Help with power connections needed on DVD ROM

**Nygie** · 02-10-2008, 05:49 AM

Morning (in the UK anyhow).
I have purchased a DVD ROM slimline of course.
I bought it because it had a SATA bridge board on the back, only to find when I got it delivered that it does not have a standard PWR connector.
Please see picture

As you can see it is a 10mm wide 4 pin connector with pin 3 missing (going from L-R)
I would hazzard a guess at Ground, 3.3V and 5V but in what order?
If anyone can shed any light on this it would be a great help.
Thanks

Anyone?

Is that a floppy drive power connector? Try one and see if it fits. If it does, then look at color of the wires that line up to each pin and figure out whether it's 12V, 5V, or ground.

It is a floppy connector

Errr No it's not.
Pins just about line up but it is waay too big.... actuall wider than the connector on the board.
Nice try though, it what I thought it was until I tried it, how disappointed was I??

Easiest thing I can think of is to find out which model of dell it came out of and try to find info on the PSU's power connectors.

Or just grab a different adapter. This one is US$16. http://linitx.com/viewproduct.php?prodid=11678

It will take 5V, not 3.3.

I dunno man... it's dell proprietary junk it looks like to me. They're maybe something weird going on... Most all adapters I've seen for laptop parts are indeed just 5v, but all of my adapters have only 2 wires. 5v n ground.

True the drive only needs 5v n ground to funtion, but the adapter itself may require something else.
