1U power supply replacement (maybe)

Personally, I would recommend going larger on something like this so that you aren't near the maximum capacity and stressing the supply which could lead to early failure. I've found over the years with electronics that its better to have some reserve capacity vs operating near or at the max limits. That 10A power brick would only be able to deliver 120W and if the 160W PicoPSU ever needs more than 120W, like during the server starting up, then the power brick will be drawn over its limits.

As another alternative to a 10A power brick, here's a link to one that can deliver up to 20A (240W). With a power brick like this you shouldn't ever have to worry, even if the PicoPSU momentarily spikes to 160W or even higher, the brick will have a 50% reserve above the 160W max.

The only downside I see with this larger power brick are its physical dimensions look to be too large to fit inside the server. That may or may not be an issue depending on your goals around the server's appearance and extra wiring/cords.
Currently using the 20A power brick and have it inside server. No heat issues or power failures. 👍
 
Anybody know of any replacement power supply for a 1U that will work, doesn't need to be pretty and can be external with the cables fed through etc? Just would like to get an old 1U of mine working again.
Followed instructions from Mark, and I have a fully working 1U.
Thanks Mark !
 
Just to tidy the thread given I posted in another one a moment ago…

The Pico PSU solution is still rocking! :)

Aukuoy 24Pin PSU ATX 12V DC Input 160W Peak Output Switch ATX Pico PSU Mini ITX PC Power Supply for Computer https://amzn.eu/d/6PlJIIU

There’s a “new” power brick in UK available that works perfectly too, this one is 150w, whether that is overkill or not, I don’t know.

12V 12.5A Power Supply - COLM 12Volt 12.5Amp 150W Adapter Charger Connector 5.5x2.5mm DC Plug Replacement 12V 10A 120W for PICO BOX DC-ATX PSU HTPC Mini PC/LED strips https://amzn.eu/d/6dNyE2M

And then to tidy it all up, these fit perfectly where the power lead would have gone previously

Question for everyone: When your power supply bit the dust, did everything go dead? Or was it certain portions of the Server that died while some still appeared to almost work? Like did any drives still spin or did you still see a front status light or ethernet activity?
 
For me when it started to fail it would just stop and then when left some time it would restart but sometimes the drives lit but didn't always spin as perhaps there was not enough power available from the PSU.
I'm still using the solution I posted back some time ago and it remains working.

Thanks. I’m working on a client’s which has a lit power indicator but no drive or network activity. Quick voltage measurements show voltage at the motherboard and at some points on the ATX connector. I have similar replacement parts on the way so we will see if support was correct in diagnosing the problem as a power supply issue.
