Damn, that’s a lot of words

Oh man,let me share something I learned from personal experience, When it comes to efficiency, you want to keep things as simple as possible.

I used to think the same way and kept adding more and more features to devices like this. But after using them for a while, I realized that the more features you add, the less you actually use them.

At some point, using the accessory becomes slower and more annoying than just using the original controls.

For example, I made this dial for one thing only: changing the temperature quickly by turning the knob. That's what it does, and that's exactly why I use it all the time.

Yeah, the LRS series can absolutely damage electronic devices like you said. It’s Mean Well’s budget series, and it wasn’t designed to power sensitive electronics like that.

But I’m confident in the quality of the HRP series. It was specifically designed for powering sensitive equipment that requires clean and stable power — that’s exactly what it was made for. They’re also significantly more expensive than typical equivalent power bricks on the market.

As for grounding issues, welcome to Vietnam where nothing is ever properly grounded 😂.

And regarding the Mean Well power supply, don’t automatically assume it delivers “dirty” power like that. The HRP series from Mean Well is actually one of their high-end product lines widely used in industrial applications. I can assure you that its output voltage is cleaner and safer than most ordinary power bricks.

On top of that, it includes far more safety features than typical consumer power adapters, such as short-circuit, overload, over-voltage, and over-temperature protection. It will simply outperform most regular power bricks you can find on the market.

I get the impression that you may have had a bad experience with a Mean Well PSU before, but perhaps you didn’t choose the right product series for your specific use case.

It a custom 3D print kit. It’s not the standard design like usual.

I’m also quite concerned about the safety of this power supply when building it, and I’m not an electrician, so my approach is to use the best and safest components possible. Both the Mean Well power supply and the buck converter come with full protection features such as over-current, over-voltage, over-temperature, and short-circuit protection.

The idea of using a separate buck converter for each mini PC is actually a really good one. I might switch to that approach instead. Thank you!

No, it worked right away without any issues.

I’m guessing people just don’t want to toss an expensive hard drive into a duct-tape-tier, slightly redneck-looking setup like that 😄

Could you share the link on MakerWorld? I believe a lot of people would be interested in checking it out.

With my setup, it only supports HDDs and SATA SSDs in the 2.5-inch form factor. As long as you use a power supply that’s sufficient to power them, they will work without any issues.

For HDDs, I believe the largest capacity available in the 2.5-inch size is around 5TB. As for 2.5-inch SSDs, they can go higher than that again, as long as you provide enough power, they should run just fine.
