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. Nick |

Small one won't cost much more than 20 quid. Get one from CPC - they sell decent quality. -- *Bigamy is having one wife too many - monogamy is the same Dave Plowman London SW To e-mail, change noise into sound. |

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

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. -- *Everyone has a photographic memory.

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. 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. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

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

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. NT |

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. -- Scott Where are we going and why am I in this handbasket? |
