Seasonic confirms Nvidia’s 12-pin Micro-Fit 3.0 Power Connector

Rumour has it that Nvidia has been working on a new 12-pin GPU power connector for its power-hungry RTX 30 series flagship. Now, Seasonic has confirmed that this connector exists and that it will be available as an adaptor for its power supplies. 

This new 12-pin connector will be smaller than today’s 8-pin PCIe power connectors. This change will allow graphics card makers to deliver more power over a smaller connector, saving precious PCB space while also reducing the number of cables that are required to power a flagship-level graphics card.  

Recently, images of Nvidia’s alleged RTX 3090 Founders Edition design have leaked onto the web, revealing a colossal triple shot graphics card which dwarfs anything that Nvidia has previously created. This suggests that the RTX 3090 will run hot, necessitating a lot of power draw. 

Seasonic’s Micro-Fit 3.0 connectors are designed to fit directly onto the manufacturer’s power supplies. At this time it is unknown how widely these cables will be shipped to retailers, or if Nvidia plans to bundle similar adapters with applicable RTX 30 series graphics cards. Seasonic recommends that these cables are used with 850W or higher power supplies.

Please note that these adapters will not be compatible with all power supplies, as different manufacturers use different pinouts on their units. Using adapters like this, which connect directly to your power supply, on the wrong power supply units could potentially destroy your hardware. Always be careful when using PSU adapters.
