Yes, the 990 EVO Plus SSD is compatible with most desktop PCs, including those with HDDs (hard disk drives). The 990 EVO Plus uses the M.2 form factor and supports PCIe 4.0 x4 and PCIe 5.0 x2 interfaces. As long as your desktop has an available M.2 slot and supports these interfaces, you should be able to use the 990 EVO Plus SSD without any issues.
