Review on Corsair RMX Series RM850x 850W 80+ Gold Fully Modular Power Supply (CP-9020180-NA) - Efficient and Reliable Performance for Your PC by Erin Jackson

My old PSU sounds like a tractor under full load so I need a quiet PSU and this one is absolutely silent. The quality looks good and it's easy to install. A few cons: 1. It smells funny, the fan blows air with a plastic smell. It takes several days to disappear.2. The screws are kinda difficult to assemble, but only at the first time.3. If you buy this power supply because of its low noise level, you get what you paid for, but you will find that there are other noisy parts in your computer, such as: B. GPU fan, case fan, CPU cooler, hard drive, etc etc. Finally, you want to replace them all. In short, this power supply spoils the mood. I've only been using it for a few days, so I can't comment on durability. If you're reading this and I haven't complained about the durability, then the PSU is working properly.
