Yeah, it's really terrible how people try to actually solve somebodies problem instead of answering a question blindlyNah, just a typical ASR crowd that doesn't read the thread title or the OP's specific queries. Happens all the time and it's funny to watch.

Build quality seems fine to me.
Yeah, let's see you handle some DutchSomebody's (not somebodies- that's plural) problem, was not even remotely a problem.
Of course he has something to solve, which becomes quite clear later on:He had nothing whatsoever needing to 'solve'. Don't you get that? Useless, superfluous and unrelated 'advice' is not advice, it's a waste of time.
If there is nothing to solve, there is nothing to ask.So I try (based on my professional mindset) to ensure (within reasonable cost limits) that my power delivery in the upstream components is as clean as possible in the off chance that some downstream components are affected (i.e. have poor power filtering, poor jitter rejection etc)
I beg to differ.Typical with ASR members. They just miss the entire point completely.![]()
So, it's by Chinese "Sengterbelle" cooperative.Looking to power my low end PC with this (it pulls 22w max).. any general thoughts on quality?

Do follow up with some noice performance testingI hear what you are all saying, that it doesnt matter but I cant let it go... so yes I am a schmuck, at least on this point.
I am of course aware that some no name LPS has doubtful quality (in terms of both build, longevity and performance), hence my post.
I am also aware that high priced LPS's are a rip off so was looking for the holy grail of good price/good performance.
So with some more digging, I found this puppy: https://www.fiio.com/pl50

I have a contact that will measure its noise performance for me.
Guilty as charged. I assumed things which I shouldn't have done.Nah, just a typical ASR crowd that doesn't read the thread title or the OP's specific queries. Happens all the time and it's funny to watch.
The OP wants a reliable power supply for his small computer. He asked for advice on build quality of the linear supply pictured and most of you start dribbling on about cheap Chinese ( orig Taiwanese) (Meanwell) SMPS supplies.
The simple facts are low cost SMPS supplies are unreliable when compared to a supply such as the one pictured. If you'd seen as many dead SMPSs as I have, you wouldn't have one anywhere near your HiFi. The only weak point as I see it with the pictured PSU, is the relatively poorly mounted, soldered power switch. It is not up to the standard of the rest of the PSU. I'd also want to be checking idle transformer losses/temps, as some Chinese transformers are pretty ordinary in that respect.
But overall, I'd rather have that supply running a small single voltage input PC than any SMPS you'd like to name. At least it will still be working in 30 years.
The waste of money comes in a few years when the cheap SMPS has overheated, dried out its caps and spewed its guts all over the non-ventilated plastic case it was jammed into. And, likely taken out a downstream component that couldn't deal with the extreme ripple in the 'DC' it was supposed to be outputting...
I've run large IT support departments with thousands of machines of all generations as well as data centres. This also involved negotiating long-term kit-support contracts (with real-time data about failures, spares, returns etc.). Based on this real-world experience, SMPS PSU failure across thousands of PCs is a non-problem. On average, the processor + OS + performance + storage etc. move to obsolescence years before the average PSU dies (especially amongst coders - i.e. the OP). Occasionally there are issues - e.g. where ONE generation of product or a batch of devices has much shorter life than expected (this can be more obvious in data centres where all of the "chassis" is always on and operating much closer to 100% load than a desktop PC).
I've also supported big studio facilities with lots of Linear Power Supplies. They fail. Possibly just as often as SMPS in computers.
One thing that does stand out from my experience - being a cheapskate is a big mistake. For my own personal use I would always spend several times more on a branded computer PSU than the cheapest no-name brands. I wouldn't spend less than 100 for a computer PSU because its performance is critical.

Its from a well known company and is typically used to power their desktop products so its doubtful that would develop a power product that would be detrimental to their own products.
At 12v/3A its all I need, shipping was free (but will take 3+ weeks to arrive) and was on special so I got it for $US 100.
I have a contact that will measure its noise performance for me.
What kinda gets lost on this forum, at times, is maintaining perspective: You all get your tits in a tangle over some cheap purchase as you are sticking to your principles but as has been stated many times,audio is a hobby and tinkering with stuff is a reasonable part of the deal.
If I was proposing to spend $500, $1000,$4000 on an LPS then sure, try and talk me down, but a hundred here or there....
Peter
But my question wasnt about if the LPS was suitable for my PC... just whether the build quality of the LPS was up to snuff.
I didnt create the rabbit hole.

At last, another member who listened to the OP, answered his questions and left his own agendas and BS at the door.
I will keep it ear marked. I don’t know what the Virgin Hub 3 draws but just didn’t fancy risking my iFi Power X or an any other damage at this point. I have looked into it but info is scarce at the moment and I don’t have any instruments to prove anything or anyone’s suggestion. Thanks.No router will draw over 2A @ 12V, unless this is a PoE router and you are using it to power other decives like cameras etc. Most routers will probably draw 1/10 of that.
If you are looking for an ultra low noise PSU, thas is one of the best PSUs I have found (with much better, discrete voltage regulator):
The router can not affect sound, regardless of its power supply. Ethernet and IP are non-synchronous protocols with error correction.I am using the 12v 3a 230v version for my Router here in the UK. Compared to the cheap switching power supply that Virgin supplies and an after market Amazon alternative the LPS does give assistance to the sound quality when streaming, a notable improvement. More refined sound, smoother, less harsh digital edge in the music.
Wrong again ASR, just plain wrong again. You are getting a strong reputation online for just being plain wrong.The router can not affect sound, regardless of its power supply. Ethernet and IP are non-synchronous protocols with error correction.
…via the the piece in the chain that the power supply is powering and the overall outcome at the end of the line. Don’t throw the baby out with the bath water!How do you listen to a power supply?
