MS-Terminator B850BKB WIFI: The Next Evolution of MAXSUN BKB Series

In the DIY hardware world, achieving the perfect balance between clean aesthetics and powerful performance has always been the goal for many enthusiasts. To meet this pursuit, MAXSUN continues to innovate and break new ground. The company previously impressed the community with pioneering designs such as the MS-Terminator H770YTX D5 WIFI featuring a revolutionary YTX layout, and the MS-Terminator B760BKB D5 with its back-to-back structure. Both products were praised for their forward-thinking engineering.

Today, MAXSUN takes another leap forward with the debut of the MS-Terminator B850BKB WIFI, a new “BKB”-form motherboard that continues the design philosophy of back-to-back GPU mounting. Through advanced performance optimization, this compact motherboard brings both hardcore power and visual refinement, offering ITX-chassis users a brand-new choice.

As the latest addition to the “BKB” series, the MS-Terminator B850BKB WIFI features a rear-side PCIe graphics slot, allowing the GPU to plug directly into the back of the motherboard — no riser cable required. This design not only achieves a cleaner visual presentation but also reduces latency and ensures a purer, more stable PCIe signal transmission.

The motherboard fully supports MAXSUN’s new PTM BIOS, a fan-favorite among PC enthusiasts. Inspired by smartphone app interaction logic, the PTM BIOS (PC-to-Mobile) adopts a modular and card-based interface, reducing operation layers to no more than two. With an intuitive and focused design, users can effortlessly personalize system settings through a simple, mobile-style experience.

Power delivery has also been enhanced — the board adopts a 6+2+1 phase 110A SPS digital power design, supporting up to 200W TDP. The advanced Smart Power Stage (SPS) technology ensures optimal power output per phase, unlocking stable CPU performance even under demanding workloads.

Despite its compact 171×171 mm size, the MS-Terminator B850BKB WIFI delivers impressive expandability:
– Rear PCIe 5.0 x16 slot + front PCIe 4.0 x4 slot
– Two PCIe 5.0 x4 M.2 slots for ultra-fast NVMe SSDs
– One SFF-8654 4i onboard port and two SATA ports
– Dual Type-C® ports (front and rear) for versatile connectivity
(Actual speeds may vary depending on CPU model. The rear x16 slot supports up to PCIe 5.0 x16, and both M.2 slots support up to PCIe 5.0 x4 operation.)

For memory, it supports dual DDR5 slots with overclocking potential up to 8400 MHz (OC), delivering exceptional responsiveness. In networking, the motherboard integrates 2.5G Ethernet and Wi-Fi 6E wireless, with Bluetooth 5.4 support for modern connectivity needs.

Carrying forward the core strengths of the BKB series while upgrading power, expansion, and stability, the MS-Terminator B850BKB WIFI provides ITX users with a truly compact yet powerful solution. For builders seeking both minimalist aesthetics and hardcore performance, this motherboard stands out as the ultimate choice.
