Does the HX1200i Platinum ATX 3.0 support 12VHPWR / 12V-2x6 connectors?

The introduction of RTX 40-Series graphics cards brought us the 12VHPWR PCIe 5.0 power connector. The goal was to bring all the necessary power of up to 600W to graphics cards with a single connector instead of relying on several 6+2 Pin connectors. The result, the 12VHPWR connector is a space saving solution that can supply enough power to modern graphics cards utilizing sense pins that let the graphics card know how much power it's allowed to draw from the connected power supply unit.

You've probably heard about insufficient connections of said 12VHPWR connectors leading to connectivity issues. To remedy these issues, we now have an improved version of the 12VHPRW connector that does come with a renaming as well. It is now called 12V-2x6.

Yes, a flat 12VHPWR cable capable of supplying up to 600W is included and you can simply use that cable to connect to your RTX 40-Series graphics card.

The answer is no, you don’t. The cables and adapter for 12VHPWR are backwards-compatible and can be used with the 12V-2x6 connector. All that has been changed is the length of the sense pins within the actual connector. The have become shorter to ensure the cable is properly seated reducing the chance of improper connections.

Looking for an angled adapter? We have you covered, our PCIe 5.0 12VHPWR GPU Power Bridge is a great solution to adapt the 12VHPWR or 12V-2x6 connector on your compatible (see compatibility table on our product page) graphics card by 180°.

The CORSAIR HX1200i PLATINUM ATX 3.0 power supply unit comes with a 12VHPWR cable in the box. It connects to two PCIe / GPU connectors on the modular side of the GPU. There are six total connectors available on the power supply to connect additional 6- and 6+2-Pin cables when needed. These are for example needed for our iCUE LINK System Hubs. With the HX1200i you will not need to worry about running out of available modular connection points anytime soon.

Each of the ports can deliver 300W+ so you don’t need to worry that there is not enough power available. With the 12VHPWR cable you are ready to supply up to 600W to the graphics card of your choice, be it the RTX 4080 Super or the most powerful RTX 4090 and it does not matter if the card you choose uses the 12VHPWR connector or the updated 12V-2x6 one.

If you already own a CORSAIR branded individually sleeved cable you are all set. HX1200i uses Type 4 CORSAIR cables. If you are looking for a sleeved cable to improve the overall look of your build, you can simply buy one of our Premium Individually Sleeved 12+4pin PCIe Gen 5 12VHPWR 600W cable, Type 4 cables and use them with your graphics card that has a 12VHPWR or 12V-2x6 connector. Our premium sleeved 12VHPWR cables come in black, red/black, white, and white/black.

Looking to replace the other cables too? There are two kits that will meet your needs. One being the Premium Individually Sleeved PSU Cables Pro Kit Type 4 Gen 4 and the other one being the Premium Individually Sleeved PSU Cables Starter Kit Type 4 Gen 4. The difference between the two is the number of cables in the kit. For most setups the starter kit will be sufficient but if you are using a motherboard that has two EPS12V connectors, you will need to add another Premium Individually Sleeved EPS12V/ATX12V Cables Type 4 Gen 4 cable to your shopping basket. The Pro Kit already has two EPS12V cables in the box.
