Corsair RM850x 850W 80+ Modular Power Supply

You’ll most likely be getting the newer 2024 model, not the older 2018 version, so it’s worth checking other RM850x listings, you’ll find it priced more competitively there. This particular listing should be updated to avoid confusion, since the older model is no longer being produced or sold. That said, the RM850x is an excellent PSU: reliable, efficient, & quiet. It’s just not worth paying an inflated price here when you can purchase the same unit for less elsewhere.

Corsair isn't what I'd call an old school PSU vendor, but damn have they ever proven they're here to stay. My favourite PSUs back in the day were OCZ and PC Power & Cooling. They were my go-to vendors but sadly neither exists anymore the way they used to. Since then I've been using Corsair PSUs and I couldn't be happier with their performance. I have a Corsair HX850 as my original modular PSU, so when I went to build my new PC I picked up this RM850x model. It's fully modular, it's whisper quiet, it isn't too long, and it has all of the connections you could want. But what sets this unit apart is that it comes with TWO CPU connectors! So you can hook it up to a motherboard with an 8pin and 4pin connector for the CPU. If you're doing any serious overclocking with an i9 or Ryzen 3900+ this is absolutely the PSU for you. The only thing I don't like is how the connectors have this extremely stiff wrap near the actual plug ends. While you can still do a clean cable build in a case, these stupid stiff wraps will prevent you from being able to twist or curl the cables so that they aren't sticking straight to the side for a couple inches before going back to being a regular cable. Why they chose these stupid wraps I'll never be able to guess, but they unfortunately exist. If you're using the stock cables this unit is a 9/10, with the point loss for those ridiculous stiff wraps. But if you're going to use cable extensions or aftermarket cables then this unit is easily a full 10/10.

The product is fine, but do not purchase from this item from GREZ LLC, they will charge you more than double the average price and their returns service is the worst I've ever experienced.

Muy buena fuente de alimentación. Tuve que cambiar de una RM650x a esta porque mi nueva tarjeta madre requería dos entras de 12V (Aorus Master). No ha producido casi nada de ruido y el ventilador se detiene por completo cuando la carga es suficientemente baja. Los cables son de muy buena calidad. Mi única queja es que los conectores podrían tener un mejor sistema de anclaje (entre ellos cuando se pueden dividir) y las terminaciones tienen un forro de plástico poco flexible que hace el acomodo y manejo de cableado un poco difícil. Sin duda es una buena solución a fuentes de alimentación y tiene una alta eficiencia.

Es un buen producto llego sellado y protegido en excelentes condiciones, necesitaba una fuente de poder que diera voltajes estables ademas de que estuviera sobrada para futuras actualizaciones y esta es buena opción. Hasta el momento no ha fallado y el ruido se su ventilador es casi nulo ademas de que no se enciende mientras no sea necesario. El que sea completamente modular me ayudo a ahorrar espacio, los cables se sienten duraderos y son negros completamente dando un aspecto mas limpio. En caso de que me falle o tenga algún inconveniente modificare mi reseña
