24 pin ATX power connector (motherboard)

I am wanting to know if you sell the 24 pin ATX power connector that is like the one actually on the MoBo.

I’ve got a “spare” power supply and I am wanting to make it a general use powersupply.
So I need the connector to plug the power supply cable into.

I’m guess the MoBo one would be nice, but if there is a cable “extension” version, that may be viable.

(But the search engine doesn’t really do me any favours if I try searching for “24 pin ATX motherboard connector”.

After a bit of thought:
A cable may be nicer.
That saves me needing to make a PCB.
With a cable, I could use a terminal strip and connect outputs via the strip.

P.S.
Oh, while I’ve got you:
I’ve seen these USB-C boards you can buy that plug into a USB-C port and it allows you to get/have a lot of different output voltages via the USB-C protocol.

Do you have any of these too?

Hi Andrew!

We have this product which should be the connector: ATX Power Supply Connector - Right Angle | Buy in Australia | PRT-09498 | Sparkfun | Core Electronics

Unfortunately we dont have a breakout cable, but we used to have this: Benchtop Power Board Kit | Buy in Australia | KIT-09774 | Core Electronics
The design files are open source so should help create something

We most certainly do!

But we’re looking to source the PPS boards Great Scott recently posted about.

Keen to see what you make!

Hi Liam.

Thanks. But - ITMT - it has been decided that an extension cable would be better with this as the right angle connector would mean I have to then build a PCB to hold it.

With the extension cable … Oh, I already said it.

I’m doing this because I got the PSU for the right price and although I do have an old variable one it is … 20-30 years old, and though it works, I think this would be a nice little thing to build.

When I get it started (building, etc) I’ll get some of the boards you mentioned as I may need an adjustable supply for some things.

Update:

Oh… Ok. That board is the one that takes the USB-C power and gives you variable voltage outputs.

I will need the board/system at the PSU end of the cable to give that board to talk to and request the other voltages.

Do you (Core) have those kind of boards too?

Updated update:

Ok, more reading this end.

So that board:

That goes inside the power supply I am building.
Then if a USB-C device is connected, the other voltages are given.

Sorry… Head is not 100% on this. Lucky I am only doing reconnaissance just now.
It is just it looks like it is going to be fun trying to MOUNT it so it connected inside the unit allowing external things to be plugged into it.

Yep, you’ve got it Andrew. You select the output voltage and once the USB-C is connected, you will receive that voltage on the other side.

And that’s ok, Andrew, reconnaissance is sometimes the hardest part of planning a project.

How though do I “mount” this board so it is part of the box into which the power supply is going?

As said, it is small and I can’t really see any mounting screw holes.

Oh, and again, just checking.

The blue block is the INPUT and it gets/has only 5 volts (and ground) connected.

There are two mounting holes on the board via the USB-C port.

Each has a diameter of approximately 1.3mm (the calipers get finicky with mounting holes that small).

It’s also 44mm L vs 24mm W (which I might add into the webpage).

As for the blue box, no. The Blue Box is the output and has variable voltages, USB-C is the input and takes 5V. I admit, it’s really poor wording so I grabbed one off the shelf and picked up the multimetre to confirm.

(Not against you)

The holes are 1.3 mm diameter? Yikes that is small! The bolts would be weak. (Thinking aloud)

Looking at it again - the link - you may also want to add a plan view also.
Just to help understand where the holes are.

The holes are near the USB-C port - yes?

(Oh a funny you may like.)

Yes, the holes are near the USB-C port.

Thanks, just wanted to be sure.
