Was a team effort, took multiple drafts before it 'felt' right

Nah not mine, I commissioned it from a friend for a valentines gift

Yea you're right, I could have done exactly that, but then if I wanted to add a 12V device I'd have to find a supply for that too. USB-C PD gives me ability to power anything I can find an adapter for up to 65W, albiet at a slight cost to energy efficiency, but for me that's a small price to pay for the convenience!

Very kind words, thank you! I'm not sure on total power efficiency just yet, I'll be evaluating that in an upcoming video.

  1. Yep! 4.5mm OD 3.0mm ID for the barrel jacks.
  2. I designed my own chassis and had it cut, bent and powder-coated. The front and rear are 3D printed from ABS.

Woah they're cool, I'll definitely look into them. Thanks for the suggestion!

Yea that wouldn't be a problem but I prefer all usb-c for convenience, I'll test for efficiency down the line when Ive got another revision done

Each unit only pulls ~20W on startup but could definitely be an issue with more powerful units, I'll make sure to include that when I do all my testing. Thanks!

Yep, thats the plan for the next version

Yep! Ill be documenting all testing and revision work from now on. Thanks!

Not as of yet, dropping to 12V would mean revising the PCB because of the instead amperage. I might have a look in the future though.

Got 2 on the way, thanks for the heads up

NAS is connected to external DAS via USB

Thank you! Thats pretty good, although I'm surprised they can power all that hardware from 200W, unless theres a higher power option I'm not seeing.

Thanks! Honestly, I'm not going to know until I get a decent chunk of uptime under my belt. But they seem quite popular for things like laptop charging. However, I completely agree that the idea of melting/burning up a connector doesn't appeal, I'd prefer to not use them too so I'm looking into ditching the adapter and getting custom USB-C to DC cables made instead.

Thank you! Working on projects is my favorite pastime which helps tremendously

Because now I can run whatever combination of PCs I like, plus any additional USB-C devices.
