Board & Power Supply
Asus uses its own design for this board. Behind a pair of eight-pin auxiliary power connectors, the board has two chokes to smooth out spikes in the electrical input.
The ROG Poseidon GeForce GTX 1080 Ti 11GB Platinum Edition employs a 5+2-phase power supply with doubling. Thus, each phase is able to distribute the load between two parallel control circuits. You can see the memory's two phases on the card's top-left.
Asus keeps the back of its card tidy-looking. It's home to the memory's PWM controller and a number of other components.
