Check power connector: RTX PRO 6000 needs 12VHPWR/12V-2x6
On older units without an ATX 3.0 connector the card only runs via adapter. That works, but it is the most common failure point under load spikes – a PSU with a native connector is the safe choice.
Adding a second compute-focused card provides the necessary overhead for AI/ML development. Upgrading the PSU ensures that the combined power draw of a dual-GPU setup remains well within efficiency limits without risking instability under peak load transients.
