I believe my old BeQuiet PSU is a Seasonic one under the hood.
This new EVGA one though appears to be made by Super Flower.
I'll probably wind up being OK with the normal cables it comes with, but I guess it's possible I'll change my mind on that at some point.
I am really struggling to see why the new processors are so expensive, but oh well. I was tempted by an 8700K upgrade with a decent motherboard, but the 8700K has only gone up in price over the last year!
Just tallied up a ATX 24 pin, 2x8pin PCI-e bridged, 8pin EPS and a Sata cable with 4 ends on it, all Pro with 3 combs on each... came to €199.60 including shipping, guess I'll leave it for now...
No complaints for my 8700K, other than having to delid it to get the temps down to a reasonable level, I paid £395 for mine too, was back in November 2017 mind.
