The 12 onboard USB 3.0 ports each carry a single PCIe 1x lane — plug a standard USB-3.0 powered riser cable directly into the board, connect a GPU at the other end, and you have a complete 1x-to-16x mining link.\u003c\/p\u003e\n\u003cp\u003eBased on the Intel B250 chipset and LGA1151 socket, the board supports \u003cspan class=\"mh-highlight\"\u003e6th and 7th Generation Intel Core processors\u003c\/span\u003e (Skylake \/ Kaby Lake) — Pentium G3900, Celeron G3930, and similar low-TDP chips work best for mining since the CPU has minimal load during GPU mining. Two DDR4 DIMM slots support up to 32GB at 2133\/2400\/2666 MT\/s. The board ships with mining mode enabled in the BIOS by default — power on, install drivers, and GPUs are detected automatically.\u003c\/p\u003e\n\u003cp\u003eFor Australian miners building cost-effective GPU rigs, the B250C is attractive because it consolidates the riser-adapter board into the motherboard itself — fewer connection points means fewer potential failure points. Drawbacks: the 6th\/7th Gen Intel CPUs and DDR4 memory are now legacy parts, second-hand availability fluctuates, and the BIOS feature set is sparse compared to BIOSTAR TB360-BTC PRO 2.0. Build cost is typically lower than a TB360 build, but spare-part availability is the trade-off.\u003c\/p\u003e\n\u003cp\u003eStorage includes \u003cspan class=\"mh-highlight\"\u003e4 × SATA 6Gb\/s, an mSATA slot\u003c\/span\u003e, and onboard HDMI output for first-boot configuration.
