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.
