19-Slot Mining Motherboard
ASUS B250 Mining Expert is the world's first mining motherboard to feature 19 PCI Express® (PCIe®) slots. With 18 PCIe x1 and one PCIe x16 slots on board, plus three zoned ATX12V power connectors, B250 Mining Expert lets you run up to 19 NVIDIA or AMD GPUs in parallel to max out your megahash rates.

Triple-ATX12V Power Delivery
B250 Mining Expert has been engineered to provide all the power your GPUs demand, cleanly and efficiently. The 19 PCIe slots are grouped into three distinct zones, each powered by its own, dedicated 24-pin ATX12V power connector — reducing wiring complexity and ensuring ample power delivery to all PCIe slots.

Voltage-Stabilization Capacitors
Stable, low-noise power is a serious benefit for 24/7 cryptocurrency mining. That's why we've engineered B250 Mining Expert with 19 decoupling capacitors. These quality components smooth voltages and reduce high-frequency noise, so your GPUs get the good-quality power delivery needed for reliable operation.

PCIe Slot State Detection
B250 Mining Expert has built-in smarts to show the status of each and every graphics card from the moment you power up. The moment the Power-On, Self-Test (POST) screen appears, you'll see a graphical representation of the status of every slot — so you'll know instantly if there's a problem or whether your mining operation is good to go.
