Yeah, I had a pretty good feeling about it going in though. The fact that it ran perfectly OK basic on the desktop, but insta-shut down when it got a heavy load gave me a good feeling it was going to work.

I almost wonder if I should mention anything to MicroCenter about how their EPS extension cable...

I'm not looking for anything from them, but it might prevent this from happening to anyone else...

What are you going to tell them?

I don't know.. Maybe suggest they replace it in their stores with an extension with lower gauge wires?

In my case things worked out OK, but I'm a pretty seasoned builder, and if I didn't think to check the gauge of the extension, I'm betting almost no one does.

Last thing they want is someone burning down their house due to a cheap extension cable they bought at MicroCenter...

Heck, I don't even know if they sell the one I bought there anymore.

Alright, strike that. I misremembered. Looks like I ordered this one on Amazon. I'm going to leave a review. Turns out I'm not the only person to have an issue with this cable.

I'm surprised a cable can fry like that without some collateral damage occurring.

Im using an extension on mine, but mine is like ten times higher quality cable lol.....IM pretty sure its still in use for my current pc just located on the back side of my case so its impossible to see without pulling the back cover off. Seems like i hand picked mine off ebay when i got mine. Mine is like 3 times as long....good grief that little ext wasn't made to help much


My guess is it was the cheap connector on the extension cable in this case. Resistance in the connector heated it up eventually causing the connector to fail and short-out, resulting in a large current flowing through the wire and melting the insulation. Extensions on such high current cables should be avoided.

Connectors like that usually fry because of a bad pin crimp in the connector. The heat just travels up the wire because metal conducts heat pretty well. Larger gauge wire (smaller number) would help, but doesn’t make up for shitty QC or cheap lowest bidder automated construction process — the connector would still melt out, the insulation burns up as the heat travels, then you get wire to wire or wire to ground shorts and that’s when things get interesting.
