1000W Corsair RM1000x Modular 80 Plus Gold PSU CP-9020271-UK

The CORSAIR RMx Series has been powering top-performing PCs for years. These fully modular lownoise PSUs are 80 PLUS Gold-cer... moretified for up to 90% efficiency and Cybenetics Platinum-certified for lower power consumption, less noise, and cooler temperatures. Fully modular cables make PC builds easy, as you connect only the cables your system requires. RMx PSUs are compliant with the ATX 3.1 power standard from Intel®, supporting the PCIe Gen 5 platform. A native 12V-2x6 connector ensures compatibility with the latest graphics cards with a direct GPU to PSU connection, without the need for an adapter. With 100% Japanese 105°C-rated electrolytic capacitors, the electric performance of the RMx Series is outstanding. Featuring resonant LLC topology with DC-to-DC conversion, you can be confident that your PSU provides clean, consistent power while also enabling the use of more energy-efficient sleep states such as Modern Standby. Keep the noise down thanks to a 140mm proprietary FDB fan, using a specially calculated fan curve for low noise operation even at full load. A built-in fan speed adjustment knob on the back of the PSU also gives you quick manual control. At low loads, Zero RPM fan mode support results in near-silent operation. With a 50°C maximum operating temperature, an RMx PSU can handle all the stress you can throw at it. A six-layer modular PCB provides improved voltage stability and heat dissipation. Backed by a ten-year warranty, the CORSAIR RMx Series will be the gold standard for many years to come.

You can take it, but there is a nuance
12 July 2025 
Purchased in June 2025, at that time I had a Ricsa 6600, nothing special, 8 pin power. A month later, I bought a 5070ti and decided to power it through 12v 6x2, everything worked, but!!!! As soon as I started loading a game, the computer rebooted... (I inserted the connector all the way in, so there can't be a mistake here) I thought it might be the system, maybe a driver conflict, maybe I deleted something using DDU when I was cleaning the system from an AMD driver. But I remembered that this can happen when there's not enough power for the video card, when capacitors are bloated.

I decided to try the included adapter that came with the video card, and everything started working)))
You're almost there
Doesn't work as desired 12v 6x2
