Power cords interchangeable?

by Sajomir / January 23, 2009 12:23 PM PST

My brother accidentally left most of his PC cables in his dorm room, including the power cables to his tower and his screen. My question concerns whether we can cannibalize some other computers for their power cords.
The monitor and the tower PSU both use cables that I believe are the 125V 10A (1250W) type, or are at least shaped the same. I'm 90% sure that we should be able to use any of these cables since my monitor, tower, and Playstation 3 all use these cables as well and seem to be interchangeable. I just don't want to tell him "let's do this" and hear a lovely popping noise when we hit the power.

Just in case, the monitor's power-related specs are

Should the 125V 10A cables work universally?

If you are asking

That the power cables that fit the socket on the Computer tower and monitor are interchangeable, then yes they are. If the cord will fit the power socket, then they are interchangeable or common generic fittings.

Well it was more of a question that we could pull power cables from our older computers lying around, but it seems he went ahead and tried that and everything's fine. Thanks for the reply Happy

Power cord gauge

I'm glad everything is working for you, I just want to add one thing. Make sure the computer cords are the same gauge, or close to it. If you are running a high powered psu, and the cord is from an old low powered psu, then the cord gauge may be to thin. If that is the case then if you draw a lot of power the cord will heat up and it will make your system work harder to get the power it needs (electricity always run better when it's cold, as a rule of thumb).

Generally yes

Power cords (used on most PCs, etc.) for 115V in the US are interchangeable as long as the current capacity (a function of length and wire gauge) is adequate for the product, then it'll work fine. There is (should be) a different wall connector on 230V power cords. Some power cables of either type are shielded. I like to use the shielded ones when available and when I'm near a mom & pop PC shop, I'll ask to go through their "recovered" parts bins in search of shielded ones to buy, so I'll be sure to have some on hand. All my equipment that uses the standard ones have shielded on them now whether they came with one or not.

Sure, but replacement cords are cheap
by john3347 / January 31, 2009 9:09 AM PST

You can use power cords from one power supply/computer on another. That can be just a very temporary fix because replacement power cords are inexpensive in the computer department of any "big box" store that had a computer department. They are also not prohibitively expensive.

Don't worry about it

I wouldn't worry too much about the wire gauge. Computers just don't draw that much current. Even the bigger power supplies today can be used with the smallest gauge UL approved universal power cables.

Power cords for PCs and other appliances are standardized. If it fits, it'll work.
