Intel’s X299 platform is an appealing choice to consumers requiring high core count CPUs and plentiful system memory. Yet an X299 system build can get seriously expensive with the motherboard comprising a large share of that expense. MSI’s X299 SLI Plus motherboard proves that getting onto X299 needn’t be as expensive as you might think.
After a quick glance of MSI’s X299 SLI Plus you’d be forgiven for mistaking it with more high-end products in MSI’s X299 portfolio, like the X299 Gaming M7 ACK. Even on paper these motherboards are similar as the baseline for Intel’s X299 platform is so high in terms of default PCIe, USB, storage and general connectivity.
While the X299 SLI Plus is considerably more affordable than most X299 motherboards it still retains high-end features like dual M.2, multiple graphics card support, abundant USB, onboard power & reset buttons and much more.
It is a more fruitful endeavour to see what MSI has opted to leave out on the X299 SLI Plus, compared to the more pricey X299 Gaming M7 ACK, that helped it achieve its more competitive price.
As a high level summary MSI has thinned out the number of VRM phases and components, backed down to a single audio codec and ditched the onboard WiFi – all things that most consumers will happily be able to go without.
