CORSAIR RM850x Fully Modular ATX Power Supply – 80 PLUS Gold – Low-Noise Fan – Zero RPM – Black

Great PSU replacement for my Lenovo Legion T5 26AMR5
Works great on my Lenovo T5 26AMR5 AMD Ryzen 9 5900x system.TIght fit, remove the PSU bracket and the old PSU and insert and slot it in at an angle with the sata cables connected and connect the mobo, cpu and pcie connectors last after the psu is sloted in place.Powerful and stable and great price.

Good price, easy install, works great
I got this to upgrade my Alienware R11. Fits perfectly, works fine. It comes with a LOT of cables, and not only those, but tie-wraps, wire looms, even color-matched mounting screws. No instructions, but they aren’t necessary. The ATX spec connectors can’t be plugged into the wrong things in general, they’re all keyed differently. My only gripes, the cables of course come in a standard length, too long for any of my connections. But, that’s what the tie-wraps are for. I wish the SATA power cables included some right-angle ones, cover on the R11 is a very tight fit if you have one of the extra disk bays populated. One final thing, there’s a knob on the back of the supply with no description of what it does. Well, it sets the minimum fan speed. In the ‘off’ position, it enables zero-RPM automatic mode, which is what should be used. Otherwise, it sets an always-running minimum speed that can increase automatically.

Unleash Power and Silence: Corsair RM850x (2021) Power Supply Review
I recently purchased the Corsair RM850x (2021) Fully Modular ATX Power Supply, and I must say, I am extremely impressed with its performance and features. Corsair has always been known for delivering high-quality power supplies, and the RM850x is no exception. Here’s my review of this remarkable power supply.First and foremost, the efficiency of the RM850x is outstanding. With its 80 PLUS Gold certification, it delivers excellent power efficiency, ensuring that my system consumes less energy and runs cooler. This not only helps in reducing electricity bills but also contributes to the overall longevity and reliability of my system.The fully modular design of the RM850x is a game-changer. It allows for easy cable management, as I can connect only the cables I need and keep the rest neatly stored away. This not only enhances the aesthetics of my build but also improves airflow within the case. The modular design also makes installation a breeze, as I can effortlessly connect the required cables without any clutter or hassle.One of the standout features of this power supply is its low-noise fan. The fan operates silently under regular loads, and I barely notice its presence. It only kicks in when the system is under heavy load, and even then, the noise levels are impressively low. The Zero RPM fan mode is particularly noteworthy, as it ensures complete silence during idle or low-power usage scenarios. This is a great feature for those who prefer a quiet computing experience.The build quality of the RM850x is top-notch. The unit feels solid and durable, and the black finish gives it a sleek and premium look. The cables provided are of high quality and have a premium feel as well. The power supply comes with all the necessary protections, including over-voltage, under-voltage, over-power, over-temperature, and short-circuit protection, ensuring the safety of my components.In terms of power delivery, the RM850x handles my system with ease. It provides ample power for my high-end components, including a demanding CPU and a high-performance graphics card. The voltage regulation is excellent, and I have not encountered any stability issues or power-related problems since installing this power supply.One minor drawback of the RM850x is its size. It’s a bit larger than some other power supplies on the market, so it might not fit into smaller PC cases. However, in most standard ATX cases, this should not be an issue.Overall, the Corsair RM850x (2021) Fully Modular ATX Power Supply is an exceptional product that delivers on all fronts. Its efficiency, modular design, low-noise fan, and solid build quality make it a reliable choice for any PC enthusiast or gamer. With its impressive performance and thoughtful features, the RM850x is definitely worth the investment for those looking for a high-quality power supply to power their systems.I highly recommend the Corsair RM850x to anyone in need of a powerful, efficient, and silent power supply for their PC build. Corsair has once again raised the bar with this outstanding product.

Don’t pay full price if looking for a modern PSU.
Pros,1. 1000 watts of course.2. It’s an A tier rated on the Cultist Network list.3. It has great protections for power spikes, surges and power outages.4. It’s 100% fully modular.5. Has plenty of cables for almost any device.6. It runs fair quiet and cool.7. I got mine for 60 off.Cons to be fair,1. This is a big unit so make sure your case will support it.2. I found that the way the cable are that cable management isn’t the easiest compared to other PSU I’ve used in the past.3. If you’re looking for a PSU that ATX 3.0 or 3.1 with PCIE 5.0 or 5.1 cable support this PSU would require adapters and fir a lot of people wouldn’t be ideal.4. For as old as it is it’s not worth the regular going price. I got mine on sale for roughly 60 cheaper so that’s worth it to me. If you have to pay more than 140 look somewhere else IMO.

I put this in a brand new build. I like all the cords they give and that it is modular. I didnt need all the cables, so I was able to put them aside for a time when I may need them. No noise, fit well in my tower, and it does everything I would expect from a power supply unit. If it lasts five or more years, I will feel I got my money worth. I have had no problems with it, so as of now, after 6 months of 24/7 use, I am happy and do recommend this product, even though it is pricy.

Muy buena fuente de poder, fácil de instalar y para el gabinete que tengo quedo perfecto en tamaño, cables que se notan de muy buena calidad 10/10, el ruido es poco y casi ni se nota

Work fine
