This is correct.

If I were to purchase with the bundled sbooster from the official distributor then I would consider that the sbooster is the “original power supply”.
Outside of what parameters? 19v/1.75a is a little over 33w. While the standard Nucleus One ships with a 60w power supply, measurements indicate that the maximum draw of the device peaks at about 21w leaving plenty of headroom for the sBooster to be comfortably within the parameters required to be fully functional.
Just in case @Neil_Small is still in any doubt.

@Robem , I haven’t ever posted “any doubt”, much less any opinion on this thread, ever.
Please stop following me around the Roon Community as well as social media posting false information and other garbage or I’ll have to block you. All I ask is you be civil and an adult.
Yeah, you might, and it would be understandable. Whether Roon Labs does so is a different question if you need warranty. After all, the Asian shop page says,
In this package, we are providing an additional 19V DC Linear power supply from SBooster
and one might argue that an additional one is not the original one.

To me, the original power supply is the one supplied in the box with the Nucleus One.

My Nucleus One has been running for about a week and uses between 17 watts and 23 watts! When indexing the music files it was a maximum of 31 watts.

Sure, there are many examples of manufacturers playing it very safe. So, correcting, outside of what Roon wants you to do, and if they are the ones honoring your warranty - but, well,
YOU DO YOU! 
It’s your Nucleus - hope that it always works and that is not the $4K one! Would hate to have my warranty voided on that one.
That’s said, I wasn’t really talking to you or anyone advocating for the PS - was more like being amazed at what a supposedly official distributor is doing, as a general point in the discussion. I think there is an agreement that an official distributor replacing provided parts without the knowledge of the mothership is, well, weird.

Especially when the purpose of the replacement is “enhanced performance”, which goes against the mothership’s position on the function of a Nucleus, i.e. an appliance-like computer running Roon server, with no bearing on sound quality.

So, is there any really backed good reason left why someone should replace the already built-in and working PS of e.g. a nuclues PC? Considering all discussed points, technical and non technical.
Add a 4k display to HDMI, and you’ll see a further increase.
Taking an older Intel NUC10i7FNx, approved for ROCK, idle is around 5 W. Yet, under load the power consumption can rocket up to 90 W albeit this can only be sustained, with the supplied 60 W SMPS of ~90% efficiency, for short bursts*. Imagine how a 60 W LPS will perform with an efficiency of ~50%.
So, with the Nucleus One, we may think a smaller PSU is okay. Yes, there’s lower TDP (potentially allowing passive cooling), but maximum frequency TDP is around 25 W. Add your peripherals, GPU, SSD, and memory, and it’s going to peak higher, especially with a display via HDMI.
So, there’s is good reason that Asus / Intel specify a 60 W PSU. Whilst Roon OS may not be as demanding, the power supply needs to be rated for the PC’s potential performance. It’s no different than booting your car with sub-optimal tyres. You don’t–or shoudn’t–do it.
A ~30 W LPS isn’t going to deliver anywhere close to 30W sustained power.

Well, there are a bunch of us that say no. And IMHO… it’s not an opinion. There is the audiophile version where everything matters (no matter how unrelated! ) and I posted my own version of being in the middle:
Logically, the network should isolate you from any consequences. If you believe in that kind of thing, I would say use it only if you have your DAC connected to the Nucleus directly, and of course, don’t fear warranty annulment.
Beyond that is a can of worms, IMHO and still suffering the consequences of getting into discussions once they get to that level.
Because I have a lps including emi-filter laying around that I set to 19v/2,3 A), I can give you my subjective experience. I don’t have measurement equipment and also didn’t perform a double blind test because I don’t have the facilities for that.
So for the Ones (and Titans 
) that are still interested: my opinion is that Roon picked a good smps for the Nucleus One that doesn’t really need to be replaced.
The lps seems more bass-heavy and detailed at first and more tame and relaxed but also closed in after some listening, but the experienced differences are too small to be sure of and might also solely be caused by the emi-filter on the lps. The smps might put out some more noise to the mains into the amp.
The Nucleus One is only the core in my set up, so it “only” delivers and receives data to and from the Netgear switch.
To put things in perspective: switching from wall mart to lps on my Chord 2Qute made a huge difference to me, the opposite of what you might read from Rob Watts or ASR.
Best of both worlds might be the smps with the emi-filter.
One other thing. The smps probably has the “-“ connected to earth, like the bigger iPower Elite, could that be a regulations thing for larger psu’s? That causes some groundplane noise. Not audible at the listeners position, but my powered subs don’t automatically switch off because of that.
So I might not use the earth pin when I will connect it to an emi-filter.

I understand.
Just to clarify… the statement above… does it mean “the linear power supply seems more bass-heavy”?
No, I don’t think that is possible because what the Nucleus is doing is only processing data, it doesn’t know of there is bass or not inside . It was the thing that came up when I listened to the same tracks after the change: more bass. It’s very subjective and doesn’t make sense since it is not an amplifier with a different psu. It could only be the noise that the psu’s are producing that is different so have different impact in the other equipment that is connected.
I noticed that the smps puts some dirt on the groundplane that the lps is not doing (because I disn’t connect the “-“ to the earth pin on that one). That might have some impact somewhere but that seems very difficult to find out exactly. Because my powered subs don’t switch off automatically when no signal, I suppose there is a lower frequency component in the noise too. The noise sounds like a digital product and stops a few seconds after a song has ended, so is probably made because of a Roon activity.
I wonder why the “-“ is connected to earth. Most lps’s don’t do that. Since my amps have just rca-connectors and my main amp has the ground connected to earth, I occasionally suffer from other to earth connected equipment. I will probably put an 8Ohm // 0,47uF between mains earth pin and the earth pin of the smps and build the whole stuff in a metal case.

Yes I use one of these between my streamer and DAC with not subtle improvements.
Simple, low cost solution to clean up USB without spending ridiculous sums. I tried the HS02 between PC and DAC and, while an improvement, it still sounded better with the streamer in the chain.

So, you could take a DAC that costs say $100, put it in the same box with this device, call it an isolated DAC and sell it for less than $199, since you don’t need some of the extra parts and separate marketing. Seems like quite the ommision on the part of engineers.
Yes but parts pricing is usually multiplied X5 so it would end up costing more making the product harder to sell.
So the parts for the HS02 cost probably around $20?

Yes I think that’s the way electronics work then you have development marketing and other overheads along with profit to add on.
