Why would anyone buy this? Is it some kind of audiophile scam?
go away, audiophile.
yes, it's exactly that. some baboon on a forum found some psu used in hospitals etc. and think these are just perfect for audio cancer.
I'm absolutely no audiophile but isn't EMI a real problem for audio setups?
I've had cheap speakers that pick up all sorts of interference.
Also maybe it's not for audio but for other sensitive equipment?
Obviously in hospitals they want to make sure EMI don't mess up diagnostic tools.
>EMI
For audiofools it should only matter if it's in audible frequencies.
Hence why the old 2G phones interfered with your shitty PC speakers.
I've built some tube amps using chink switching dc-dc boosters instead of isolation transformers.
They are noisy but only bats can hear them, 50/60 cycle hum however, you can absolutely hear.
>isn't EMI a real problem for audio setups?
It can be, be the solution is already well known and standard in actual professional setups: balanced connections, such as XLR.
>the solution is already well known and standard in actual professional setups
I think the idea is to use this for non-audio equipment like a PC or something, not for the audio equipment itself.
To stop the PC (or other cheap, noisy equipment) from interfering with the high end audio equipment in the same room?
Absolutely not pointless It's a must for safety when working on electronics
Isolated/non-isolated and switch-mode/transformer are two separate characteristics. You can have a non-isolated PSU with a transformer, and a fully isolated switch-mode one.
That’s not a power supply. It’s an isolation transformer. It’s used to create a “floating” AC that’s not mains earth referenced. Generally speaking, the neutral of the mains wiring is connected to earth for safety. This isolation device essentially removes that, so that the AC output can be at any potential referenced to earth. It’s often used to eliminate ground loops, or to eliminate unwanted noise from being injected to mains from a particular noisy equipment and affect other devices. There are other uses, but that’s the gist of it. To put it in simpler terms, a power supply converts AC to DC. An isolation transformer converts 120v AC to again 120v AC, with the only benefit that there’s no electrical connection between input and output.
Wouldn't the computers on one side of the transformer induce a shitload of noise anyways? If the computer creates noise in the line it should be transmitted back through induction
It doesn't break down like the usual type of power source they make.
idk what the torus shape has to do with audio but as a transformer that's the best shape there is.
Sure, but it is also extremely inefficient. Linear regulators tend to have an efficiency below 50%, which is much lower than what any switching PSU could achieve.
Well don't regulate then and make the voltage with the transformer lmao
efficiency is for fricking gayotts
>Sure, but it is also extremely inefficient.
Search for "transformer efficiency".
After that search for a suicide method suitable for your intellectual capacity.
A transformer isn't the only thing required for a DC power supply
Depends for what, it has quite high interwinding capacitance, so it's not the best for high precision test equipment
switched mode power supplies are botnet, insecure, give you cancer, and reduce system stability
I want more cases where the motherboard is turned on it's side like Silverstone's Raven cases.
>I want more cases where the motherboard is turned on it's side like Silverstone's Raven cases.
> he doesn't know
What, that they have a patent for the design or something? Not sure how much I really believe it.
I think he's referring to the fact that some graphics card coolers don't work well in that orientation.
It's a pretty big drawback but it is something that can be overcome by picking the right card or using a water cooler.
Oh I'm not worried about that shit. I just like the idea of having the I/O on the top where it's most easily accessible for me. Instead I gotta just turn normal cases on their faces to enjoy that convenience
>some graphics card coolers don't work well in that orientation.
what the frick are you talking about
I would think something with a blower fan that pushes hot air to the bottom would be suboptimal. If it pulled in air from the case and blew it out the slots though, it'd be great.
I wouldn't use this case because there's nowhere to put a AIO water cooler though.
the whole "hot air rises inside of PC cases" meme needs to die. If you had zero fans and airflow, sure. but the moment you start pushing air around with fans it becomes a moot point
It was more about sucking in cool air and exhausting hot air right into the space where your card sits, then the fans just blow said hot air around until it rises out and gets sucked right back in.
You want your air going in one place and out the other.
the case has intakes at the bottom and exhaust at top. i am not seeing the issue
Some heat pipes don't work well vertically.
Heat pipes work by evaporating liquid at the (hot) GPU side and letting it condense at the (colder) fan side.
So if a fan sits below the GPU the liquid has to fight against gravity to return to the GPU.
With good wicking material inside the heat pipes this isn't an issue but some manufacturers cheap out on wicking because it only affect a tiny % of their customers.
so your IO shield and all ports points upwards?
why the frick would you want that?
A newer system than my current i5 2400 and GTX 750. Completely pointless, I know, and I probably won't, but I still can't help but lust over the prospect of buying Zen 4 this fall.
>no regulation
>no protection
>no inrush limitation
>shitty filtering
yeah no. maybe with a 12VO motherboard that never uses it for anything directly, but otherwise frick no.
i want cheap, old-fashioned ATX cases with drive bays, PCI slots and no glass
Why can't CPUs just work on 220VAC, imagine the power savings
>in the late 70's super high-end audio amplifiers were advertised as having the latest in transistor technology, featuring brand new switch-mode power supplies, flexible circuit boards and unbelievably efficient heatpipe coolers
>today audiophiles want a point-to-point wired tube amplifier with a transformer the size of a honeydew melon and it needs to run hot enough to fry an egg on it
what the frick happened
Boomers and their nostalgiagayging ruined everything.
Back then HI-FI appealed to normies who would have appreciated a smaller chassis and efficient cooling.
Audiophile gays however have nothing but superstition about modern technology, not all of them mind you but a good portion of them.
The loudness war. Since the mid 90s, inferior technology (vinyl) has often sounded better than superior technology (CDs, FLAC, transparent lossy formats). morons assumed this meant old was better, when really the new was deliberately sabotaged. From there it's an easy step to believe other inferior technology is actually superior, e.g. tubes vs transistors, class A vs class D.
switching regulators are the exact issue, you dumb moron
His point was that even if you get rid of the switch regulators in the PSU, you still have them in the motherboard, so you haven't gained anything.
thats fricking dumb. 1 layer of switching regulators is vastly better than 3 layers of switching regulators
No, you're dumb. Whatever ripple is on the previous rail will be completely irrelevant after another level of switching regulator.
has nothing to do with ripple, dumbass
Low ripple is literally the one, single, only and lone advantage that a linear regulator has over a switch regulator.
nope, youre a moron
Why are audiophools so gullible and don't take a day to learn about signal stuff and basic electronics?
>I want a linear ATX power supply with big toroidal transformer
You can't have a big transformer at such low voltages and current, all it would do is make a great antennae for noise and be hotter than a properly sized transformer
Imagine all the money audiophiles would save if they invested in a introductory signals course!
I want an actual good and working solar panel charger for phones
While we're on the topic, anyone know anything about these "zerosurge" or "surgex" surge suppressors? reviews/youtube seem to indicate they can protect against lightning strikes and can help isolate devices from each other. I saw a couple posts on forums stating they offer no protection against brownouts and slower transient surges though.
I live in an old house in Philadelphia, our wiring is shit, I get frequent brown outs and I've had equipment fried from lightning strikes before. Most of the house's wiring isn't even grounded.
I originally came across these while trying to resolve terrible RFI with my vinyl turntable. I've since swapped my Mani Schiit preamp for a Rolls VP29 and that cleaned it up drastically tho. I am still wondering if power conditioning would improve my sound at all, as even when my electric supply is good, kill-a-watt reads a constantly varying 118-124v, normally hovering around 124, and there's some audible interference when various appliances in the house turn on.
I would love to install new grounded wiring throughout the house and a standalone breaker for my turntable but that's not feasible at this time.
>they offer no protection against brownouts
What’s your question?
do they actually do anything or are they just snake oil?
more specifically:
1. are they effective as surge protectors?
2. can they actually work even when connected to an ungrounded outlet? (this claim seems particularly outlandish to me)
3. are each pair of outlets actually isolated from interference from each other/electric source?
A gf.
Multi-CPU motherboard for consumer chips, especially for lower end chips.
