Powering LED screen from 12V on the picoPSU

Post by voidstar »

I've experimenting with a few 80W and 160W picoPSUs and a few LCD/LED screens, and they've all been reliably working like this.

The picoPSUs come with an extra cable, with a white connector on one end, and a SATA (and sometimes also Molex and other connectors, depending on where you order from). All $15 - $22 range. I've settled on an 80W 20-pin unit. I'm not sure if the "official" name is picoPSU or picoITX or picoATX ? These still have "patent pending" on them, so perhaps the industry just hasn't decided yet on any real standard.


With that SATA connector end, you get an adapter like this: (two different versions of the same thing, just basically different cable lengths)

SATA Connector to 12V DC Plug Power Adapter Cable (DC Plug 5.5MM x 2.1MM, O Series)

And can plug it into a smaller LCD/LED screen - like under 14" or so. I've gotten a few and so far all of them had a matching barrel size connector. And it's convenient that the screen powers up at the same time you power up the system.

I'm not yet sure if the Lazer3D is going to have a hole to tether thru and connect to the screen, may have to drill my own. But it's an option if you're ok with a smaller sized screen. Just I still haven't found an affordable flat screen with a white bezel. Beetronics has one, but I think it's widescreen and over $300 (and touchscreen, so the contrast ratio is only about 800:1).

I was also going to try one of those small projectors - but those all have a fan, I haven't yet found a "fan-less" projector. I thought a small projector going onto a silk or paper screen might be interested, but not with an audible fan going on.

Forgot photo for reference on the setup.

The LCD/LED panel powers up with the X16.

Also note the 4-wire Molex connector, it has both 12V and 5V also - I connect a USB 5v adapter on that to power things like IEC device emulator, WiModem, or slow phone charging.
