Identify cable help

ScReWeD · 16 Apr 2011 at 15:19

Hi,

Im looking for some help to identify the type of cable i need to power up my 2.5" ide hdd.

The computer is a thin client and seems to have a 2 pin connector that i may be able to power off.

Attached some pictures to help explain.

Cheers,
Greg

The 2nd pic is STD molex connector, using only 2 cores out the 4, just need to connect to normal psu molex.

I used something similar to power up my old laptop drives to a normal pc psu.

The smaller connector is a JST XH series 0.1" pitch 4 pin. You'll find these used quite a bit on loads of jumper wires. They are also used on graphics cards. They are easy to find online with the connector, with terminals and 4 flying leads.

If you look in the first picture i need some kind of 2 pin to molex converter as the power supply has no molex cables to plug into.

Ah I see, you might need try Have a search around Google.

Sorry I can't be of any more help.

What sort of 2 pin? What types of power cables do you have available? Oh I see the 2 pin header now. The Molex connector is using only the 5v side of the connector (I think) and it's possible that the fan header may also be 5v. Do you have a manual? Was there ever a fan attached? Do you have a multimeter?

I have no power cables available.

The machine is a thin client with in built psu, there are no power connectors available except that 2 pin connector.

In case you missed my edit read my post above.

I dont have a multimeter and there was no fan attached when i got the machine, also dont have a manual.

Ok what is the board? Maybe the info can be found.

If you go wiring up a 5v hard drive to a 12v supply things won't go well.

board is a TR5670 REV1.32

Can't find anything. Must be too old. I find it unlikely that the fan header would be anything other than 5v or 12v.

Grab a 12v PC fan and connect it to the header, the yellow sense wire should not be connected as it's not needed. If the fan spins at full whack it's 12v. If it judders or runs appreciably slowly it's more likely to be 5v.

5v is good. 12v is not good.

Your wiring is simple enough though. Grab an old PC fan, cut the wires some distance from the connector, strip and join to the same thing with a male molex connector's red and black wires.

If the header is 12v then you would need to change the voltage using a DC regulation circuit which will get a little more complicated than just stripping and joining a few wires.

Tealc,

Thanks for all the help.

I have now sorted it by making up a cable as you suggested and all is good, i will get a photo up once i have tided the cable up a bit.

Cheers,
Greg
