SATA to 12VDC Power for your headset

[Pimel]

So apparently SATA is capable of delivering quite some Watts and this guy created a cable set to draw power from your SATA port and interface it with your Vive headset (Maybe Pimax too?)

Eliminating the need for a power socket connection and making your cable management a bit better too.

According to him:
" SATA spec for 12V is 4.5A (54W) Vive consumes about 0.5A @ 12V (6W) "

[TrevorVR]

Awesome. Though why not take the 12V directly from the 12V rail of the PSU.
Edit. What is the Pimax 12V plug physical size in mm? Gotta do that mod.

[dillanski]

trouble is the headset will always be live unless you unplug it at the back , so it’s almost the same hassle

[Pimel]

You can unplug at the breakout box

[TrevorVR]

Or maybe someone could design a PCI card for the 12V output that would be on/off switchable with a software application, since Pimax DOESN’T HAVE A PROPER SLEEP MODE and using the on/off button is supposedly awkward and takes 25 seconds.

[dillanski]

That would be handy for turning everything on remotely , so less initial fogging when you want to use the headset

edit
But we can buy wifi plug (power socket) controllers already

[TrevorVR]

Looks like the SATA adapter is obsolete. Or alternative for this

No software control though

3.5mm
Anything which gives me 1 less plug is a win in my book.

[dillanski]

I just counted 13 plugs from where I’m sitting , mostly small adapters for 5v devices , your probably onto something there

[Virtualmisterl]

Yes I have 16 on 2 plug towers just behind my TV & I still have to run a 4 plug extension for adapters etc…
It got so messy I bought a small label printer to organise them all.

[dillanski]

And how many are just 5 or 12 volt supplies?

[Virtualmisterl]

5 12vdc adapters & 2 vive 5v chargers

[Virtualmisterl]

Right I just measured the vive 12v adapter & also tried it in the pimax & it doesn’t fit. It looks closer to 4mm

This would mean if you purchased this kit, you would need a different Male to Male 12v barrel adapter cable.
Even with the one from Amazon which @TrevorVR linked, we would need an adapter cable.
It seems Male to Male 12v in those sizes are hard to find, so would be easiest to solder a 3.5mm end on an existing one.

[Virtualmisterl]

I found this usb 5v to dc 12v voltage step up which would have been so simple but unfortunately it only outputs 0.6a

I’m not actually sure how many amps the pimax draws, so it’s possible it may work but the supplied adapter is 2.0 amps so doubtful.
When I’ve got time, I’ll try to get a meter inbetween to measure how many amps its drawing

[TrevorVR]

I’m trying to find an AC -> 12V/5V adapter with multiple outputs , but so far no luck.

[Virtualmisterl]

Yeah there seems to be a hole in the market at the moment for this sort of thing

[dillanski]

You’d need something like another PSU to supply lots of 12v and 5v units with a fan etc , 12v 2A = 24w times 10 = another fan

Here is what I’m using to power TPCast wifi adapter and antenna at once

So I’m sure it’s doable for Pimax no prob. Here I’m connecting to an unused sata power with a sata to molex adapter, then I bought the cheapest molex plug with cable and soldered it to a 5-2.1mm plug (most popular), which then goes to cctv power splitter, powering wifi, and for antenna I had to find a smaller plug so I used another adapter and some plug on cable I found elsewhere (didnt want to cut original cables). I’m only using 12V here but obviously you can use the other wires of molex for 5V as well.
