Debuting with the GeForce RTX 3090 Ti is a new 16-pin ATX power connector for graphics cards that reduces the number of cables running from the power supply while meeting growing power requirements. The source recalls that some RTX 3090 Ti PCBs provide the ability to install a second 16-pin connector.The Galax RTX 3090 Ti HOF is said to be the first such card.
Theoretically, two 16-pin connectors can power a video card that consumes up to 1200 watts. The Galax HOF series is aimed at overclockers who need a stable power supply to achieve record-breaking overclocking performance.
The specifications of the Galax RTX 3090 Ti HOF are 480W, and the special P mode is 516W, which is more than the capacity of three 8-pin connectors that can be connected to one 16-pin with an adapter. Two 16-pin connectors means two adapters can be used, giving a total of six 8-pin inputs and up to 900W of power.
