The JINGSHA Mini ITX B75 motherboard supports LGA 1155 CPUs with rare NVMe compatibility for its chipset era. It integrates WiFi 5, USB 3.0, and SATA3 in a 17x17cm form factor, making it ideal for retro gaming PCs or budget NAS systems. Its PCIe 2.0 x4 slot enables NVMe boot via BIOS mods, outperforming typical B75 boards.
How Does the JINGSHA B75 Achieve NVMe Support on LGA 1155?
Through custom BIOS modifications, this motherboard unlocks NVMe protocol recognition despite Intel B75 chipset limitations. Users can boot directly from PCIe-based M.2 drives via a dedicated slot, achieving sequential read speeds up to 1,800MB/s – 3x faster than SATA3 SSDs. The implementation uses partial PCIe 2.0 lanes, balancing performance with legacy CPU compatibility.
What CPUs Are Compatible With This Mini ITX Board?
The motherboard supports 2nd/3rd Gen Intel Core processors (Ivy Bridge/Sandy Bridge), including Xeons like E3-1240 V2. Power-efficient 35W T models like i5-3470T are recommended for compact builds. Overclocking is limited due to chipset constraints, but turbo boost works on compatible i5/i7 CPUs. A Xeon E3-1275 V2 delivers 8-thread performance comparable to modern i3 chips.
| Recommended CPUs | Cores/Threads | Base Clock | TDP |
|---|---|---|---|
| i5-3570 | 4/4 | 3.4GHz | 77W |
| Xeon E3-1240 V2 | 4/8 | 3.4GHz | 69W |
| i3-3240T | 2/4 | 2.9GHz | 35W |
When selecting processors, consider thermal limitations of Mini-ITX cases. The 35W T-series chips like i5-3470T offer the best balance between performance and heat output. For NAS applications, Pentium G2120 provides adequate processing power with 55W TDP. Enthusiasts can utilize Xeon E3-1265L V2 for ECC memory support in server configurations.

Does the Integrated WiFi Support Modern Wireless Standards?
Equipped with a soldered Intel Dual Band Wireless-AC 3165 module, it supports 802.11ac (WiFi 5) with 433Mbps max speed on 5GHz. Bluetooth 4.2 enables peripheral connectivity. While not WiFi 6-capable, it outperforms USB dongles in latency (18-22ms vs 50ms+). External antennas via RP-SMA connectors improve signal strength in metal chassis.
Can This Board Handle 4K Video Playback?
When paired with HD 4000/2500 integrated graphics (i5/i7/Xeon), it supports 4K 30Hz via HDMI 1.4. Discrete GPUs like GTX 1650 can be added through the PCIe x16 slot for 4K 60Hz. Hardware decoding works for H.264 but not HEVC. A Core i7-3770S achieves 25-35% GPU utilization during 4K YouTube playback.
How Does Power Consumption Compare to Modern Boards?
Idle power draw measures 18-22W with a 65W TDP CPU. Under load, systems consume 75-90W – higher than 10th Gen Intel equivalents but manageable with 150W PSUs. Disabling unused features (LAN2, extra USB controllers) saves 3-5W. A Celeron G1610 build consumes just 26W idle, suitable for 24/7 NAS operation.
| Configuration | Idle Power | Load Power |
|---|---|---|
| i5-3570 + SSD | 34W | 89W |
| Xeon E3-1220L + HDD | 28W | 63W |
| Modern i3-10100 | 14W | 48W |
Power efficiency can be improved through BIOS settings like C-states activation and SATA link power management. Using DC-DC power supplies instead of traditional ATX units reduces conversion losses by 10-15%. For 24/7 operation, pairing with a 80Plus Gold PSU brings total system efficiency to 88% at typical loads.
What Cooling Solutions Fit This Compact Board?
Low-profile coolers under 58mm height work best. The Noctua NH-L9i and Cryorig C7 are ideal for i5/i7 CPUs. For passive cooling, a Thermalright AXP-90 with 120mm case fan achieves 65°C on i5-3570 at 100% load. VRM temperatures stay below 85°C with proper airflow, though a 40mm fan on the heatsink improves stability during extended workloads.
“This board fills a niche for enthusiasts wanting modern storage speeds in legacy systems. While not perfect, the NVMe implementation is surprisingly stable – we’ve stress-tested it with 72-hour continuous writes without corruption. The dual LAN ports enable interesting pfSense router builds.”
