This translates to lower electricity costs and reduced thermal stress on your components, making it a great long-term investment. Premium Components – Built to Last Corsair has packed the RM1000x with high-quality, 100% Japanese capacitors, which are rated for 105°C operation, ensuring durability and longevity. This power supply is built to handle continuous heavy loads while maintaining excellent reliability, making it ideal for enthusiasts, overclockers, and professionals who need uncompromising performance. Silent Operation – Zero RPM Mode A standout feature is the Zero RPM fan mode, which keeps the fan completely off during low to medium loads, resulting in silent operation. Even under heavy workloads, the 140mm fluid dynamic bearing fan runs whisper-quiet, ensuring a distraction-free experience whether you're gaming or working. Fully Modular – Clean and Hassle-Free Cable Management The fully modular design makes cable management a breeze. You only need to plug in the cables required for your build, reducing clutter and improving airflow inside your case. The included sleeved cables are of high quality and provide a clean, professional look. Reliable Power Delivery – Handles Any High-End Build With 1000W of power and a strong +12V rail, the RM1000x can handle high-end GPUs like the RTX 4090, AMD Radeon RX 7900 XTX, and multi-GPU setups with ease. It’s also perfect for overclocking, ensuring stable voltage delivery even under extreme loads.

    • The Gold Standard just got a major safety and control upgrade
Style: RMx (2024) - ATX 3.1 Size: 1000W
Corsair RM1000x (2024/2025 Refresh) I’ve been using the RM1000x series for years, but this latest refresh is a must-buy if you're running high-end hardware. Here is why this specific model is a step above the rest: The 12V-2x6 Safety Upgrade: This isn't just a rebranded cable. The 12V-2x6 standard fixes the "melting" issues from the older 16-pin designs by using shorter sense pins. If the cable isn't 100% seated, the PSU simply won't send full power, protecting your GPU from thermal damage. It's a huge peace of mind for anyone with a 40-series or 50-series card. Which was the exact reason I purchased it. If you are going to spend the money to buy the latest and greatest video card then by all means don't skimp on the power. Tactile Cooling Control: The Manual Fan Override Knob is a game-changer. It’s located right on the back panel next to the power plug, so it's fully accessible from outside your case. You can leave it on Zero RPM mode for total silence during work or manually crank it up to 100% during a marathon gaming session to keep the internals chilled. It's so satisfying to know that the fan that is inside PSU is not only running but as fast as you want it to because you can dial it in to your needs. Premium Internals: It uses 100% Japanese 105°C-rated capacitors, which are the highest tier for longevity. It’s Cybenetics Gold certified for efficiency and holds an A- noise rating, so even when it is working hard, it stays whisper-quiet. Build-Friendly Cables: The cables are "embossed," making them much more flexible and easier to route through tight spaces than the old stiff, sleeved versions. The Pro Tip: Register this PSU on the Corsair site immediately. It comes with a 10-year warranty. Corsair’s support is top-tier, and with a decade of coverage, this is likely the last PSU you’ll need to buy for the next several builds. ... show more
