External Hard Drive Power Supply

Oct 16, 2015 7 Replies

Hi -



Tenuously on-topic, but hopefully someone can help.



I use an external 5v/12v power supply to temporarily run hard drives during repair and tinkering. The Chinese rubbish they sell on eBay (eg



141793905523) has the quality & durability of a Kinder Egg toy. I've had about 5 of them now, they always fail.

I would happily pay £20 for a good quality version from a reliable manufacturer. Does anyone happen to know where something like this is available?



Thanks Steve


I just use one of these (ebay no. 151798079800) or rather, the same thing pulled out of an old PC before I threw it away.

Convert ATX PSU to Bench Supply

An ATX power supply? Small one won't cost much more than 20 quid. Get one from CPC - they sell decent quality.

Possibly unhelpful answer, but I use a PSU from an old computer for this. Obviously one has to be comfortable with wires around the place.

Heh, so everyone's suggesting hotwiring an old PSU. Funnily enough I had one of those, but I binned it because it was too big/noisy/tangle-of-cabley for easy portable use. Should've kept it and modified it, perhaps. De-soldered the un-needed connectors, done the 7v trick on the fan, could've been okay.

That'll learn me... :-)

Open it up and clip off the ones you don't need.

You will need to add a link to power it up, though.

Depending on what you are doing and what other PCs you use, how heavily loaded, etc., you could take a lead from an existing, working PC just for power.
