Computer Hard Drive Power Connector

[NogginBoink]

I'm thinking the best way to power all the goodies that I'd like to run next year would be from a spare ATX computer power supply.

Does anyone have a part number for the connector that would mate to the drive power connectors from the power supply? I think it would be a good idea to put this connector in future designs.

you just need a splitter.... i'll find one for you online...

Now I'm not saying this is the best price around. But this is what you want.

For a PCB mount I used Mouser: 538-15-24-4557
538-15-24-4745 is a little cheaper.

Thanks, Holt! That's exactly what I was looking for.

I'm going to put these on all the boards I design from here on out. It sure would be a convenient de facto standard to find this connector on any DIYC board that needed +5V.

Keep in mind that part takes up quite a bit of space on the board. Most boards will only need 2 of the pins. And not everyone will want to supply power to their board in that manner. I used the Y-cable that was listed above and cut one end off it. That gave me two power leads for 2 Ren64's. And they connected dirrectly to the PCB pads.

Just my thoughts

There was also some concern about the amount of force needed for inserting and removing connector, and the wear and tear on the boards.

I've been using Sata to 4pin molex adapters that come with new motherboards. Cut the Sata end off, use the red/black wires soldered to the board, minimum space on board.

Here's a pic of what I made to connect the +5Vdc. It's a standard 4 pin male molex to fit the available female Molex connectors in your PC.

Cool

Nice ideal

Great idea,
you can also bring out the +12 to power the Ren16 boards.

Just a note to be aware of though, :!:
Bringing these unfiltered wires out of your computers case could cause interference with radios or any radio based communications including WiFi,
TVs etc.
The cases are designed to keep the noise inside the case to not bother home electronics, and bringing them out and around the house could create some odd behavior of the radios.
This is of interest especially to hams, as they might be finding more interfering signals on their radios.

I'm going to try it, and maybe try to add some filtering to the lines to keep the hash inside the case.

So I'm once again looking that picture...

I don't like such circuits in high-current PSU output. At least put some fuses inline when you're going farther.

It bothers me a lot :( Especially when I saw local news about computer that catches fire. Can't tell more, but there was large hole in bottom part of front panel.
And then I thought, oh my... all those tiny fan wires... Nowadays a computer PSU has enough power to heat them up like resistance wire in heater. Maybe even to the point when they burn half.

Just remember, 20+A. Heck, mains circuits carry that much of current! And although PSU's feature overload and short circuit protection, what happens when there's no overload yet?
Scary things...

I was looking at this topic again and I plan to put an inline fuse between the banana plugs and the Grinch. I have also decided to tap the +12 for my FM Transmitter. Inline fuse there too!

Can somebody explain to me how the power supply is filtered inside the case vs non-filtered when it's outside the case? What do you do to filter the power if your using an ATX power supply harvested from another PC?

I'm with you. If its filtered in the case, it will be filtered out of the case. Our boards require filtered and the design of most of them (Grinch included) is to use the power from the PC.
