Modem power supply question

Two questions really about replacing power supply to Xfinity Gateway Modem/Router -

1. Any benefit to replacing stock 12v/4.6a power supply with aftermarket such as ifi iPower SMPS? I have several external LPSUs throughout my system but wonder if wall to modem is worth an upgrade  (As I wrote this, I imagine the answer is “of course “.

2. Stock SMPS for Gateway modem/router is 12v/4.6a  ASAIK iFi and others only supply 12v/1.8 or 12v/2a   Would reduced output spec like this be ok?

Yes, I use an iFi X-Power with good results.

I've read opposing views of iFi SMPS.

Had an Aliexpress LPS for my modem/router which I've recently upgraded but yet to install.

Depends how close it is to your gear.  If it's across the home and on a different circuit, absolutely not.

Odd problem with iFi iPower Elite.  The barrel plug does not fit my XFINITY GATEWAY modem. None is my selection of adapters do either.  Does anyone know the barrel adapter size I would need to go from iPower Elite to the modem?
