Promotional tone

to tap into the performance capabilities these units can offer.

The 16-pin 12vHPWR connector has been instrumental in enabling the development of more powerful GPUs, giving rise to a new era of high-performance computing, gaming, and data processing. It has opened up new possibilities for GPU-accelerated applications

That is nothing. Here we go: https://wccftech.com/12v-2x6-h-connector-offers-675w-gpu-power-delivery-versus-600w-12vhpwr-h-plug/ Valery Zapolodov (talk) 02:57, 12 March 2024 (UTC)

"Rated Power" is that continous or peak power rating?

Question is, is there an 80% rule that should be followed? So would be a limit of 480w continuously if over 3 hours duration, 600w peak? Does the specification specify whether "Rated Power" is continuous or temporary? I feel it is rated for continuous otherwise nVidia would not have made the decision of a single connector.

Very good question! I got my hand on the spec, it says up to 55 A of continuous current to provide a maximum of 600 W of power – the power would also be continuous per logic. Also current rating: 9.2 A per pin/position at minimum would also be continuous. Due to variations in contact resistance, an individual pin may see more than 9.2A of current depending on cable contact resistance nonuniformity, but the total current for the assembly shall not exceed 55A RMS in each direction. is very lax on the problem of current distribution and leaves it to the implementer to ensure nothing is burning. Accordingly, it's quite possible to have on-spec cabling and still suffer thermal damage due to single contacts being overly stressed. YMMV. --Zac67 (talk) 11:32, 12 February 2025 (UTC)

"These flaws are currently only present on the RTX 5090 FE."

It's my understanding from watching videos from Buildzoid (Actually Hardcore Overclocking) and others that all models of 5090 and 5080 would be affected, because the PCB design 'merges' all power into a single 'blob'. Not a technical explanation I know. Even the 5090 Astral, with separate detection design, could still be impacted - albeit the user is hopefully warned before something melts. — Preceding unsigned comment added by 152.37.65.140 (talk) 15:18, 17 February 2025 (UTC)

Effectively the conductors were tied to a busbar and current limiting was done after that. The issue being a busbar will happily draw all current through a subset of the conductors, not limiting the current drawn from any one conductor.

The seems as if the design incrementally evolved from earlier designs and the engineers didn't realize they had left their area of expertise. The remedy mentioned, moving the sense pins further in, would work well for connectors similar to SATA power connectors. For SATA power connectors the lower current draw requires less contact area and less force on the pins, which means the pins move very little during connect/disconnect. The 12VHPWR connector seems more similar to a molex connector where greater contact area means greater force and the pins move far more. Hence the safety issues are very different. 74.104.188.4 (talk) 02:26, 14 April 2025 (UTC)

16-pin 12VHPWR connector → ? – The current title is too wordy. I am unsure what a better name is, but "16-pin" should at least be removed because these connectors are 16-pins already per the spec. Should it be "12VHPWR connector", "12V-2x6 connector", "12VHPWR", "12V-2x6", or something else?

Support move to 12VHPWR, just like ATX, has no "form factor" or "specification" after it. UU (talk) 14:33, 26 April 2025 (UTC)

12 pin Image

The image shows a 2x6 pin connector which is only 12 pin. This inconsistency should be fixed. AMD uses 12V-2x6pin yes, but it makes sense to differentiate. — Preceding unsigned comment added by ~2026-23576-42 (talk) 17:05, 16 April 2026 (UTC)

The article has only 4 images. The 3 with visible pins all seem to be 16-pin. So I'm perplexed as to what you're referring to. Note that the 4 lower sense pins are much smaller than the 12 main pins. Cybercobra (talk) 05:39, 17 April 2026 (UTC)

It was my error. I didn't notice the front pins. ~2026-23576-42 (talk) 18:19, 18 April 2026 (UTC)
