Colorful releases motherboard that can hold eight dual-slot graphics cards

Colorful releases motherboard that can hold eight dual-slot graphics cards

The mining craze is doing crazy things, try fitting this one in a chassis :) Of course these mobos do not end up in one, but Colorful is releasing the C.B250A-BTC PLUS V20 motherboard, with eight PCIe x16 slots.

The LGA1151 motherboard has a unique PCB size at 485 × 195mm and was fitted wioth the Intel B250 chipset. It has one x16 connection and then 7 mechanical x16 ones running x1 (total eight PCI-Express). There is a lot of spacing for graphics cards, ergo you can use dual-slot graphics cards. 

The main specifications:

  • Intel LGA1151 CPUs
  • HDMI port
  • SO-DIMM slot
  • support DDR4 2400/2133MHZ memory
  • PCIE3.0/USB2.0/SATA3.0/MSATA
  • onboard 1000M LAN chipset
  • 1*PCI Express 3.0x16 slot
  • 7*PCI Express x1 slots
  • diversity extension pattern

Disappointing. I wanted to run nine dual slot GPUs.

X1 connections? the bottleneck would be real.... does AMD cards run on x1? i know they do on x4... Nvidia don't go below 8x on their new cards if i remember correctly ( correct me if im wrong)

Would mining even work on x1? that is so pretty low bandwidth

The only reason you'd want a board layout like this is if each slot offered more bandwidth, and, so you don't have to build some weird chassis. But since they're all x1 slots, why not just use one of the competing boards that support more slots? Correct me if I'm wrong, but I don't think this would fit in any full-tower chassis (to my recollection, full towers can "only" fit 5x dual-slot GPUs). That being said, if you can't fit this in a standard ATX chassis, why not just go for a competing miner's board?

I find it interesting how this board seems to be compatible with server PSUs, but the amount of power connectors seems woefully overkill. Cut out half of them and you'd still have way more than you'd ever need. But what I don't understand is if this doesn't use ATX PSUs and won't fit in an ATX case, why not just have a slot to mount a server PSU, rather than this complicated mess?

This whole board seems like an utter design failure, and it didn't have to be.
