Review: Handles My i9-12900KS + RTX 3090 Rig Without Breaking a Sweat - 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.
Review: Good PSU! - 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!

### ⭐⭐⭐⭐⭐ Stable, reliable, quality power supply
*by A***F on January 28, 2026*

Been using Corsair for my PSU needs for years. None have let me down and this one is looking to continue that trend. Absolutely stable power delivery. Cables are high quality. Powering my 9800x3d and 5080 setup flawlessly since October 2025 now. Absolutely zero noise either from internals or the fan. Came with all cables I could possibly need. Cable length and flexibility are fantastic making them easy to manage.
