ASUS B250 MINING EXPERT: Cryptocurrency Mining w/ 191 PCIe Slots!

feature

The World's First 19-Slot1 Mining Motherboard!feature

Designed to Max Out Your Megahash Rates!
ASUS B250 Mining Expert is the world's first mining motherboard to feature 191 PCI Express® (PCIe®) slots. With 18x PCIe x1 slots and 1x PCIe x16 slot on board, plus three zoned ATX12V power connectors, the B250 Mining Expert lets you run up to 19* NVIDIA or AMD GPUs in parallel to max out your megahash rates!
* Initially, the B250 Mining Expert Motherboard supports up to 8x NVIDIA or AMD GPUs. An unlimited number of GPUs will be supported following a driver update; expected from ASUS before 2018.

feature

  • 19x PCIe Slots maximize your mining connectivity and speed with up to 32GB DDR4-2400 RAM, USB 3.1 and Intel® Gigabit LAN ports
  • 3x ATX 12Vdc Power Delivery separates 19x PCIe slots into 3 groups, each with a dedicated 24-pin power connnector for reliable power performance
  • 5X Protection III Hardware-level safeguards with SafeSlot Core, LANGuard and Overvoltage Protection provide component longevity and reliability
  • PCIe Slot State Detection provides a real time indication of the status of each GPU
  • Individual Voltage Stabilization Caps provide steady voltage to your GPUs

Engineered to deliver the power your graphics cards need
B250 Mining Expert has been engineered to provide all the power your GPUs demand, cleanly and efficiently. The 191 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 keeping 24/7 cryptocurrency mining running smmothly unattended. That's why ASUS engineered B250 Mining Expert with 19 decoupling capacitors. These quality components smooth voltages and reduce high frequency noise, so your GPUs get the quality power delivery you want and they need for reliable operation.

PCIe Slot State Detection

feature

Easy management and debugging
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.

Mining Mode BIOS Optimization

feature

Simple setup
Unlike some rival boards, B250 Mining Expert has a special Mining Mode that's enabled by default, removing the hassle of having to make BIOS-level changes that are necessary to maximize mining performance. Mining Mode sets the PCI Express speed to PCIe 1.0 and disables the Compatibility Support Module, so you get the best stability and compatibility right out of the gate.

Best Network Performance

feature

Stay Online with Intel® Gigabit LAN and ASUS LANGuard Technologies
B250 Mining Expert is equipped with Intel® Gigabit Ethernet for the best throughput and lower CPU overhead, ensuring optimum performance from your mining rig. ASUS-exclusive LANGuard employs advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput; protecting the B250 Mining Expert from lightning strikes and static electricity.

More Profitable Mining

Money-saving Design
B250 Mining Expert boasts unrivaled cost-effectiveness. The ability to run up to 191 GPUs from one board eliminates the costly investment in additional CPUs, memory and drives that would be required to create equivalent mining resources using competitor motherboards; so you spend less to mine more.

Higher Hash Rates

feature

With so many slots available, B250 Mining Expert gives you the means to push for higher hash rates. With 16 slots occupied our laboratory tests generated results of up to 342MH/s; and up to 407MH/s with 191 GPUs in operation!

Lower TCO (Total Cost of Ownership)

feature

More hashes means more cryptocurrency creation, and that means more money from your mining operation. Compared to some 6-slot motherboards B250 Mining Expert delivers a TCO saving of up to $1.83* (US Dollars) per Megahash generation potential.
*Saving depends on precise cost of hardware and operating environment. Actual results vary.
