  • Our take on the MSI X299 SLI Plus

    The MSI X299 SLI Plus is an ATX motherboard for Intel's LGA 2066 socket, built around the X299 chipset for Core X-series processors. It stands out with four PCIe x16 slots for multi-GPU setups, eight DDR4 memory slots supporting up to 128GB, and dual M.2 slots plus U.2 connectivity. It lacks built-in Wi-Fi and Bluetooth, so you'll need to add a card for wireless. Reviewers and owners praise its solid build and expansion options but note the dated platform and limited USB connectivity.
