Seasonic Provides First Images of NVIDIA 12-pin PCIe Molex Connectors

Last month, we heard a rumor regarding NVIDIA’s GeForce RTX 30 series graphics cards. We learned that it will use an entirely new power interface to facilitate higher energy draws with the main graphics cards for games. And now, we can finally confirm this almost formally, as one well-known power supply manufacturer PSU (Seasonic) has published photos of the 12-pin NVIDIA PCIe Molex Power Supply Adapter.

Posted by Seasonic in Chinese media portal Bilibili (by HXL @ 9550pro) leak, it shows a box containing the new NVIDIA 12-pin PCIe Molex Micro-Fit 3.0 connector. The Molex connector is packaged inside a cardboard box and contains a 12-pin power connector that draws its power through two 8-pin connectors directly from the power supply.

The new 2x 8-pin to 1x-12-pin power connector has a length of 750 mm which should be enough for most modern case boxes and assemblies. Seasonic has published a power supply rating of 850W or more for use with the new 12-pin connector cable.

Depending on their appearance, it appears that NVIDIA GeForce RTX 30 series graphics cards may only have a single 12-pin connector since it draws power from two 2x 8-pin connectors that will provide a power draw of 300 watts (150 watts per 8-pin header). Years). The PCIe interface itself provides 75 watts of power to the graphics card, which will be sufficient for the graphics card by a large percentage.

What we don’t know is how Seasonic and other power supply makers will provide these inverters. Sure, all new power supplies will be bundled with the new cable, but what about those who already own power supplies ?! Unless shipped with the Founders Edition graphics cards, they may have to purchase the cables separately.

According to the official Seasonic account, the 12-pin connector has been used extensively by NVIDIA for internal testing and it is unlikely that the graphics card makers will ship the switches themselves because the specifications for the 12-pin switches are different and must match each manufacturer’s power supply specifications differently. Hence, it can only be provided by the power supply suppliers themselves.

The Founders Edition cards are also expected to feature more than 20 power coils, making it a more premium design than the standard RTX 20 series flagship cards. While the Founders Edition cards feature 12-pin power connectors, custom designs from third-party companies will still use the standard 8 and 6-pin connectors as shown in previous leaks.
The NVIDIA GeForce RTX 30 Ampere cards are expected to be announced on September 1st at a digital event hosted by NVIDIA CEO Jensen Huang. We expect at least three new graphics cards to be available at the event which will include GeForce RTX 3080 Ti (or RTX 3090), GeForce RTX 3080 and the next generation Titan card.
