Fosi's New Linear Power Supply

[voodooless]

Yes that feature ! power 3 devices from one neat looking box instead of a rat nest of wall warts

That’s selling points enough for me , just skip the audiophile marketing. It’s actually a great idea but why stop at 3 ?

There probably no need for a test it will most likely work fine as long as you don’t have special need like precision measurements.

Here you go

That looks WAY cooler, and it's actually fully adjustable. Terrific!

Not something I'd want to put into my setup, but to each their own...

saving perfomance aside until I get one, my main issue is I could NOT find a decent looking 1box solution that handles three DC outputs in the range I need . That is
(1x 12-15v) +(1x12V) +(1x5V )

There are other solutions, you know? There's even at least one that doesn't force one to submit to questionably "audiophile" power supply schemes!
Best of all, it's from a company with impeccable engineering credentials, so you know it's got to be excellent.

Just the the sound of blood pumping in your ears is far louder than noise from modern kit.
Unless you are a vampire or zombie audiophile.

My Tinnitus means I've not heard 'just' the blood pumping in my ears for many a long year now (said Tinnitus came back in my forties). My wife's hearing acuity is alarming however (yes I know...), as she genuinely hears quiet clocks ticking and birds outside I can't hear at all unless close-up

No idea how these perform in practise, but some seemingly well assembled Chinese linear supplies in solid boxes could be got on the 'Bay for well under a hundred quid I remember...

If only the manufacturers of small devices could agree to a standard, like 24V DC, homes could have a second DC "grid", no "wall warts" needed any more.
Yes, I know, Utopia...

If only there was an EU standard for smol power consumer devices. Oh wait...

Yes there is, but, that doesn't "save" customers from the "wall warts", unless they can charge via their PCs USB ports.
24V (or even better) 48V DC would probably suffice for most small devices.

USB PD supports 20V (standard power range) and 48V (extended) already, both up to 5A.

If all smol power devices used that, you could just get a multiport USB PSU as they already exist, and done.

One can dream...

There are wall outlets looking like the normal ones these days, at least for charging, like this one:

I'm sure there will be more specialized options as well, I'm in the process of choosing outlets for a house and a new world has been opened, there's thousands of new stuff around apart of the (standard these days) various automation.

I though the topic was about existing modest desktop audio power schtuff. mia colpa.

...some electrical designers and DIYers can certainly think of future cool stuff outloud with their keyboard for sure...type away

$1700 for a McIntosh branded empty box. All it has is a glowing McIntosh logo, and an IR repeater. Unbelievable.

funny...but actually stupid post from someone talking of wasting a few hundred bucks ... you should talk your book.

your link is pushing 2000$.
thanks for your expertise comments though

Reading comprehension isn't your forte huh?

Check again who posted what, before being snarky next time. And it's not like way cheaper options don't exist.

Ok, let's get serious then.
You want really nice power supplies at good prices?

Here's, just use a translator for German:

SCMS-Copyprossesoren/Konverter

I'm sure they put it in nice cases too, see the price list:

Yup. Makes the titular Fosi linear P/S look like a pretty good deal, doesn't it?

that is a cool thought, and it has some features like current control. I actaully spend time looking into these lab/bench power supplies you said are options...

but ...

1. recall I paid 233$CAD=123 pounds (delivered to Canada). The one above sells on digikey canada for 330$CAD
2. the voltage control and ripple numbers are not as good as the claimed Fosi PSU20 (may not be material)
3. the one above is ugly (depends on eye of the beholder yes)
4. its 70% wider and 250% longer and doesn't align with the ZH3/ZA3/ifiZen desktop vibe I am going for
5. it has front connectors and a carrying handle that would look ass on a clean desktop.

I have no beef audio wise with the original supplied power, but once again, my goal is clean integrated look and trying to get rid of wires, wallwarts and powersupply chaos.

I checked prices and such, and its not competitive to me. I like the concept and options , but the amperages are all too low for my use case, and it looks more complicated to me.

so far I will stick with my PSU20 solution and save 2 power plugins.
It's indeed a niche lifestyle product to be and seems well suited for Fosi-folks.

Listening now...not expecting the earth to move ... but so far its as wonderful as expected!
