[SOLVED] How best to connect 12v mini monitor to desktop pc sharing laptop style power cord

[natcha12]

Hi all,

Bit of conundrum here. I'm a bit handy craft-wise but electrical isn't my forte.

I've a 12v 120w Pico PSU (not knock off, the real deal) and adapter on the way, and a power save optimised G4400 ATX build. How would i go about attaching a small monitor to the same power adapter?

1. Use a DC splitter, possibly with an extension ~10cm to reach the monitor
2. Take a (fused?) 12v line directly from the PSU/mobo

The adapter I have coming should give full 10amp, with probably 80-90% efficiency so 100w+, PC on Furmark GPU and CPU simultaneous burn in shows under 50w, and monitor should be only 5-20w so its easily within the limits even with a SSD or so.

Any help appreciated. My attempt at a briefcase desktop PC with foldout keyboard tray and usable PCIe expansion slots must succeed!

You are using this power supply for the PC too? or just the monitor.

The monitor is 12V powered?

I would like to share the PSU and/or AC-DC adapter if at all possible between monitor and pc.

Yes. I am only researching 12v monitors as they would seem to be the easiest to implement, unless USB would work/have high enough power?

USB is 5V....so no.

You can use a splitter.

I'm seeing 70 watts max plus an SSD correct?

there were some USB double/y cable monitors i saw, and i have spare internal headers which i could put them on so that is still an option was what i meant.

70+ssd or 2, yes. I know it might need a thick ass cable, but im sure theres a splitter out there somewhere that'll do

16-18 gauge should work.
as far as a fuse...it's only going to save the PSU if it's not short circuit protected....but I think it probably is...so the fuse is probably not necessary.

Niiiice!
Seems £5-10 will do: https://www.ebay.co.uk/itm/18Awg-Ga...1a:m:mtfumaLiSF9fbJdUtfnRvEg&var=471115507171

I have 2.1-2.5mm plug adaptors handy too if they're needed, some sellers aren't too open about their sizes

Thanks bud
