Best linear power supply for Nucleus now?

IFI’s response to the request:

Hi Vad ,
We would recommend the new 15v iPower Elite for use with the Roon Nucleus. If you connect an External Nas drive it also will sound better with a quieter power supply .Be careful if connecting a external USB hard drive as they may take to much current from the Roon and make the power supply run hotter than normal .

Demand that they prove this before blowing 700 clams on two of these things (one for your NUC/leus, one for your NAS).

Until they do, refuse to give those people money.

Did Roon themselves ever bring out their Linear Power Supply? …its mentioned as being on its way in a number of reviews of the Nucleus, which is something I’m considering moving to from my Mac mini based solution. Maybe I missed an update on it.

No, I would assume because no one has been able to demonstrate any differences at output. Don’t forget that RoonLabs aren’t two-bit crooks…

Thats interesting. I’d have assumed that they recognised the stated benefits to start developing/sourcing one. Maybe it never got that far - but there was a release window spoken about - so it clearly got somewhere!

Seems like I misremembered things a bit - see this and that.

You didn’t misremember, you just read between the lines.

Cheap switching PS are notoriously noisy and that noise might find it’s way back into your audio components (preamp, amps, DAC etc) through your mains electrical lines. So depending on the design of your system’s components PSs, you might indirectly benefit from using a linear PS with your Nucleus.

I use SPS 500 (https://www.sotm-audio.com/sotmwp/english/)

but, in these days I prefer to use xiaomi 2000 battery with 45W PD output.

Hi @LarryMagoo

Just like you, I never turn it off, and yes, it does get warm. I will make sure the room stays cool enough during the summer. Eventually, I reduced the Matrix X-PDIF 2 voltage to 5, and the sound got richer.

I can highly recommend the HD PLEX 300W LPSU.

Serhan,

I’m glad you like it. I’m so impressed with it’s versatility and reliability! The SQ improvement is, of course a welcome benefit!

I posted in the main forum before finding this…so I figured I’d ask the question again. Can anyone confirm if the NEW model Nucleus (the one Roon advertises currently) is a 60 watt unit or a 90 watt unit? My dealer insists that it uses up to 90 watts, whereas previous Nucleus models used 60 watts. This would affect which LPS I would purchase. I’m considering the Keces P8 dual unit, but that would only be 4 amps or 80 watts. I would have to purchase the single zone P8 which provides more wattage…but doesn’t have the second zone.

The power use will much depend on if you also have an additional SSD internally mounted or also USB drives or a USB powered DAC attached to the NUC/Nucleus(+). All these adding add up to more DC power needed to supply them.

For sure the HDPlex offerings of the 200W/300W units allow for 10A at 19V / 12V which is well more than would be needed. I’m running a Lumin D1 and an EtherREGEN plus and i7-7700 with a 16TB HDD on one HDPlex 200W + a 12V cooling fan running at 7.5V for some air movement in the area. It’s been working fine for several years now.

I second the comments of the Wizard above……plus multiple outputs where two of them are adjustable!

The Uptone JS-2 LPS has just what you suggest. I’ve been using one supporting both a Nucleus and EtherREGEN for about 6 months. Perfect.

The Keces P8 dual power unit will work fine. I run my 90 watt NUC8i7BEH and my network switch off of mine. You will never need 90 watts. My NUC pulls 3.0 amps for a split second during startup. The rest of the time it runs at 0.4-0.7 amps depending on if I am upsampling or importing files.

Has anybody compared the SGC 12v Linear Power Supply VS iPower Elite by iFi Audio on Nucleus? They are similar in price just curious if much of a difference in performance.

Thanks

The Nucleus should be run on a 19V power supply rated at 65W. I think this rules out the iFi power supplies.
