The Corsair RM1000x is a high-capacity, fully modular ATX power supply designed for power-hungry builds. With 1000W of clean, stable power and Cybenetics Gold efficiency (up to 91%), it's an excellent choice for high-end gaming rigs, workstations, and content creation systems. It fully complies with Intel's ATX 3.1 standard, including a native 12V-2x6 connector for the latest graphics cards.
Corsair's RMx series is known for low-noise operation. The RM1000x uses a 140mm fluid dynamic bearing fan that spins only when needed, keeping things silent under light loads. All cables are fully modular and come with low-profile combs to keep your build clean and organized.
Managing cables is easier with the embossed, ultra-flexible cables. They're designed to route seamlessly around corners and through tight spaces. To organize your build, consider these tips:
With 100% Japanese 105°C-rated capacitors and a 10-year warranty, the RM1000x is built to last.
Fully modular cabling with embossed, ultra-flexible cables and low-profile combs for clean builds.
Cybenetics Gold certified (up to 91% efficiency) for lower energy bills and quieter operation.

Cable management made simple: the embossed cables are pre-shaped to curve neatly, and the included combs keep everything aligned. The side-mounted connection panel (note: standard layout here) allows easy access to all ports, so you can swap cables without digging inside your case.
Yes, it has a native 12V-2x6 connector, so you can plug directly into RTX 40-series and newer graphics cards without an adapter.
Slide the combs onto the cables and position them to keep the wires aligned. For the 24-pin, place combs at each bend to maintain a neat, flat run.
The RM1000x is a standard ATX PSU, so it requires a case with ATX PSU support. Consider an SFX or SFX-L model for SFF builds.
Cybenetics is an independent testing organization. Gold certification means the PSU achieves up to 91% efficiency at typical loads, reducing heat and power waste.
The RM1000x is reliable and quiet. The 12V-2x6 connector is perfect for my RTX 4090. Fully modular, so cable management is clean. Cybenetics Gold rating is a nice bonus. Highly recommend.
It's a quality unit with all the features you'd want. The native 12V-2x6 is a plus. The only issue is that it's long, so it might not fit in smaller cases. Make sure you have the space.
I needed 1000W for my high-end build, and this PSU delivers. It's very efficient, and the fan is silent under normal load. The fully modular cables make building easy. Excellent product from Corsair.
It works well, and the performance is solid. However, the cables are a bit stiff, which makes routing them a challenge. Also, the 12V-2x6 cable is thick and hard to bend. But it's a reliable PSU.
With ATX 3.1 and the native 12V-2x6 connector, this PSU is ready for modern GPUs. I'm using it with a 4090 and it handles everything perfectly. The build quality is top-notch, and it's quiet. Worth it.
It's a high-quality power supply, but you're paying a premium for the ATX 3.1 and Cybenetics Gold. Performance is great, and it feels robust. If you need the 12V-2x6, it's a solid choice.
I've been running this PSU for months without a hitch. It provides steady power and doesn't get hot. The modular design is convenient, and the black finish looks good. Definitely recommend.
The PSU performs well, but the fan noise is a bit higher than I expected under load. It's not obnoxious, but it's audible in a quiet room. The 12V-2x6 connection is secure. Overall, it's okay.
This is the third Corsair PSU I've owned, and they never disappoint. The RM1000x is efficient, silent, and powerful. The native 12V-2x6 is perfect for my new GPU. Highly recommended.
Everything works well, and the PSU is efficient. However, the cables are a bit short for my full tower case. I had to use extension cables for some connections. Other than that, it's a great unit.
I bought this for peace of mind, and it's been perfect. The build quality is outstanding, and it looks great. The 12V-2x6 connector is easy to use. I've had no issues with it. Five stars.
I'm disappointed. The PSU works, but it has a noticeable coil whine when under load. I tried multiple outlets and it persists. Corsair support offered a replacement, but I'm not sure if the new one will be the same. Not happy.
