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.
