Asus announces B250 Mining Expert motherboard with 19 PCIe slots and triple 24-pin power...

  1. We've touched on cryptocurrency mining in the past as well run some benchmarks, but one thing we haven't really covered is dedicated mining hardware. The most important part of any mining setup are the graphics cards since they perform the actual computations. With traditional hardware, you need a separate motherboard, CPU, hard drive, and RAM for every 4-6 graphics cards. This can get expensive and is really a waste of good hardware since mining with many GPUs doesn't come close to bottlenecking a modern system.

    But what if you could plug a bunch of graphics cards into the same motherboard and you only needed a single CPU to power all of them? That is the problem Asus' B250 Mining Expert motherboard is trying to solve. Rather than the standard 7 PCIe slots on a typical ATX motherboard, they have gone all out with nearly triple that number. The new board has support for up to nineteen (19) graphics cards on one motherboard. There is a single 16x slot and 18 additional 1x slots. Crazy stuff.

    In order to fit all of these, you'll need an open air case with rails to mount your graphics cards to. You'll also need a few dozen PCIe extension cables, preferably the USB variety, to connect your bounty of GPUs. To power this monster setup, the B250 Mining Expert comes with triple 24-pin ATX power connections as well as three additional Molex power inputs near the graphics cards.

    Other specs rounding up the B250 Mining Expert include an LGA1151 socket, two DDR4 slots, voltage stabilization capacitors at each PCIe slot, and a specially tuned BIOS for mining. For the time being, users will only be able to utilize up to 16 GPUs at once due to a driver limitation. For users that want the full 16 cards, they will need to use 8 from AMD and 8 from Nvidia. However AMD is scheduled to launch a new driver later this year that would allow all 19 GPUs.

    Well...this is just dandy. I mean, it wasn't like affordable gaming GPUS were already difficult to get ahold of or anything. I cannot wait for the crypto market to crash like the Hindenburg.

    This looks amazing. Why wasn't there something like this when I did my share of mining? :D

    They are making special GPU's to fit the board also which will actually make it easier to get ahold of gaming cards now...

    Uhhh, where is your source? Typically they use expansion cables and remote mount the GPUs "like the article stated". Now, they are making custom crypto cards now that have superior cooling, and fine tuned for mining, but once those are all bought out the graphics cards will go quick.

    What will really suck is if they make a Threadripper version with like 60 pci1x slots.

    I have 3 coin miners. What's amazing to me is how much of this equipment is gonna get dumped back ont he market come next year.

    1080's, 1080Ti's, and all other types of Video cards just dumped on Ebay.

    Eh wrong, the 1080 is particularly unpopular because it's memory sucks for mining. The 1080 Ti just isn't economical price wise. You'd be much better off getting RX 480s, 580s, or R9 390s.

    You're going to see 90% of these dumped mining cards be RX 480s, 580s, 390s, ect. Pretty much any high end AMD card. Nvidia only got a small taste of the mining craze because AMD cards were in such demand that the price eventually inflated to the point where certain Nvidia cards were viable, like the 1060, 980, ect.

    I'd buy this, along with the multiple graphics cards but I'm too cheap to splurge on any PSU that delivers more than 350W... and it has to be of obscure, Chinese branding.

    Are they not also releasing a mining specific gpu as well?

    Original article sources:,34879.html,34940.html

    Links to the products themselves:
    -- variant of their GTX 1060 6GB model (has no video output ports, so it's a pure cryptomining GPU)
    -- variant of their RX 470 4GB model (still has all of the openings for the video ports, but only the DVI-D output is still physically there)
    -- RX 470D 4GB is a special, China-exclusive version of their RX 470 (still has the DVI, HDMI, & DisplayPort outputs enabled), so not sure if it would be available outside of China

    Tom's Hardware had another story where EVGA was supposedly teasing their own cryptomining GTX 1060 variant (,34994.html). However, the product model indicated (06-PR-5161-RB)doesn't show up on their website (although a similar 06-PR-6161-KR does); based on the specs from the article, it looks like it's a mining version of their GTX 1060 6GB GAMING ACX 2.0 (single-fan) model (, with the video outputs either removed or disabled. But, it could just be vaporware, since it's not in their listed products.

    Why would a miner buy a gpu that has no resale value once the mining craze crashes?
    Unless the mining cards are significantly cheaper than gaming cards yet perform the same/better. I doubt that will be the case.

    Yep, those cards are all regular form factor. All that is different about them is that they are "more durable"

    It's basically a GPU with no IO options, kinda wasted silicon IMO. Given people will not want them, specifically for the lack of resale value. Unless you somehow manage to make use of SLI/Crossfire with them. I imagine those options still exist, but you lack the obvious connectors. Making them basically moot to most consumers in the end.

    How the hell would you cool 19 GFX cards?

    Need to be some crazy case that accommodates that board, also are there PSU that can power 19 cards or would these incorporate multiple PSU to power the cards?
