1. The B75 USB-BTC motherboard uses all-solid capacitors to make the motherboard more stable; it supports LGA1155 CPU and uses the B75 chipset to give full play to the CPU performance2. Innovative design, convert PCIE 1x directly to USB3.0 interface, reduce intermediate transmission links, reduce costs, reduce signal attenuation, and make continuous long-term work more stable.3. 8-port USB 3.0 interface: With the plug-and-play function, you can instantly experience the data speed 10 faster than USB 2.04. The motherboard of B75 mining machine has low power consumption, low calorific value, energy saving and power saving. The actual work done is lasting and rewarding.5. The motherboard is low in and in expansion interfaces, suitable for the mining industry.(1) Display interface: 1*-compatible, 1*VGA(2) USB rear: 2*USB2.0(3) USB front: 1*USB2.0(4) USB rear: 2*USB3.0(5) USB front: 1*USB3.0(6) interface: 4*SATA(7) Graphics interface: 8*PCIE1X (USB )(8) Network card interface: 1*LAN 100M network card(9) Memory slot: 2*DDR3(10) CPU socket: LGA (1155)(11) Chipset: BGA (B75)(12) interface: 1*MSATA(13) BIOS initial restoration: JCMOS(14) Speaker interface: 1SPK(15) Power interface: 24pin_ATXPWR(16) Power interface: 4pin_ATX12VCPU type: Support For 1155CPU socket: LGA_1155CPU model: G530/G540/G550/ G620/G630/G640 /G1610/G1620/G1630 Random CPUMemory type: support 2*DDR3Maximum memory capacity: support a of 16G, a single maximum of 8GMemory description: support 1333/1600MHz frequencyChipset: For B75 ChipsetAudio chip: N/ANetwork card chip: 1*REALTEK 100M network cardProduct size: 230 x 175mmMaterial: PCBcolour: blackPackage Contents:1 x B75 motherboard1 x random CPU(Note: Random CPU, ' accept the specified CPU.)1 x SATA cable1 x switch cable1 x thermal grease1 x RJ45 network cableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
