I assume its possible to custom wire 4 wire molex and sata power connectors in the same set of wires... correct?

post #1 of 8
Thread Starter 
My SSD/ODD hot swap requires molex and my HDD hot swaps require sata power. I want to run all of it off of one connection to the PSU. I assume that's possible correct? I'm sure I've seen premade wiring that included both types on the same run.

What is the correct way to wire them? Thanks

For the pros out there: correct me if I'm wrong.
I think it is possible. Your molex needs 1 red, 1 yellow and 2 black wires. The red wire is is 5v, the yellow wire is 12v and the black wire is a grounding wire. A SATA power cable only needs an additional orange wire (can also be grey) which has 3.3v. So, I assume it is possible to do is IF you put your SATA connector first in line and stop your orange 3.3v in your last SATA connector you want to use.
Does this make any sense?

Liradon is right.

The molex goes 5V, GND, GND, 12V
The sata goes 3.3V, GND, 5V, GND, 12V

But what are you connecting it from?

I'll be using one of the connections for SATA/MOLEX on the PSU (one of the black 5pin connections on the top right of the PSU)

Yes, I get it, thanks!

You can generally leave out the 3.3v wire. The vast majority of modern drives don't need it. If fact if you look at the molex to SATA extensions that are available they also leave out the 3.3v as there isn't a feed from a molex connector.

The orange wire is only there for staggered spinup and hotswap if I recall, it's rarely even implemented\ on drives because of people using Molex->SATA adapters and first gen drives like yours used both Molex and SATA power connectors

This is a quote from Computerforum.com. Best to check if the drives you want to power need the extra 3.3V wire for things like hotswap and stuff. Depending on your conclusions, you can choose wheter you implement this 3.3V wire or not.

Spin up is on pin 11 which is a ground wire, not a 3.3V wire.

Pin 3 is the hotplug for 3.3V, but if the drives don't use it, then the hotplug doesn't need to deliver it.
