1U replacement power supply 'solution'

Some time ago a 1U server of mine died (the power supply gave up). I tried to get the power supply repaired but it wasn't possible therefore a workaround was needed as there are no drop in solutions that I could find so with a little research and some help from 'baltz' via the forum a solution was found and attached are a couple of photos of that solution.... is it elegant, I think so but I will leave others to judge :)

Solution is a picoPSU (picoPSU-160-XT, 160watt (200watt peak) , 12V input DC-DC ATX Power Supply) and an external power brick (156W) both ordered via Amazon, and is still working well after a couple of months on test, will it last as long as the original I don't know but I now have a working spare 1U server again rather than a 'door stop'.

I decided to drill the case and mount the connector on the back panel rather than remove the old AC connector and have a big hole with the cables poking through but the choice is yours.

Thanks for posting!

Personally, I would like to see someone 3D print an adapter to mount the DC jack in the location of the old AC inlet.

The Cosel is a few mm longer, but a mm or two shorter on the other two dimensions, so you should be okay. Of course, the mounting holes won't line-up.
