No they just sent a generic C14 cut to the same length that doesn't fit into the cutout. I didn't even try to squeeze it in as it was obviously not a correct fit. It did fix my intermittent freezing/shut down issues though (sounds like a few more and I'd have a fire on my hands :3)Quick question. Is this the cable you're talking about?
I recently saw someone say that ZS had changed the cable to this one, which is different than the one they showed in the C14 update.
