8639

Hello, I'm newbie and want to connect SAS disk to LSI 9341-4i PCI controller in my desktop PC. I tried to use this cable: SFF-8643 to U.2 SFF-8639 + SATA power. I can get into the controller's BIOS setup utility, but it's not seeing any HDD (NO PD PRESENT). Any of the disks doesn't even spin up...
