Please recommend an energy efficient VDSL2 modem

I did a little scouring on the net, reports of 30w on UPS's with no load. O_o, but also some reports with only a couple of watts, if I ever get round to it I will test both, but I do remember one of my UP's is labelled as a green UPS, which seems to be an indicator its overhead usage isnt crazy.

So I set up the Vigor 130, and I'm happy to report that the power consumption is only 4.0W! That is 2.5x lower than the BT Hub 2 in Bridge Mode. Terrific result, it will pay for itself in less than a year.

Something else that happened which I did not expect was that the Vigor 130 solved my bufferbloat problem. With the BT Hub 2 I was getting over 1000ms of upload latency when the upload was maxed, so I had to set up QoS/bandwidth limiting in my Asus router to deal with it. That worked well, but it meant I lost a bit of upload speed, and my router could not use HW acceleration. Without HW acceleration, the Asus AX86U can only do about 630 mbps and I'm getting gigabit fibre so that wasn't gonna work anyway.

But now with the Vigor 130 and without any QoS/bandwidth limiting in the router, I am only getting about 20-30ms latency on the upload when it's maxed, so that's much better! No need to limit my speeds and also with HW acceleration the router will use a bit less power too. Very happy with this.

I'm pretty sure this isn't a "governed" term, so it likely means absolutely nothing. Could be that they use recycled capacitors or something daft and doesn't equate to its actual usage.

I'd def drop the UPS on a plug and measure it from the wall - It'd be worth updating here with your findings.

Congrats :) Glad you've managed to achieve what you wanted^

Thanks! A couple of questions unrelated to power consumption since I am new to DSL, if anyone could comment, I'd appreciate it

I set the Vigor 130 to PPPoE passthrough mode rather than MPoA/Bridge Mode. I tried both and they appeared to perform identical. Is there any benefit to using one vs the other? The BT Hub 2 uses Bridge Mode I believe. I googled this but found a lot of conflicting information.

Also, the Vigor 130 has BT approved firmware and also "alternative" more generic firmware. I went with the BT, but wondering if the other version offers any benefits, if anyone knows.

And finally, more of an observation, but my SNR margin target (or as the modem reports it simply as "SNR") is 11 dB for both up and down. This seems high, but I am on the highest sync rate of 80/20, so I'm guessing that's why it's high, not because my line is noisy or anything...?

I'm also happy to report that I am on a Huawei cab, not ECI, and I have G.INP enabled on the downstream.

I mentioned it as someone on reddit tested two cyberpower's the one labelled green had 2W of idle usage and the one without used nearly 30W.

I will test from a plug at some point, but might not be soon due to how hard it is to access and also to then read the plug in a total blind spot.

What might be easier is just to power everything off on the UPS, and then toggle the plug switch whilst watching my octopus mini.

Was this just the unit plugged into the wall with no load? I've seen some units go into a "standby" like mode when there is no power draw, I would say this is pretty uncommon in UPS' though. (And if its plugged in, why would you have no load on it? feels very "fudge the efficiency numbers" to me)

Yeah he said was powered on but no load on the UPS.

Had to change battery in UPS, so killed two birds in one stone, got a TP110 between the UPS and the socket now collecting data, will post some info here later in week.
