NVIDIA "Ampere" 12-pin Power Connector Pictured Some More

Korean tech publication QuasarZone posted three high-res pictures of the new Molex Micro-Fit 3.0 12-pin connector that NVIDIA adapted for its GeForce "Ampere" graphics cards, at least the reference-design Founders Edition ones. As we detailed extensively in an older article, the 12-pin connector has significantly smaller pins than the standard PCIe power connectors, and is only slightly longer than an 8-pin PCIe power connector. Placed side by side, you can tell how the PCIe connector is taller, if not wider. Despite its relatively compact dimensions, the 12-pin connector is rumored to be rated for a significantly higher power delivery than the 8-pin connector, with some of the oldest reports even suggesting 600 W. The cables going into the 12-pin connector appear to be of a higher gauge than the ones making up the 8-pin. NVIDIA in a video presentation released on Wednesday explained how it plans its upcoming GeForce graphics cards to address many fundamental engineering problems with modern graphics cards, in the areas of efficiency heat dissipation, board durability, and power delivery.

Tiny Pin ? Can they handle up to 8 amp per pin? I think it's up to 6 or up to 432w.

It’s rated for 5A per pin by IEC. They say that nvidia manufactures the socket side themselves (so it’s not a molex part), so that rating might not apply anymore.

The new 12-Pin connector does seem to use a thicker cable despite its size, so it will definitely handle higher current.

dj-electricThere's nothing secretive or special about "the new" Molex micro fit connector
www.molex.com/molex/products/part-detail/crimp_housings/0430251200
The industry has been using it for years, and will continue to do so.

If you want to know anything about it, just go to its datasheet and read about it.
I looked at test summary and Source : www.molex.com/pdm_docs/ps/PS-43045-001.pdf

Page 8 (CURRENT DERATING REFERENCE INFORMATION ) , with 18 AWG wire , for 12 circuit = 5.5 amp per pin.

so this is what 12V only motherboards are using. well just for the 5V3V, 12V 10pin is still using the big chunky plug. what a mess. just transition everything to microfit at once in one generation.

No. This is for GPUs...the 12V connector for motherboards is 10-pin as you mentioned. It is a fatter connector though.

Yes, Founders' cards will ship with adapter.

Why would it need to? It just has to cope 2x8pin pcie power thus 2x150W=300W so 5A per pin, which is within the molex spec. Anything else is just confusion or misunderstanding. In real world two 8-pins can handle more power than this(9A per pin).

Propreitary garbage and unusual cooling to dump the heat onto CPU and RAM and other components. This is a waste purchase esp given we do not see any of the Ti too, no one should buy these Reference cards. Wait for AIB and get traditional power.

How is molex proprietary?

Is the output on this 12-pin connector 12v-only?

If so it might be a good transition to the next PSU standard being purely 12v output.

Wouldn't 5A per pin only supply 360W? (12 pins x 12V x 5A / 2: where "divided by 2" is because +power must also travel to the -power pins).

EDIT: Also +75W from the PCIe connection. So I guess 435W. IIRC, rumors are that this is a ~400W board, so I guess 5A per pin + 75W PCIe connection is within specifications. 2x8 pin is 300W (150W per 8-pin connector).

Wow, trying to build hype by leaking power connectors.
How innovative.

And in every thread we find the same people, so it seems to be working.

I'm just talking about those 12 pins so they can't handle more amp than those 2x8 pins.What I thought that 12 pins is equal or better than 2x8 pins which is not true

or perhaps Nvidia wants to have better power management ?

Hi,
It's already been posted this is all about builders complaints
It's too tough to run 2x 8 cables for one gpu and looks bad x2 for sli...
It's a lane reason.
Hopefuly evga will ignore this new plug.

One plug smaller than two existing ones combined (and in fact smaller than single 8-pin one) is somehow worse for cable management? :confused:

Hi,
No I'm saying this new plug is more about cable management than new break through power delivery lol

Exactly, more compact for clean build especially for sli as you mentioned above.
I'll take this 12pin anyday
