Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (Low Noise, Zero RPM Fan Mode, 105°C Capacitors, Fully Modular Cables, Compact Size) Black

Havent had any issues (Almost 1 year later) powering my i7 9700k, overclocked, and have no stutters or power flaws.

The quality seems really good for what i payed and feels very worth it.

Would buy again! Great product!

This power supply is fantastic. It is a little long, however, and may cause an issue if you dont have the space in your case for it. good price! Arrived quickly.

Works perfect. Great price and better warranty than my 1200X that went out all the sudden. I could have had a new one if I had kept my receipt for warranty. So, that was my fault. This time, I have my Amazon receipt right here. Corsair did try to help me locate the receipt for the old one. But this one is working so perfect. I think I like it better.

First of all none of these PSU manufacturers make it clear you have to use THEIR cables otherwise it wont even power up. This can be very frustrating if you did a good job running your cables. My advice is always use extensions on a build. This way replacing a PSU doesnt require rewiring the whole thing.

Si eres como yo que tiene una PC con bastantes accesorios, GPU y CPU demandante en cuanto a energía y quieres irte a la segura, esta es la mejor opción en cuando a relación precio. Ya había tenido una mala experiencia con una Corsair CX750 pero con esto todo cambio. El diseño modular de la fuente hace que sea muy sencillo conectar justo lo que necesitas, aun que los cables SATA pueden ser un poco cortos si tienes un case grande y los discos duros no están juntos.

This PSU was on sale when I ordered it. I had to contact Amazon support no less than 4 TIMES because it did not ship out to me on time and the shipping date kept slipping. It took 27 days from ordering to having it in my hands, imagine if I needed it in a hurry? The off shore support were mostly polite but completely ineffectual because they are not empowered to actually help. All they seem able to do is provide comfort that it willl ship soon, increase shipping speed (no help when it hasnt shipped), and continually suggest that I cancel my order to relieve their burden. They do not seem to have any way to interface with the warehouses that actually handle orders. It was niceto get a small credit for my trouble that can only be used for items sold and shipped by Amazon (Im not sure how to claim it), but this was an incredibly poor experience buying from Amazon.

This unit seemed to work fine for a couple weeks. I installed it along with my new GPU, but then had to leave for a trip for about four weeks. When I got back, despite having changed nothing, my PC started randomly crashing -- what was clearly a power-related hardware problem. GPU and CPU werent overheating. Cables were all secure. Windows event log had no errors recorded. Crashing would happen at random times in random scenarios, sometimes 20 mins after boot, sometimes 6 hours. Well, what can I even do? Buy a new power supply and see if the issues persist. Spoiler: they didnt.
