    Una de las mejores fuentes que he utilizado , lo.unico que recomendaría es una mejor disposición en el etiquetado de los cables , al ser modular es un poco complejo identificar donde va cada cable si no se tiene experiencia

    I love this power supply unit; it has been chugging along for just about 4 years. Ive never had a single problem with this PSU; it powers everything I have ever had installed to my PC without fail, and most likely has much more power I could utilize. Any negative reviews are just a PSU lottery, in which the users received defective units. I feel bad for them, especially those whose PCs were fried due to a defective unit; however, even if I had problems, I would still not damn Corsair, and say things like dont buy from Corsair, their products suck. I have even had a couple of their computer cases, a few of their AIOs, RAM chips, and have never really had any issues. The one time I had an issue with one of their AIOs, it was due to my lack of knowledge of water cooling units, and their customer support was very good about it.

    Can’t believe it fit in his stock ASUS chassis, but it’s amazing, great price too!

    Sata cables are only useful if you have drives stacked on top each other and enough space to fold the extra length. If your drives are placed vertically like most high-end cases do now, you need to get an extension to make it more manageable.

    I bought the RM850 to replace a Zalman 1000w that died (after 12 years!) during a black out. It was easy to install and it works great, zero problems. I especially liked the completely modular cabling. Nothing comes out of the unit. All cables plug in, so no extra dangling cables inside the case. Also the dual 8-pin PCI-e cables feed into the graphics card with only one cable coming out of the PSU, as you can see in the picture. Great cabling throughout!

    When I bought this it was super cheap for some reason. I thought it was sketchy but bought it anyway. If you can find this on sale buy it. I got mine for around 90 bucks. It was an incredible price at the time. Its not junkie or sketchy its really good tbh. Buy it!
