Who it’s for / pitfalls
Good for
- People powering an RTX 50-series class GPU who want a native 12V-2x6 cable
- Builders who like fully modular cabling and low noise at light loads
Not for
- People whose GPU plus CPU draw is near or above 850W and need more wattage
- Small-case builders without room for a standard ATX power supply
Known pitfalls
- The fan stays off at low loads; a manual fan override knob lets you force airflow
- The listed 12V-2x6 GPU cable is 650mm, so measure the route in a big case first
