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

Most of the time, the fan doesnt even run, so thats as quiet as you can get. Even when it runs, its not loud, so I really like that in my desktop PC. The price was good, and I like the modular cable design. Plus, its a Corsair, so Im expecting it to last.

IT HUMS .... and it cost me $124

The power supply arrived beautifully packaged, on time, and looking perfect. It was easy to install and made absolutely no sound - or output voltages. When I contacted Amazon for an exchange, they said they were out of stock and recommended contacting Corsair directly. When I explained the situation, the first customer service rep at Corsair was very sympathetic and helpful and quickly offered to generate an RMA and exchange the PSU. Then nothing happened. I contacted Corsair again and the next rep said that since I bought the PSU through Amazon, I should handle the issue with them. So I returned the PSU for a refund and got a different one. Then, almost a week later, the second Corsair rep emailed saying that since Amazon was out of stock (which I had established on the first call), Corsair would exchange the PSU. Of course, by this time the Corsair PSU had been returned and the other PSU was on the way. The other PSU arrived, was installed, and is working fine. The best thing about this whole process is how well the Amazon return process worked. It was simple and quick.

When I received the package, I opened it and it smelled like as of it was burned, terrible smell, but than I took the risk of plugging in psu and its not working, faulty product, avoid getting scammed, ordered it all the way from USA to middle east paid so much and I get a faulty psu.

Excelente opción, es silenciosa y al ser modular es perfecta para conectar diferentes componentes.

Good!

Great quality and lots of cables. Very quiet.

Excellent

I really don’t have any mechanical issues with Corsair PSU’s (I have an HX1000 and RM750x) but the cables are so stiff it’s unreal. It’s a hassle to bend the ends to connect to your motherboard to route your cables out of sight. Please use more flexible cables or it would be cool to include a flexible extension. Ultimately they do work well, just a bit hard to bend and route the cables.

First one was dead on arrival, replaced it, and that one is dead as well. I tried troubleshooting everything possible which took time since I had too order a bunch of new parts to do all the testing. Ended up taking it to a brick & Mortar computer store and yup the second power supply is also dead. Two in a row. Real pain. And now my return window has closed. I absolutely do not recommend this power supply unit.
