CORSAIR teases a new direct-connect custom 12-Pin PCIe Power Connector Cable for Ampere RTX 30 series GPUs

It is no surprise that the Ampere lineup of cards have a higher power delivery requirement than previous gen of Nvidia GPUs, and the green team has also changed the power connector requirement for the Founders Edition cards. NVIDIA recently teased the RTX 30 series Ampere Gaming cards, and the company also confirmed a 12-pin power connector for the Founders Edition SKUs.

It has now been confirmed that the upcoming RTX 30 series Founders Edition cards will feature an irregular-shaped PCB, and also a 12-pin power connector as rumored before.

Now Corsair has recently shared an image of its upcoming 12-pin PCIe power connector cable, which is designed specifically for the Founders Editions RTX 30 series graphics cards. Nvidia has also promised to bundle an adapter that should be compatible with the existing 8-pin power cables. The cards will ship with bundled 2x 8-pin to 1x 12-pin connectors so you can run the GPU without any compatibility issues. The 12-pin connector will occupy less space than the traditional dual 8-pin cables. This connector will not require a new PSU though. This applies only to Founders Edition cards.

But according to Corsair, Nvidia’s solution is clunky and ugly, and it also increases resistance. That’s why the company is prepping its own custom design, which is a single cable that provides a direct power connection. Corsair plans to create a direct-to-PSU 12-pin GPU power connector for use with their modular power supplies. Corsair aims to create a thoroughly tested elegant cable which will allow Gamers to power 12-pin GPUs using a direct PSU power connection.

To quote Corsair:

“Our thoroughly tested solution is designed for those that have an eye for cable management and don’t want adapters cluttering up their clean builds. It connects two PCIe / CPU PSU ports directly to the new 12-pin connector.” “Fully compatible with all Type 3 and Type 4 CORSAIR modular power supplies, our new cable provides a clean direct connection without adding the resistance of a messy-looking adapter”.

Direct power supply connectors are more reliable and efficient than using adapters. More PSU manufacturers can expected to follow suit, and future power supplies are also likely to adopt Nvidia’s 12-pin GPU power connector standard. The new 12-pin connector is roughly the same size as a single industry standard 8-pin PCIe but can provide significantly more power in that same space. This has allowed NVIDIA to allocate the space previously used for power connectors to other things, like improved cooling.

And with Corsair’s solution being a complete cable rather than a pigtail-style adapter, it makes it easier to get the ball rolling without having to compromise on the pristine cable management.

The placement of the 12-pin connector on the PCB is very important to note here. Since it is placed in a vertical position, at a 45-degree angle, we can now tell why Nvidia moved to a single 12-pin cable instead of the traditional dual 8-pin design for these cards. These Ampere cards have a unique and new PCB design, and there appears to be limited room on the PCB for other stuff.

Nvidia explains: “Over the past 20 years, computer graphics have made huge advancements in performance. It takes a combination of expertise in architecture development, thermal, mechanical, electrical, and product design to make it all happen. We offer a first glimpse at some of the strides we have made in designing graphics cards, so that they can reach their maximum potential and remain cool and quiet”. These include:

  • Thermal: An airflow-optimized cooling solution, redesigned to overcome existing constraints and move more air through the system for maximum cooling efficiency.
  • Mechanical: A stronger mechanical structure, including a new low profile leaf spring that leaves room for a back cover.
  • Electrical:A compact electrical design, with a new 12-pin power connector that allows more space for components and cooling, and is compatible with 8-pin connectors in existing power supplies with an included adapter.
  • Product Design: A no-compromise, cohesive design that embraces the revolutionary thermal solution while beautifully harmonizing each element of the graphics card.

    1. Those supplies mostly differ in the PIN layout, just a revision model. Apart from that they are same. The only major difference between Type 3 and Type 4 cables is the pinout of the 24-pin ATX cable; all other cables (SATA, PCIe) are the same.

      The Type 4 cables have the same pin-out as Type 3 cables, but include small, solid capacitors on the +12V, +5V and +3.3V leads on the 24-pin, PCIe and EPS12V cables.

      The 24-pin of the Type 4 cable set also has a unique feature not implemented in the standard Type 3 cables. There are a total of 28-pins where the cable plugs into the PSU’s modular interface, instead of the usual 24-pins. The extra four pins are “sense wires”.

      While a +3.3V sense is part of the ATX standard and is found on most PSUs, it is not often implemented. For example the Corsair RMi PSU model not only utilizes the +3.3V sense on the ATX connector, but also utilizes an additional +12V sense and +5V sense.

      These sense wires read the voltages at the load (the end of the cable) and can increase voltage automatically if voltages drop.

      1. Silly of corsairs marketing team to not just list series/models and rather use an almost internal reference to them where a spreadsheet is almost needed to know what supports it.

        1. No, I think the FTW3 requires 3 × 8-pin cables. Check the following GPU database. Other EVGA models require 2 8-PIN connectors.

          Other GPU custom brand models, also require two or three 8pin cables/Power Connectors.

          Also, another thing to note. This generation of Geforce offers three options when it comes to the board design:

          NVIDIA Founders Edition (PG133)
          NVIDIA reference design (PG132)
          AIB custom designs

          The first two are not the same.The PG133 board design features an irregular V-shaped design, the iconic feature of the series. Meanwhile, the PG132 design is offered a regular, rectangular design for board partners who wish to create semi-custom designs (reference PCB and custom cooling) based on this CPB.

          The third option is obviously not going to fit any regular water block, as these cards have custom power delivery sections and component layouts. Some brands will offer water blocks for these custom designs, EKWB already confirmed it.

  1. Strange something like the 12pin didnt became standard when it started
    to get to 2×8, 1×8+1×6 or 2×6 etc. Cable clutter sux.12pin is most
    welcome
