Please look at the two 6 foot cords I am contemplating. I'm not an electrician. Which would replace my M4 2024 10 core iMac (A3137) power cord. I think the cord must be a IEC320 C5 to NEMA 5-15P 3 prong, (143W Power Adapter Extension Cable), whatever it's called. One cord is rated 1250 watts. I just don't understand volts and watts to start a fire or burn the iMac up. The original power cord is 3 meters long, just too short.

Either will do, even less expensive ones are fine.

The iMac is pulling 150W peak. That's like a bright floor lamp and those cords are much thinner than either of these.

JPack, what is the main difference in this third 6 ft cord. I don't understand why the Wattage and Voltage vary so much if any of them are ok for the one computer?

I don’t think the rated wattage is going to make much of a difference for less than 200 watts. If I had to pick between the two, the one on the right is UL listed and list the gauge of the wire. That gives me a little bit more confidence in the product.

The IEC 60320 C5 connector is used for many products from gaming notebooks to video projectors. Some of them can consumer a few hundred W.

The C5 connector guarantees at least 2.5A at 125V (300W). Some C5 connectors are rated higher.

You only need the most basic cable since iMac is only 150W.

Thank you for your help, JPack. Appreciate your help.
