Buying a motherboard? Check this amazing site first

A board might advertise five M.2 slots and a stack of PCIe slots, which sounds great… until you find out that using one of them can slow down or disable another. The visual layout is a much easier way to spot potential conflicts than digging through a 100-page motherboard manual looking for one tiny footnote.

The useful part

A board might advertise five M.2 slots and a stack of PCIe slots, which sounds great… until you find out that using one of them can slow down or disable another. The visual layout is a much easier way to spot potential conflicts than digging through a 100-page motherboard manual looking for one tiny footnote. One of my coworkers here at PCWorld introduced me to this site and I plan to use it before I install any new boards on a build.

How it works

  • You can filter boards by brand, chipset, form factor, PCIe generation, number of M.2 slots, USB4 support, and whether they share lanes with the GPU.
  • MoboMaps is especially useful if you're planning to install a lot of hardware.
  • MoboMaps has a handy performance checker that lets you toggle different components and see which ones might end up sharing bandwidth.
  • MoboMaps currently covers more than 200 motherboards including the most popular brands.
  • If you're putting together a gaming PC or adding another SSD, MoboMaps is a great tool to check before making a purchase or starting a new build.</p...
