I obviously didn't describe my concerns very well, I'm not bothered in the slightest by being able to see a bit of cable. My concern was having to deal with 3 x 8-pin connectors. In the example picture it's fine, but what if your case doesn't have a gap to pass through right at the exit point? Also in my experience of cable management that section is usually one of the busier points behind the motherboard tray to suddenly add 3 x 8-pin connectors to.
Makes you wonder why everyone has a go at Nvidia for any issues with it.
I think it's fine if AMD do it.

But yes it does seem to go against the advice we got with these connectors. I'd say you'd think Sapphire would've tested it, but then you'd have thought Nvidia and it's board partners also did some testing but it didn't prevent issues with the connector.
