The most power-hungry graphics card that fits, by desktop model
Board power is the figure that decides whether a supply can feed a card, but manufacturers do not publish a maximum for the machine. This list does not invent one. Each row shows the highest board power among the cards that carry a fitting verdict on that machine's own page — a floor established by the cards this database happens to hold, not a ceiling stated by anyone. A machine may well accept a hungrier card that is not listed here.
We have not physically tested this combination. Data is compiled from official specification sheets and cited sources. Verify with the manufacturer before purchasing.

|---|---|---|---|---|---|
| Dell Precision 3660 Tower | Tower (mini tower) | 300 W | NVIDIA RTX A6000 | 300 / 500 / 750 / 1000 W | Standard PCIe 6-pin and 6+2-pin (equivalent to 8-pin); not a proprietary connector. 300 W: no connector. 500 W: one 6-pin plus one 6+2-pin. 750 W and 1000 W: two 6-pin plus two 6+2-pin. |

| Dell OptiPlex 7040 Mini Tower (2015) | Tower (mini tower) | 75 W | AMD Radeon R7 250 (Reference design) | 240 W | No power-supply configuration has an auxiliary power connector; the official manual states none and it could not be confirmed in Dell's official community forum either. Supporting evidence: in the official Owner's Manual, table 11 "internal connectors", the power connector row lists only an 8-pin for the power supply, a 4-pin for the processor and an 8-pin for SATA power, with nothing for a graphics card, and the machine has a single 240 W supply. Absence from a list is not treated here as proof that the connector does not exist, but it is consistent with the rest of the evidence. |
