Throw down a bit of a safety factor, and we're at 600W. Maybe tolerances / manufacturing has improved to the point where they feel its safe to improve the specifications of a new connector?ĮDIT: Molex claims that micro-fit connectors can support 10.5 Amps ( With 12-connectors, but 2-connectors per circuit (positive + negative leads), that's 10.5 Amps x 12V x 6 connections = 756W per 12-pin connector. These old 6-pin 75W and 8-pin 150W connectors were made from decades ago.
If the connectors are better "matched" and have a greater surface area / contact area due to improvements in manufacturing, its probably possible. thinking about it more seriously, it could be a tolerance thing. MouacykHow can something smaller and tightly packed sustain a higher load? Are the wires actually thicker? I've had enough PCI-e and EPS connectors melt on me to wonder.Hmmm. Posted on Aug 23rd 2020, 22:40 Reply #14 JustAnEngineer We might get away with two if they're very well constructed, but even that is exceeding the design limits of the 8-pin PCIe standard.From what I have seen it is the equivalent of two 6 pin connectors, the same gauge wire and quantity of positive and negative, only a higher power drawn through the connector from the PSU. Running two or three times the rated current through the single cable would risk melting the insulation and starting a fire. Therefore, it isn't safe to power the new 600-watt micro connector with adapters from a single 150-watt 8-pin PCIe connector. JustAnEngineerIf the options are three 150-watt 8-pin PCIe connectors or one of the new 600-watt 12-pin micro connectors, we can deduce that the graphics card needs between 376 and 525 watts of power and 301 to 450 watts of it is coming through the external power connector. So really no hoops if they do that.Or sell it as an accessory at top dollar like they did with the HB Bridge when they first came out.

The space-saving connector shouldn't just be easier to plug in, but also cable-manage, since you're only having to wrestle with one cable, even for a high-end graphics card. It yet uses high gauge wires and pins, so it can push up to 600 W of power - more power than two 8-pin connectors. The publication's editor Andreas Schilling posted this striking picture that is sure to change our perspective about the 12-pin connector - it is tiny!Ĭalled the Molex Micro-Fit 3.0 12-pin connector, the NVIDIA 12-pin connector looks visibly smaller than a single 8-pin PCIe power connector, and only slightly broader. received a set of modular cables by Seasonic that can be plugged into the company's modular PSUs, directly putting out a 12-pin connector. Over the weekend, we got some of the first pictures of a production-grade NVIDIA 12-pin graphics card power connector that debuts with the company's GeForce "Ampere" Founders Edition graphics cards.
