I'm working on making an external hard drive enclosure. It will require 12v and 5v connections. I am thinking about using a 12v power supply along with a 5v step down. the parts I'm wanting to use are. https://www.amazon.com/dp/B08MCCSP38/?coliid=IGTEQDJ1Z8UYG&colid=2Y2WLETYUI3XK&psc=1&ref_=lv_ov_lig_dp_it Does this seem to be a reasonable plan and are these the right parts? |

That seems like it will work. there are also power supply's with both 12 and 5V outputs |

Garrett, Thank you for the response. I'll look around and see if i can find one with both, but if this will work I am happy. |

That looks like a switching power supply, which produces high frequency interference which CAN disturb your electronic. |

The working voltage of the hard disk is +12V and +5V, and the working current is 0.50A-0.80A, about 0.65A. +12V provides power to the spindle motor and seek motor of the hard disk. +5V provides power to the hard disk's circuit board. Power supplies with 12V and 5V output are no problem. You can also find more on https://www.newomi.com/search?keywords=Power%20Accessories Power Accessories |

You need step down DC-DC back converter, like car cigarette power converter to USB 5V. There are millions chips and solutions. On Aliexpress you can find a lot for less then 1$: MINI DC-DC STEP DOWN CONVERTER. Check what power HDD required on 5V rail. Usually it is less then 1A. |
