Just comparing the zoomed in photos on newegg, the cpu or 8 pin on the Seasonic x-850 differs from the Corsair ax850.
I have the Seasonic x-850, and with a magnifier on the plug, I can see the difference between my Seasonic 8 pin and the newegg foto of the Corsair ax850.
Not that its proof, but I see a difference.
But agreed on the peripherals - different sockets/connectors arrangement between the Corsair ax850 and Seasonic x-850 models.
Trying to decide how to go on sleeving - pre-sleeved, pay the man Lutro0 when he's settled/working/comfortable, or .... \shudder/ - d.i.y.
