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

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.

Didnt have well mounting, so off to thw welders to built shelve.

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.

The quality of this power supply speaks for itself, great product, a must have!!!

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

I had to connected PS Fan to internal 5 Volt source...and now it is OK.

Would buy again! Great product!

easy install

Llevo ya 3 semanas con la fuente trabajando a diario con una RTX 3060 ti y todo a funcionado según lo esperado. Buena presentación, el envío llegó a tiempo y la fuente cumple con los mencionado. Gran producto!

Power supply was easy to install. Works perfectly in a new build. Feels sturdy and well built. Not much else to say.
