Despite a recent dip in the popularity of cryptocurrency mining, experts predict that it is about to see a resurgence, with the cost of GPUs heading into the stratosphere, and a whole slew of warm bodies entering the altcoin arena and trying their hand at a spot of digital mining. A cryptocurrency mining rig necessitates the use of multiple Graphics Processing Units (GPUs) and, if you intend to install more than a couple, you’ll have to invest in a motherboard that can handle that sort of hardware. Here are five motherboards ideal for maximising the GPU power in your new mining rig:Strictly speaking, the Asus ROG Strix Z270E is a gaming motherboard, rather than a specialised mining rig but, like many such devices, it is easily adaptable to cryptocurrency mining, which is convenient, since you may already have this board, or something very like it, hanging around. The Asus supports as many as seven graphics cards and is capable of supporting sixth generation Intel processors.The Biostar TB250-BTC Pro is a different beast, having been specifically constructed for use in altcoin mining. This means its applications are pretty much limited to your mining rig, but the Biostar is reasonably priced and can handle as many as six graphics cards.The Gigabyte GA-H110-D3A also supports six graphics cards. Unlike the Biostar, it is durable enough to run your mining hardware 24/7 without the risk of overheating.One for the hardcore miners: the ASRock H110 Pro BTC + motherboard is a bit on the expensive side but, with space for up to 13 graphics cards, you’re doubling the amount of processing power your rig can pump out with many of these other boards.Of course, if 13 isn’t enough for you, you can always try the Asus B250 MINING EXPERT with its whopping 19 graphic card support. Truly a monster of a mining rig.
