Does anyone use C14 (3 prong computer plugs)?

[m0b1liz3]

I bought the power module (below 1) and was thinking of using a 3 pin computer plug (with only 2 pins in use) instead of a barrel style connector. There are always extra 3 pin computer power cables lying around and I figure it is a good alternative.

Since the alternative you mention is a barrel connector, I'm assuming you are talking about using that IEC socket as the DC input to your amp, rather than the AC input to the PSU module.

I would not use a standard AC/mains input connector to for a low-voltage DC input. Sure, you may remember, but anyone else who sees it will naturally think it is for mains, which will at best, fry the amp, and at worst, start a fire.

I don't think you looked at the links. 1st one was for AC to DC board. I only mentioned barrel connector because I am avoiding it. And just considering the classic computer power socket because there are tons of those cables around the house.

Yes, lots of people use the IEC power connectors - popularly known as kettle connectors (over here at least).
Consider using a filtered connector - to stop noise getting into your house main from the switchmode supply or on other projects for stopping mains borne noise getting into your project.

Thanks russc,

I didn't know they were called kettle connectors. I did see a filtered version on ebay and was about to ask about that next. I get mains noise in some of my guitar amps so might get one of those.

I notice most of them are specific mains voltage rated but this one is 110-250v:

I read your post and checked you links before replying. Perhaps you should reread your post.

I could have assumed you meant something other than what you actually wrote, as others seem to have done, because what you wrote doesn't make any sense and is a horrible idea. If I did that, and you actually meant what you wrote, then I wouldn't have answered the question you had, and you might not know it.

I'm still not confident that either I or russc actually understand what you are asking. It's plausible that you are asking about using a computer cord and an IEC port to provide AC to the AC input of the adapter board, and directly wiring the DC output to your amp board. It's also plausible that you are, in fact, talking about something else.

If you want to be confident that we are answering the question you have, please provide more detail.

Sure I didn't mention in my OP that the amp board is placed after the ACDC board with kettle socket 1st. I didn't think it was that unclear.

C14 (kettle) socket to ACDC adapter board to amp.

Original question answered above by russc, who also suggested EMI filtered version. I am noticing the EMI filtered sockets can be as cheap as $7 but some are selling for $65. Are they that much better/different or is it classic ebay overcharging?

Why not use the 3rd earth wire as well?
Nothing wrong with grounding your stuff properly.

These sockets are pretty much a no-brainer nowadays, just standard.
