Alternative power supply

Eno2 — Sat, 29 Nov 2025 19:10:54 GMT

as an audiophile I use alternative power supplies whenever I can to clean the electrical signs that can be heard with my system. I have moved from BT to Sky full fibre 900mb. When I first discussed the move over I checked what the power connection was barrell or usb. I was told tht on the Sky max hub it was usb. That would be perfect as my Ifi elite pwer supply has an adapter that would fit.

the hub arrived today Model no SR213A. I have found that is a barrel connector 4.75 by 1.5 I can't find anything adapter to fit.

Do Sky have a USB model or hs nyone come across a adapter to fit.

Has anyone else come across this problem before?

any help would be very much appreciated

The 213A is a revised Max Hub model without a USB power connection. The original 213 released in 2023 has both that and the barrel connection.

@Eno2 Are you sure that you cannot find an adapter cable on Amazon, plenty barrel connectors on there not sure what you bave on the PSU that you are using, you may also find that the USB connection is NOT a straight 5VD.C. but higher and through a special sky PSU Unit, do not have one so cannot say, but would be surprised if it was not a 12VD.C. PSU adapter! May be someone reading will take a look at a Max USB style PSU and say what is on it!

Question did you also post a few weeks ago about something PSU wise for the Audio/Hub?

@Eno2 4.8mm x 1.70mm is the standard and it will be fine!

I may have to send it back and cancel the switch. I believe that power supplies make a major difference in cutting electrical interference in components. I lived with BT and the ifi power supply for sometime and extremely happy with the results. The main reason I moved over is that BT or now EE and I not that happy with the service.

I have tried some of the connectors I have and it's one of the smallest inner pins around. A standard barrel adapter will not fit. Thanks for your reply.
