The power supply standard for the enclosure complies with the 5V/900mA rated power specification for USB 3.x external devices. If an internal SSD exceeds this specification, it may cause compatibility issues with the host's power supply, leading to insufficient power. It is recommended to ensure that the selected internal SSD aligns with the power supply specifications of the enclosure. This precaution helps avoid situations where power requirements exceed what the host can provide, thus ensuring the smooth operation of the enclosure.
