Seasonic Outs 12-Pin Nvidia Power Connector, Lists 850W PSU Requirement

The , and meanwhile, the rumor mill is working as hard as it can to get you excited. We recently caught wind of and verified through our sources that such a cable does exist, and now a new picture of a 12-pin cable has surfaced - and it's purportedly posted by Seasonic, a PSU manufacturer. 

The leak was spotted by , who found the image on the . It shows a Seasonic cable next to its box, adapting dual 8-pin connectors into a single 12-pin connector. It's 750 mm long, and the box notes "It is recommended to use a power supply rated 850 W or higher with this cable."

As this cable features two male 8-pin connectors, it's intended to plug straight into the modular ports on a Seasonic PSU -- rather than to be used as an adapter on your existing 8-pin cables. 

Normally, 8-pin power connectors are rated for 150 W each, which paired with 75 W through the PCIe port tallies up to 375 W total board power. This isn't completely unheard of, as even custom boards from Nvidia's AIC partners occasionally have three PCIe power connectors. But note: this doesn't say much about Ampere's power consumption or efficiency.

The RTX 3090 was also , and it looks like it will be a behemoth of a triple-slot card, suggestive of a power-hungry design.

It's unclear whether this new 12-pin connector will make it to the entire Ampere GeForce line. The note on the box stating "It is recommended to use a power supply rated 850 W or higher with this cable" seems to suggest that it is only something that will be used on the most power-hungry cards, as we could imagine it would upset quite a large group of people if something like the RTX 3070 would also need a near-kilowatt PSU. 

That being said, it's also possible that the note is just there as a warning. After all, we can't deny that a single 12-pin connector would be a much more elegant solution than multiple connectors, especially if you decide to indulge in individually-sleeved cables. 

Either way, is by waiting for Nvidia's actual announcement, so just sit tight until September 1st.
