Even the best motherboards often present connectivity and expansion challenges, particularly in compact form factors. A new PCIe AIC (Add-In Card) is an effective solution. There's an open-source project titled “AMD B650 Southbridge Expansion Card,” hosted on OSHWHub, that provides an interesting option to enable substantial expansion of your motherboard’s storage capabilities.
It is not the first time a manufacturer has developed an AIC based on an AMD chipset. Previously, ASRock introduced the “X670 Xpansion Kit,” a specialized expansion card designed for its B650 LiveMixer motherboard. This add-in card, which also uses the B650 chipset, elevates the B650 LiveMixer to the feature set of an X670-class motherboard.
