External Hard Drive Power Supply
 
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.

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

I've had a couple fail, and a couple more that haven't in years.

Fraid not. Tho the better brands from the US etc are more likely to survive.

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.

Not with an AT supply rather than ATX.

Yes, because everyone has rescued the old AT power supplies from their
386s and kept them for 20 years.

Is it time for your medication?

The design of most AT PSU's resulted in lack of regulation of the
12V supply unless there was a reasonable power draw on the 5V rail
too, much more than disks will draw. This was sometimes bad enough
to cause problems with the disks. The usual way around this was to
leave the old motherboard connected to the supply too, when reusing
an old AT system as a disk enclosure. Not efficient, but then AT
PSU's weren't as efficient as any modern PC PSUs anyway.

Much better would be to buy an external disk enclosure. Single ones
will usually have a 12V (or higher) wall wart, and a tiny switched
mode PSU in the enclosure to generate 12V and 5V for the disk.

+1.

That said my cheap Chinese USB to IDE/SATA has never given me problems
either.

which brings us back full circle to the problem the OP is trying to get away from.

It's the same old isn't it, wanting a good reliable psu but wanting to pay chinese prices. Maybe look at chucked out wallwarts to find good brand 12v & 5v ones.

No, really - I want to pay EU/US prices for a decent bit of kit.
Something as solid as a laptop psu, instead of a flimsy unbranded horror
off eBay.

Hacking two wallwarts together or converting another PSU will do the job
for reliability, but it's not exactly tidy or portable.

Ha! I kept a couple for years and years and eventually binned it as it
was taking up space and I'd never used it for anything.

I don't think mine even powered up the fan if there wasn't a decent load
either.
