Description
10 inch rack model for HP HSTNS-PL18 power supplies.
Designed specifically for the LabRax dimensions. If you want to make changes, you can modify with my 10 inch rack generator.
Note that this particular power supply has a variable speed fan. It is completely silent at low loads (less than a few hundred watts). It only makes noise when heat builds up. I've been running for months and have never heard it.

| 5v Buck Converter | https://amzn.to/4xiEp9L |

I've successfully tested this on multiple Intel Nuc and TPLink Switches and mini pcs which run at 19v and 12v . My intel Nuc happily run at 12v even though the original power adapters run at 19v.
The 5v buck converts are good for a few amps which is plenty for small switches / fans or other accessories. Please perform your own calculations to not overload the buck converter.
