CORSAIR RM850x Fully Modular Low-Noise ATX Power Supply – ATX 3.1 Compliant – PCIe 5.1 Support – Cybenetics Gold Efficiency – Native 12V-2x6 Connector – Black

Corsair siempre sacando pecho de su calidad y productos.

For as long as I've been building my own computers - more than twenty-five years now - I've used Corsair power supplies. I don't necessarily think they are better than any other brand, but they've never let me down, despite all my computers generally running 24/7 in dusty, sometimes humid, sometimes 90F environments. I purchased this not because my old Corsair supply failed, but because I was installing a 5070Ti and wanted higher output as a result - the 650W would have barely been suitable. Swapping supplies was dead simple; the old one slotted in place of my old RM650x, and all I needed to do is replace the old power cable from the RX470 with the newer 12V-2x6pin. I have all Cablemod Sleeved cables and debated replacing the the new 12-pin connector with a sleeved variant, but it's so flexible and clean looking I decided the Corsair one was just fine. I've been running for about three months now without any issue. Obviously not much time on a PSU but I doubt I'll have problems. As an aside, this one has a variable fan speed knob. So far as I can tell, if you leave it off it will just run in normal, automatic mode, whereas if you use the knob it will instead always run at a certain speed. I think, I'm not totally clear on it. I just keep the knob off - my system is already very quiet and I don't think I've ever heard the PSU fan turn on even with my old supply, much less this newer one. As my mobo doesn't support PCIe 5.1, I can't comment on that part of the component. I would definitely recommend this RM850x, and would recommend Corsair in general, so far as PSUs are concerned. They seem very solid and well-made, and I've never been disappointed by them in the past.

If you’re building a high-end rig and eyeing a power-hungry GPU like the RTX 5080, the Corsair RM850x has your back. I paired it with my RTX 5080 build and it runs buttery smooth—zero stability issues, zero noise drama. Pros: • Handles RTX 5080 Without Breaking a Sweat: Delivers clean, consistent power under load. • Fully Modular Design: Only use the cables you need—clean, simple, and airflow-friendly. • Whisper Quiet: The fan barely runs, and when it does, it’s silent. • 80+ Gold Certified: Efficient and cool, even during long gaming sessions. • Top-Notch Build Quality: Premium components and a 10-year warranty for peace of mind. Cons: • Cables Are a Bit Stiff: Cable management takes some effort, especially with the 24-pin. • Slightly Pricey: But you’re paying for reliability and long-term performance. In short, the RM850x is a future-proof beast. If you’re throwing in a next-gen GPU like the RTX 5080, this PSU is more than ready to carry the load.

Bought this 850 watt unit 6 months ago and just now last week installed it. Everything went smooth, my son did most of it, no problems with cables or routing or anything. I love the feature of being able to control the fan speed. This is a well built, well known PSU. It is performing as expected, which is quiet, cool and stable. Highly recommend this unit from Corsair.
