GALAX RTX 3090 Ti HOF First Graphics Card with Dual 16-pin Connectors (1200W Input Capability)

The GeForce RTX 3090 Ti debuted the new ATX 16-pin power connector for graphics cards, which minimize the cable clutter in your case, while meeting the growing power demands of graphics cards as Moore's Law buckles. During our reviews of the RTX 3090 Ti, we noticed that a handful graphics card PCBs had provision for a second 16-pin connector (implying that the first one with a maximum of 600 W of power delivery is maxed out).

GALAX debuted the first graphics card with two 16-pin connectors, a theoretical power input capability of a whopping 1200 W. At first we thought this is an exercise in absurdity, until we took a close look at our numbers again. Currently, ATX 3.0 PSUs with 16-pin connectors are extremely rare, and so every NVIDIA board partner is required to include an NVIDIA-developed adapter that converts three 8-pin PCIe power connectors to one 16-pin. Three 8-pin connectors only add up to 450 W, whereas in our testing we noticed that some of the cards were peaking well beyond 450 W, despite using this adapter.
