Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an adjustable voltage power supply system, method and computer equipment. Background technique [0002] With the development of mobile network equipment represented by mobile phones and the popularization of Tianyan, monitoring and other equipment, the annual data volume has experienced explosive growth. For example, when purchasing on Tmall Double Eleven and purchasing a large number of 12306 train tickets, higher requirements are required for the performance of the device hard disk. [0003] There are various types of hard disks in the existing market, such as SAS / SATA hard disks, NVME hard disks, and M.2 / M.3 hard disks. Different hard disks have different performance parameters and different application scenarios. During server development, the server needs to support different types of hard drives because of compatibility with different requirements. [0004] Wh...
