4pin atx to SATA?

[tolk]

I'm trying to put together a machine from a few spares/old parts. I have one of these power supplies with one 8 pin ATX power cable being used for the motherboard, and one male 4 pin ATX power cable.

Is it possible to power a SATA HDD and optical drive from the 4 pin? If so can someone point me at the necessary adaptor/s? I'm UK based so accessible recommendations would be preferred.

If you mean the standard molex 4-pin, then yes. Don't buy a cheap adapter, as they are known for catching fire.

This is for a single drive:

Here is a one for two, but they would have to be close by. Hopefully that gets you started in your search.

It's an 4 pin ATX power supply cable rather than molex, i.e. this: http://img.misco.eu/Resources/images/Modules/InformationBlocks/1210/SRH/SRH-1/197691-StarTech-com-8in-ATX12V-4-Pin-P4-CPU-Power-Extension-Cable-M-F-03.jpg

I don't know if i can adapt to molex first and then from that to SATA as you suggested.

You can't use that as it doesn't carry 5V, only 12V.

If that is the only available plug, your options are to get a splitter, or replace the power supply.

Splitters are dangerous because they make it easy to overload a power supply with too many devices. As long as you stick to low-power and keep the total consumption under the rating for the supply it is relatively safe.
