2+1 power stages with 50A DrMOS for uncompromised stability under 300W–400W loads
MAXSUN VIEW onboard display with customizable system readouts
Three PCIe 5.0 M.2 slots and dual USB4 40Gbps Type C ports
WiFi 7 and 5GbE LAN for ultra low latency gaming and streaming
New generation PTM UI BIOS
Reinforced PCIe slots and extensive ARGB support
With AM5 continuing to expand and motherboard vendors introducing increasingly feature rich platforms, Maxsun is clearly positioning the iCraft X870M as a competitive high end mATX solution that rivals some full size ATX offerings. Pricing has not yet been disclosed, though current market indicators place it in the USD 250 to 300 range.
