Is this PSU good enough for my new system and does it have all the cables for connecting to the GPU?

My RM850x just arrived today but it does not have 3 PCIe 8 pins cables included. Only 2 PCIe cables are in the box.

So i can not use this PSU for my RTX4080 to connect to the 12vhp adapter? Do i need to send it back and buy another brand?

Please help me.

Will this cable give me enough power to the 4080 (max320watt) with a RM850X PSU? Because Nvidia says you need 3 seperated cables conected to the nvidia adapter.

you need 3 PCIE connectors to use THEIR adapter.. the PCIE connector (the one on the GPU side) is rated to 150W maximum.

the corsair cable does not use those connectors so it can draw up to 600W from two cables. The corsair 12VHPWR cable will work just fine since you'll use it at half its rating.
