10/10 performance.

My need for this card came about because I finally bought a current GPU that was near the top tier. Previously I had only bought current mid-tier GPUs (3060ti, RX6800) or top tier cards that were 4-years old. All my previous power supplies only had a single PCIe power line that had 2 daisy chains off of it. This worked great - even if I had multiple GPUs. Upon upgrading to a top tier GPU, the computer would hard crash during GPU intensive tasks - meaning it would be unresponsive to power or reset and could only be restarted by cutting off the power at the wall, then turning it back on. It did sound like a PS issue. At first, I went through my current power supplies - going from 500W to 750W to 1200W. But all the same thing. Then I read on the internet that this is common with top tier current gen GPUs (RX7900, RTX4080 or better) when the GPU is being fed off of a single PCIe daisy chained line. All my PSU, including the 1200W only had a single PCIe line daisy chained into 2. I looked for a name brand PS and found this one. I ordered it the thursday before Easter and it arrived in 2-days as promised. Since it's a modular PS, it takes slightly more finesse than just a wired PSU. The connections need to be run to the mobo and devices first, then dangled where the PS will be mounted. Then after putting the PS into position (before screwing it in), the cables needed to be hooked to the PSU, then the PSU screwed in. So far so good. No crashes yet. It's also quieter than all the ones it replaced and they were all known name brands - albeit all at least 2-years old. If it doesn't solve my problem, you can bet I'll be back with an update. Fingers crossed.

Rock-Solid, Whisper-Quiet Power That Just Works The Cooler Master MWE Gold 850 V2 impressed me from the start with its sturdy build and thoughtful design. I used it for a mid-to-high-end gaming and productivity build—Ryzen 9 5900X paired with an RTX 4080—and it has handled everything I’ve thrown at it without a hiccup. Startup is instant, voltage rails stay steady even under heavy GPU load, and fan noise is practically nonexistent unless you’re pushing sustained wattage. Installation was straightforward thanks to the fully modular setup. The flat black cables are flexible and easy to route cleanly, especially in a tight mid-tower case. It comes with two EPS connectors, which is helpful for modern motherboards, and the included power cord and screws mean you can get up and running without hunting for extra parts. Thermals have been excellent; it stays cool to the touch even after hours of gaming. Efficiency is solid—Gold-rated performance with minimal waste heat. It’s a definite upgrade over the older Bronze or semi-modular units I’ve used before. If I had to nitpick, the included cables aren’t sleeved or braided, so they don’t have that premium look some enthusiasts want—but for reliability, silence, and clean power delivery, this PSU hits the sweet spot. Bottom line: A dependable, quiet, and efficient 850-watt modular PSU that’s perfect for modern GPUs and future upgrades—excellent value and performance from Cooler Master.

Se quemó la fuente de poder a los 3 meses de uso jugando Minecraft Bedrock. Quise hacer algún reembolso o algo, pero al ser extranjero la garantía solo duró 30 días. Al final, solo perdí dinero. Historia de lo que pasó al usarla: todo bien. La compré pensando en futuro, para instalar una gráfica 5070, ya que la actual era una 3060 Ti. Quise cambiar la fuente de poder porque tenía una Azza de 650 W Plus Bronze; me decían que era un poco mala y que tuviera cuidado con esa fuente, ya que cuando se daña puede afectar otros componentes y llevarse la gráfica. Ahorre y me compré una supuestamente mejor, la Cooler Master de 850 W. Después de hacer el cambio, todo funcionaba bien. Pasaron 3 meses y casi ni usé la PC; mayormente la utilizaba para ver YouTube o hacer informes de la universidad. Unos amigos me invitaron a jugar Minecraft Bedrock, ya que habían pagado un servidor. Jugué unas 4 horas, me levanté para tomar agua y escuché una explosión. Algo olía a quemado, como plástico quemado, y vi que la PC se había apagado. Al lado estaba la PC de mi pareja, que no sufrió nada y seguía funcionando normal. Mi pareja me dijo: “Creo que explotó la fuente de poder”, molesto porque se supone que era mejor y era nueva. Cuando la desarmó e hizo la revisión, efectivamente había explotado un transistor de la fuente, dañando mi placa madre. Por suerte, mi placa era buena y tenía protecciones; no se llevó la gráfica ni el procesador. Gracias a las protecciones de la placa, solo murieron la fuente de poder y la placa madre.

I got this when it was on sale 850 V2 for $70. It was a very good deal. I really appreciate this seller! I use this with a power hungry 7900X. The PSU itself is not super quiet. It's ok. My last PSU was able to completely turn off fan, this one is always running at like 500-700rpm or something. But at this price, and 850W (849 of which are available on the 12V rail!). Also, it has only 2 EPS connectors, but you can always buy your own later. At my purchase price, it is great value for money. Product came sealed, but in its brand packaging (no outer Amazon box, which is good for the environment, I guess) Update: 1 month later, I still have no problems. I notice the fan is kind of strange. It's not a smooth sound, it's kind of an warbling, like the blade or bearings are unbalanced. It was like this from the start, and has not changed. Also, the fan is supposed to be sucking from the top and blowing out the rear of the case, but if you put your hand over it you can feel it blowing out the top. Very peculiar. It's like the fan "sucks" literally/figuratively. Still, this was an amazing deal, if this lasts 5 years, it gets ⭐️⭐️⭐️⭐️⭐️ from me.

I recently installed the Cooler Master MWE Gold 850 V2 in my desktop build, and overall it’s been a really solid power supply for the price. It hits a sweet spot between performance and efficiency without costing as much as enthusiast-grade models. ⚡ Power & Efficiency This PSU delivers a steady 850 W of clean power — enough to support high-end CPUs and GPUs — and it’s 80 PLUS Gold certified, meaning it operates with very good energy efficiency (around 90 %) especially under typical loads. That helps keep my electricity usage down and reduces heat inside the case. 🔌 Modular Cabling The fully modular design is a big plus — you only connect the cables you need, which makes cable management easier and improves airflow, resulting in a much cleaner build. 🌀 Cooling & Noise It comes with a 120 mm HDB cooling fan that stays relatively quiet during everyday use and even under load. You do notice some noise under really heavy stress, but nothing distracting. 🔒 Built-In Protections This PSU includes protections like over-voltage, over-current, short circuit and over-temperature shutdowns to help protect your components. ⚠️ Things to Consider Some users note that the included PCIe cables can be limited — if you’re planning on powering a high-end GPU that needs multiple PCIe power plugs, you might have to source extra cables. A few builders find the flat modular cables a little stiff to route in tight cases. 💡 Bottom Line: This Cooler Master unit gives you excellent value for an 850 W Gold PSU — efficient, modular, and quiet enough for most gaming and content creation PCs. It’s a reliable choice if you’re building a powerful system without spending top-tier PSU prices.

I learned that my old power supply was notoriously bad, so I figured to go with the Cooler Master. So far, it's been perfect. There's never been any problems like with my old one. The quality seems to be great and if you're able to read a bunch of guides online, it's somewhat straight forward to install. Just make sure to label all of the cords that you're dealing with. It's more than enough for all of the games I've been playing so I'd definitely recommend this.

Came with American power cable

Excelente fuente de poder!! Se me fue la luz varias veces, ha subido y bajado la luz, ha habido intermitencias y no he tenido problemas con ninguno de mis componentes

I am extremely impressed with this product! It arrived quickly, was exactly as described, and works perfectly. The quality is outstanding, and it has made a noticeable difference in my daily use.

It looks like it has been tampered with. Missing two cables. A small plastic bag was opened

Works great
