Why is a audio power cable usually 125v 10amp when my headphone amp asks for 10amp 250v?

[Space Lynx]

so as you can see here from my asgard 2 headphone amp, it shows 10a 250v, but every single power cable in my house is showing 10a 125v... so why is this a thing? I just ordered a 10a 250v power cable... going to try it soon... but any thoughts before I do, bad idea good idea?

edit: also why does it say 703w? i know for a fact my asgard 2 probably uses no more than like 30?

That's the max tolerances for the connector, not the device. Do not run 250v into your Asgard 2, if it's made for 120V you will blow it up.

Granted, you probably don't even have a 250v outlet. That'd be weird, and these are just straight passing the AC, so you'd never have an issue either way.

well the cable says 110-250v, and the outlet i will be using is standard outlet, so i don't think its possible to give it that much juice, i would have to use an actual like socket meant for a dryer/washer to get that many volts...

but you are right... i think i will refuse delivery when the cable comes.

Nah, if you like the look of the cord it's fine to use. You'd need a 240/250v outlet to hurt something. Just wanted to make sure you knew.

yeah i will be using standard outlet nothing like that, I just find it strange why the asgard 2 even says this honestly. I think I will just use a regular 10a 125v power cable like I have in the past and return this other cable I got coming.

i find it confusing why they even make this cable though, because a 240/250 socket for like a washer/dryer is a different socket, this cable wouldn't even fit that socket... so I don't understand why they make regular 10am 250v cables for regular sockets... and also my asgard 2 says 10amp 250v... I just find it a bit confusing and bizarre.

Just watch out with some of the Chinese cables and they switch the pins some times.

It's because, as @R-T-B mentioned, it's just that generic black socket is rated for use up to 250v @ 10 Amps. It's the same socket that is in the 230v version sold by Schiit - it's also likely it's the same socket used in a computer power supply that does work with either voltage so it would make sense the socket itself would need to be multi voltage rated. A power cord would be supplied with the same connector at the Amp but with a plug that fits the Euro/UK/Australian outlet. (those are the choices that Schiit offers when you order a device from them. I have a whole bunch of Schiit.

*edit*
It's technically called a C14

Use whatever cable you desire. My EV ZLX12P self-powered PA speakers came with huge cables that were too short and inflexible so I went to some of the old flat cables and have never had any issues even doing outdoor shows. I love those flat cables, I'd use them on everything if I had enough of them.

Keep in mind that finished-product devices are often made with many common or standardized parts.
This standard is called IEC 60320, and that 'inlet' is called a IEC 60320 C14. The power cable itself will be terminated with a IEC 60320 C13 connector.


The IEC standard cords ('Kettle Cords') are used internationally. This particular inlet is rated for applications up to the maximum voltage of 250VAC RMS. (90V-240VAC encompasses practically every application, anywhere.)

If you tear apart some '250VAC' IEC-IEC power cables, and some NEMA-IEC '125VAC' power cables, you'll find them effectively identical (on average). More than once I've made 'no-no adapters' to use NEMA-IEC 125VAC cables to power universal input devices on US 60hz 240VAC.

If you do some reading on the IEC plug/receptacle standards, and the 'controversy' between the 'US' 125V 'spec' and 'Worldwide' 250VAC 'spec', you'll see why I don't fret mixing standards. (WIkipedia: IEC 60320)
Basically, any IEC cable safe enough to use on 125VAC will also be safe to use @ (up to) 250VAC; it's all in the insulation and wire gauge on the ampacity. (note: Don't assume the same interchangeability in receptacles. Some IEC receptacles have basic power filtering, etc. Really, only a concern if you're kit-bashing or part-scavenging for other projects.)

Regardless, never exceed the input voltage listed on the Regulatory/Product Information Label. The inlet here, is a worldwide-generic part.

Keeping things simple the american cable is better, since voltage is lower the wiring has to be thicker, if you get a cable for 230V mains then it'll be thinner and more flexible. It will still work tho.

I doubt the 703W is power related, could be a part number.

 

[Ferather]

How many watts is too much with headphones with high voltage? What are high end headphones in power consumption, 6-10 w?
I don't think its 703w, that's some speakers for headphones and permanent deafness I would imagine.

Its more like a computer PSU, supporting 110v/230v on input, but a variaty of specs on output.
I also really doubt headphones could ever use 250v, or even 125v.

Even a USB wall charger will have to accept mains in (110v/230v), but then output USB specs in volts amps.

i already figured this out, basically it says that so that the user knows they can take it to europe and just buy a different cable and be fine

i was just a numpty.

First of all: thicker != better. What conductive material is used, is it a solid core or multi core? What kind of insulation and shielding is used? These all impact both flexibility and max amperage for a given thickness.

Lower voltage require thicker cables to achieve the same wattage. A 10A part is 10A regardless of voltage. But if you want to achieve the 2500W max rating of a 10A 250V cable using 125V, you need to use 20A parts.

No. It does absolutely not mean that. The rating on the socket is ONLY the maximum tolerance for that physical part (so, not your amp), you have to look at the power supply specification on your product to see what it can actually receive without blowing up/a fuse. It is possible that your amp only have a 115V compatible power supply for example. And no matter what input voltage it accepts, I gurantee that it will not consume the 2500W that socket is rated for.

the power supply is inside the amp, no way for me to know. doesn't matter i am not going to europe with it anyway. its staying right here and its working fine with the 125v 10amp cable. listening to it now and for a few days now and all is well.

thread closed really.
