I bought 6 of the anker branded usb hubs for running asicminer usb devices. They've worked okay, except so far a shocking 3! of them have had failed power supplies. The first I RMA'd the whole hub, got a new one working great, but for the second failure I noticed it was just the power supply so I told anker as much, and they just sent me an extra power supply.
Well, now that extra ended up being DOA and another hub's power supply has failed in the meantime. I understand anker support is supposed to be good, and I'm sure they will try and send me more replacements, but the downtime and waiting is rather annoying. I'm thinking about just buying a 12v 5a power supply and seeing if it lasts a bit longer than the 4 amp supplies anker ships the hubs with.
Any recommendations? Anyone else have problems with anker usb hub power supplies?

I don't have a power supply recommendation, but they probably failed because of improper cooling. I also own a few Anker 10 port hubs and the power supplies gets frighteningly hot. They just weren't made for 24/7 full power capacity (PSU rated for 4A -- 10 block erupters x .5A = 5A).
Get a fan for the power supplies you have left before they fail. I use a coolermaster laptop pad and haven't yet had any failures.

Thanks for the suggestion, I too noticed the power supplies run hot. I found an old 12v 3a power supply that came with an lcd monitor and tried that, and it works fine. Just to play it safe I only have 7 devices in that hub, but it's been working overnight and all is good, and the power supply is actually running a bit cooler than the default supplies anker ships. I've also contacted anker so hopefully I can get some new working power supplies. I noticed the original 10 port hub have 12v 4a power supply, while the newer model has a 12v 5a supply, maybe that extra amp makes a difference. I'm tempted to just order a couple of power supplies from amazon such as this- http://www.amazon.com/Adapter-Power-Supply-LCD-Monitor/dp/B003TUMDWG/ref=sr_1_1?ie=UTF8&qid=1376391898&sr=8-1&keywords=12v+6abut I'll wait and see how the next replacements from Anker do. |

I have some 10 port Anker hubs I'd sell for .5 BTC shipped (in the US) if anyone wants them. International shipping will cost extra.
I haven't had any issues with mine.

Has anyone torn down one of these hubs? I was hoping that as they use 12v PSUs, they might have a proper DC-DC converter inside, rather than a linear regulator which would just burn power to turn that 12v to 5v for USB... I'm thinking of running multiple USB hubs with 12v inputs from a 100/150W enclosed PSU like this: http://www.rapidonline.com/Electrical-Power/Mean-Well-150W-Chassis-PSU-12V-85-2265 |

Why don't you just hook up the hubs to a standard reliable ATX power supply? A small one would be able to handle all your Anker hubs. All you would need is an adapter.

Tired of substandard power distribution in your ASIC setup??? Chris' Custom Cablez will get you sorted out right! No job too hard so PM me for a quote

An ATX PSU would probably be cheaper, but a 12V only supply that is designed to be run 24/7 and is smaller and fanless, might actually be a better spend - for me at least. |

I tore down my ORICO p10 hub, which seems to be an Anker clone, and it did indeed have DC-DC converter chips and inductors, so I expect it's fairly efficient  My power meter is reading 32W at the wall for 10 USB hashers & the original laptop style PSU - so the loss is only about 7W. |

Hi Gingernuts and or anybody else who may know, My apologies if this is slightly off topic but I have myself just purchased (rightly or wrongly) an Orico P10 hub (P10-U2-BK) and was wondering would I be safe to use a 4.5/5A charger to power it? 3A is sufficient for 5 ASIC's but not for 8! Of course this item is brand new so I'm a little reluctant to tamper with it but equally if it's good for the job then it saves me RMA'ing the Orico and trying to find an alternative. If you could PM me with a reply and thus not needing to continue to deviate off topic! Failing that suggestions on a 10 port hub for use with my Raspberry Pi (which doesn't work USB 3.0 devices) EDIT : Rec'd the expected "No" from Orico regarding upping the PSU on the hub.. OK time to RMA it and get myself two D-Link 7 port hubs.. A little upset I couldnt find the holy grail! |
