Contact nzxt and explain your problem.
Perhaps they have an old or new style panel with the proper plug that will fit your needs.
I have a NZXT H440 Razer edition and had the front led logo + the psu shroud led logo die on me. NZXT to their credit sent me a replacement shroud+front panel however upon arriving they appear to have changed the connectors they use.
Old led cable vs new led cable. Now given they are meant to connect to a controller via cords like this, the pins on the new cables are just far too wide.
Any suggestions how to power these, perhaps directly through the PSU via a molex adapter etc?
Thanks in advance
