Hardware

In the NITRO+ X870EA PhantomLink Polar AM5 motherboard, Sapphire implements its implementation of the BTF standard for powering the graphics card via the motherboard and calls this technology PhantomLink. In our test, we examined the motherboard with a matching Radeon RX 9070 XT graphics card and tested the overall package. Sapphire does a lot of things right, but unfortunately doesn't get the full potential out of the concept.
