I will do my best, but what happens if they won't or say that they haven't got any...refuse the modem swap? This is why I am trying to find with 110% certainty what is supposed to be supplied as in what BT OR has contracted for.

At the end of the day, does it *really* matter. I never got given the new power supply last Thursday when I got the modem replaced and had I read this thread earlier I might well have asked. The one I had before is still working fine and if it fails at some point in the future then BT will provide a new one at that time.

Please consider the power rating of the old versus the new PSUs --

Old: 12V @ 0.7A (8.4W max)
New: 12V @ 1A (12W max)

Now look at the label on the underside of the 3B modem. What do you see? Something like --

MODEL: EchoLife HG612
NAME: FTTC VDSL NTE
POWER RATING == 12V, 1A

I've emailed Kelly and asked them for a replacement PSU - let's see what happens.

However I am a software man, know very little about hardware. What is the end result of using the older PSU going to be, other than using less watts

Is it possible to use a different modem than the one Bt openreach supplies? I know someone who is looking at FTTC, and have seen a Billion VDSl all in one for a pretty good price and would prefer to use that than BT open reach Huawei as they don't trust Huawei ( don't blame them to be honest)

Really no problem. Let Openreach come and install their kit. After they have gone, use the 'all in one' stuff. Obviously keeping the Openreach modem, so if there is a problem, you can try that instead.

It is not a matter of using less watts. The device draws the power/current the PSU does not push it. If the modem needs 1A and the PSU cannot supply it, the modem will not work correctly. Imagine trying to run your TV on a 160v mains when it is rated for 230v.

Before I get flamed, the above is simplified

Just sent him a text to say that it should be ok. Knowing very little about FTTC, will the modem need a username and password like ADSL modems/routers?

Thanks

You would be running the PSU at its design limits, thus may run hotter than usual, be prone to early life failure. It is feasible that the lower rated power supply may be more of a fire risk when running mismatched.

For the modem the result may be that you get memory errors, CPU crashes. Things may be okay under profile 8c, but with 17a using more power the PSU may slow some people down.
