It does its job and provides power to my PC components with a fantastic gold efficiency rating. This version is also smaller than Corsair's previous 1000 watt PSU, but have had no troubles of overheating at all. The fan control knob is also a nice feature to have if you really want to control the speed of your PSU fan. Cables are also easy to connect and disconnect with no problems at all and the dedicated 12v-2x6 port is great to have since it lessens the amount of cables needing to connect to your PSU.

I recently installed the CORSAIR RM750x Fully Modular ATX Power Supply in my gaming machine, and I have to say, I’m pretty impressed. First off, the fully modular design is a game-changer – no more cables cluttering up my case. I only used the cables I needed, making cable management a breeze.The 750W is more than enough to power my setup, and it runs super quietly – I barely hear a thing, even during intense gaming sessions. It’s also got plenty of headroom for future upgrades, which is great.Overall, the RM750x feels like a top-tier power supply – solid, reliable, and built to handle the demands of a high-performance gaming machine. If you're building a gaming rig and want something that won’t disappoint, this is the one to go for. Just plug it in, sit back, and let the power flow

This has been a solid power supply for my first build. Powering a Ryzen 9700X and Radeon 7800XT, everything has been great. The modular design made building quite a bit easier, although there is a considerable lack of documentation. I had to piece together what cables go where from online tutorials and the words "PCIe" and "CPU" on the component-end of the cables. Otherwise, the cables are solid feeling, if a little stiff.

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.

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.

Easy to install, quiet. Overpowered for the system, but may be okay if I ever install a big graphics card. Very happy so far. FWIW, use the cables that come with the power supply. I tried using some of the cables from the previous PSU and something didn't work right. Feels robust, and plenty of power.

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.

Well made needed for high powered gpu solid

Una excelente GPU, soporta 4080/90 y procesadores de alta gama, protege del fenómeno "dirty electricity" y proporciona estabilidad a los componentes de la pc, por algo se sigue vendiendo tan bien a pesar de ser un modelo con unos años, importante combinarla con un ups/no break.

My biggest complaints with Corsair power supplies for the longest time was the cables. They were always super thick, especially the 24 pin cable. Luckily with this refresh, they've made all of those cables incredibly thin and flexible, making them easy to work with and more aesthetically pleasing as well. They even come with cable combs, although I wish there were more. For example there is only one 24 pin cable comb. And while these cables won't beat the quality of custom cables even from cheaper brands like AsiaHorse, they are still better than what you can find from most power supplies.

La fuente perfecta para 2025 con el conector para las tarjetas serie RTX 40 y 50 de Nvidia, es muy silenciosa y con suficiente poder para un equipo de gama alta, además los cables son mallados lo que le da una estética limpia e incluye los peines para los cables y dejarlos visiblemente ordenados, la recomiendo si la encuentran a buen precio

Great psu and seems to run very quiet under heavy loads. Very happy with this purchase! Would recommend 👌
