Connecting power to SATA units

AntCodd · 11 Aug 2011 at 14:18

I'm just connecting up the power cables on my new build, and I have some cables for my Lepa B750 PSU that have 3 SATA power supplies and one 4-pin molex supply on the same ribbon.

I was wondering if I can use a single ribbon to supply a HDD and optical drive, or should I use a separate cable for each drive?

You be fine

Cool, also, the PCI connectors seem to have 2 6+2 ends, one at the end of the cable and one coming straight back out of the first plug in the opposite direction. Does it matter which I use?

It should not matter, just double check it fits ok.

Edit: Just looked at the pics, the single end would plug into the PSU.

Cheers, they both seem identical. Just don't want to fry anything, you know

See my edit above

Yeah the single end goes in the PSU, but on the other end there are 2 6+2's

Looks like Lepa have used one cable which can supply 2 power supplies to the gpu rather than having 2 separate cables going to the gpu.

Some gpu's require 8 pin + 6 pin power, just leave the 2 pin to one side if they are not needed.

If that's the case should I use just one cable for both 6 pin sockets in my GPU?

usually they are two separate ones

AntCodd · 11 Aug 2011 at 14:53

So should I play it safe and use 2 cables instead of one double-ended one?

RJC · 11 Aug 2011 at 14:59

You will be fine using one cable to supply power to both ports.

Nice one. Thanks a lot for the help.
