Super-flower 1000w "platinum" popped + smoke after upgrade to RX590

[Dj_Jestar]

Hello there.

6 years ago I bought a Super-flower 1000w which happily ran a 780ti for almost 5 years (the 780ti finally died in 2018.) Fast forward to this week, I bought a RX590 card, which after just a couple of days has literally popped the channel is was plugged into. The card and other channels on the PSU are still working (as well as the rest of the hardware).

Is this something that I've got wrong? Too much/little power through the channel? Is there some other kind of fault I should be looking for before I replace the PSU and use the machine again? Or just "old" PSU?

Thanks

It had it's own channel, but this PSU doesn't have a dedi 8pin only the "universal" 9pins:

It was definitely the PSU. At least that's what my nose is telling me after pulling everything out and having a good sniff.

Noted about the split cable, thanks.
