The latest hardware component to be affected by component shortage seems to be DDR5 memory which is virtually out of stock across all major retailers.

DDR5 memory is one of the biggest features of Intel's 12th Gen Alder Lake Desktop platform but many users who purchased the processor and motherboard are now sitting and waiting to get their hands on DDR5 memory kits. We were expecting DDR5 memory to be short for a while but the component crisis is worse than anticipated. It turns out, that the main component of DDR5 DIMMs, the PMIC (Power Management Integrated Circuit) faces severe shortage, as reported by 12chip.
