CORSAIR RM1000e (2025) Fully Modular Low-Noise ATX Power Supply with 12V-2x6 Cable – ATX 3.1 & PCIe 5.1 Compliant, Cybenetics Gold Efficiency, 105°C-Rated Capacitors, Modern Standby Mode – White

I haven't run into some of the issues others have for this power supply, but I'm also not an expert user. It works, it's quiet, and the build quality seemed ok to me. It fit in my case easily enough, screws all went in without issues, and the cables feel very nice. It came with screws and some zip ties which were helpful!

Por el precio vale totalmente la pena. La calidad es excelente, los materiales se sienten premium y es muy silenciosa incluso bajo carga. Al ser totalmente modular facilita mucho el armado y el manejo de cables. Muy buena opción para un equipo actual y a futuro.

Perfeito

I recently purchased the Corsair PSU, and I must say that I was pleasantly surprised by its quality and performance. At first, I was a bit skeptical about spending money on a high-end PSU, but now I can see that it's definitely worth it. The PSU itself is very well-built, with a solid construction and a sleek design. The modular cabling system is also a great feature, allowing me to remove any unnecessary cables and keep my system looking clean and organized. One of the things that really impressed me about this PSU is the variety of cables that come with it. I was able to find the perfect combination of cables to fit my specific needs, and the included cable management system made it easy to keep everything tidy. In terms of performance, the Corsair PSU has been rock-solid. I've been running my system with a variety of components, including a high-end GPU and CPU, and the PSU has handled everything with ease. The power delivery is smooth and consistent, and I've noticed a significant reduction in noise and heat compared to my old PSU. What's even more impressive is that this PSU is very affordable, especially considering its high quality. I was expecting to pay a lot more for a PSU of this caliber, but Corsair has managed to offer it at a very competitive price. This makes it an excellent value for anyone looking for a high-quality PSU without breaking the bank. Overall, I'm extremely happy with my purchase and would highly recommend the Corsair PSU to anyone in the market for a new power supply. Its combination of high quality, excellent performance, and affordability make it a standout in its class, and I'm confident that it will serve me well for years to come. Whether you're a gamer, a content creator, or just someone who wants a reliable PSU, the Corsair PSU is definitely worth considering.

I’ve been building PCs for over a decade, and this is easily one of the most impressive power supplies I’ve used to date. I picked up the CORSAIR RM850e (2025 revision) as part of a rebuild centered around an Intel i9-12900KS and RTX 3090, and I’ve been nothing but impressed so far. Build Quality & Design: The unit itself is solid — heavy in a reassuring way, with a clean black finish and no unnecessary branding or flashy extras. The fully modular design is a huge plus, especially for managing cables in a tight mid-tower. I appreciated that the included cables were all black and flat — easy to route behind the motherboard tray, and they look clean without custom sleeving. Installation & Cabling: Installation was simple, and everything fit snugly. I’m using the standard 3x 8-pin for the 3090, but it’s nice knowing the 12V-2x6 cable is included in case I upgrade to a future PCIe 5.1 card later on. No loose connectors, no weird bends required — and unlike some modular PSUs I’ve dealt with, the ports on the unit are clearly labeled and firmly seated. Performance & Stability: Despite powering a very power-hungry setup, this PSU hasn’t flinched once. The 12900KS, even under boost/load, can be a voltage-hungry CPU, especially paired with the 3090 — but even during max load stress testing (Cinebench + Heaven benchmark running together), rails stayed completely stable, no crashes or brownouts, and no sign of power-related instability. Noise & Efficiency: Corsair nailed the noise levels. During idle and light gaming, the fan doesn't even spin up. Even when it does under load, it’s so quiet it fades into the background of my other case fans. My case has good airflow, but the fan curve on this PSU is genuinely impressive. It’s also Cybenetics Gold rated, and the system draws power very efficiently — I've been monitoring wattage via a smart plug, and it lines up well with published benchmarks for power efficiency. Extras & Future-Proofing: ATX 3.1 & PCIe 5.1 ready 105°C-rated Japanese capacitors (a must for long-term reliability) Modern Standby support works perfectly — fast wake times, zero sleep issues in Windows 11 Final Thoughts: For anyone running a high-end system like mine — especially with power-hungry components like the i9-12900KS and RTX 3090 — this PSU offers peace of mind. No coil whine, no overheating, no second-guessing whether it’s enough. It’s quiet, efficient, and built with headroom for future GPUs thanks to the included 12V-2x6 cable and compliance with the latest standards. Highly recommend if you’re building or upgrading a performance-focused rig and want something that’ll last.
