What reviewers and owners say
r/nvidia · u/AccomplishedWill7083
CriticalAn owner inspected the unused 12v-2x6 cable from his RM1000x and found several quality control defects, including a badly crimped sense wire with exposed copper, a bent 12v conductor, and inconsistently seated pin inserts.

Common questions
Does the RM1000x need an adapter for an RTX 50 series card?
No. Corsair includes a native 12V-2x6 cable in the box, so no adapter is needed for cards that use that connector.
Can I reuse Type 4 cables from another Corsair unit?
Corsair states that Type 4 cables from its RMx, RMi, HXi and AXi series are compatible, but cables from other brands or connector types should never be mixed.
