Description

The Corsair RMX 550W Power Supply is a remarkable power supply you won't regret buying. Offering tight voltage control, efficiency, and quiet operation, it's all you can ask for in a power supply. Modular cables make it easy to manage your cables whether you have a small or large case, not to mention making your computer look professional. With the 80PLUS Gold certification, the 135mm fan on the unit can turn off while the computer is on idle or is experiencing small to medium loads. This is because the PSU works more efficiently and less heat needs to be dissipated compared to the vast majority of power supplies on the market.

EXCELLENT
Works like a dream
By Jack Barnaby
Nearly perfect
Pros:- *7 year warranty* this cannot be overstated- fully modular with sleeved cabling for the main power cables, and flat (albeit slightly stiff) accessory cables- 100% japanese capacitors which equates to rock solid stable power at lower temperatures at all times.- a fan that even at 100% load is practically silent- floppy connector that is an adapter rather than being permanently attached. I'm soo happy this is becoming a thing.Cons:- it's not worth removing a star over, but the length is 160mm, which is standard atx length. I'd really like to see future models in this wattage range move down to 140mm or lower to allow more space in itx builds.- retail price is a bit high, but between sales and rebates that seem to constantly be going on with corsair, this should never really be an issue.Other thoughts:honestly, there isn't much to discuss here. The fan doesn't even turn on until 40% load, and still only hits 22db at 100% load (a whispering conversation is generally rated at about 30db, for comparison, and 20db is half that). You're very likely to have a louder fan for some other component in your case already, so you'll probably never hear this fan at all.In regards to power and efficiency, the rmx (replacing the rm line) are some of the best corsair has ever produced. Jonnyguru gave the 1000 watt model a perfect score, and the 750 model a 9.8/10.It should be noted that this is rated 80 plus gold at 50c (80 plus testing is done at room temperature [23c], so gaming temps really aren't properly taken into account during the certification process) where a corsair cs class psu is only rated to 80 plus bronze at 30c. In a real life scenario where you'll be gaming for extended periods of time (where a case can get up to 60+c), the rmx psu will be vastly more efficient, and generate less heat.

Excellent psu for midrange build
Bought this for a medium/high end gaming build. Appears to be a very good quality psu. Fan doesn't spin at lower loads. No coil whine at high loads. Modular cables are easy to install and have plenty of length for most cases. Corsair warranty and support has always been good to me in case something happens down the road.

Best power supply
Works great and runs my gtx1070 with no problems. It was easy to install and all wires were wrapped in black.
By Vico Paas
(rm550x) very nice power supply
(rm550x) very nice power supply. Although it's a bit on the pricey side for its wattage category, it's very high quality and fully modular, which is a great thing. It's very quiet.

Runs my single gpu setup nicely. No sound that i can hear from the fan. Perfect.
By Randy Reyes
Nice power supply
Verry nice power supply, all the cables included are braided which is a plus. The fully modular setup is great because if you ever need to add anything, all you have to do is plug in what you need. The quality of the power switch seems verry good. When switching it on or off the button does not feel sloppy or loose. It takes a good amount of pressure to click which i like because it feels like a quality switch. I was as well verry pleased with the packaging, the supply itself comes in a mesh bag, and all the cables come in a pouch. Overall i would recomend this product!
