Review: Super strong and quiet. - This comes with all the cables needed and more. It’s a quality power supply and Corsair stands behind them 100%. I had an issue with an older one in another PC and the RMA’d it back and sent out a replacement without a hassle. This one went into my sons gaming OV and has been running perfectly for months now. I bet it outlives the motherboard and processor. Great buy.
Review: Efficient, quiet, and more than enough. - This power supply is probably overkill for me but I wanted a power supply that was completely silent and that will last me through any future upgrade. I never reach loads high enough with the components in my system that the power supply's fan will even spin up and create unwanted noise like my last one. This is one of the highest rated efficient power supplies out there when I bought it, besides the RM1000x, of course. The price seems to fluctuate and balloon ridiculously high often with each of these models. I bought this at around $100, and when I posted this it is up to $150. The RM100x I have seen at $120, now it is somewhere around $175. I can only assume this is because they are in such high demand because of their 'legendary' efficiency ratings by some guy with a website I forgot its name that does all of the testing on power supplies... anyway. It is powering the following and the the fan never spins up besides at boot: AMD Ryzen 1700 OC'ed to 3.9 GHz Asus Prime B350-Plus Nvidia GeForce GTX 970 Corsair 3000MHz RAM 2x 8 GB Corsair H100i v2 1 SSD 3 HDD It will run your stuff and it is super quiet.

### ⭐⭐⭐⭐⭐ I previously owned the extremely nice version of the corsair psu i think the ax860i
*by D***H on May 27, 2016*

im not building my new computer till mid june (when gtx 1070 comes out) but i couldnt pass up on the 110 dollar sale, ive done alot of research on psu's so im posting this review early just to inform people. I previously owned the extremely nice version of the corsair psu i think the ax860i, but ever since i installed this and a new gpu my computer has been having issues, i couldnt ever find out if its due to the psu but after doing a bunch of searching i found out that the ax one i had was the very first iteration of incorporating digital feed back in a psu - im here to tell you thats not needed, which is why i didnt go with the rm (digital one forgot exactly which it is) - basically it says that if a product doesnt need that much power it wont send it the power (this one on the other hand is completely analog (right term?) and it will send a constant power signal to all you products with no fluctuation - if you plan on upgrading soon, unless u do this for ur business and/or have a multimeter for measuring wattage, i would 100% say go with a non digital psu - i love the quality control and customer service and all corsair products ive owned in the past so it was a no brainer to chose from corsair - ive always liked over buyign for future builds too and this one should do it, everything is taking less power these days so even if i had to run a 1070 in sli i could ( i never will though im a believer in a single gpu), i did want all moddular....so this one took the cake, oh and a manufacture date from 2016 is always nice (product released like a month ago) as i said i havent used it yet but i have the ax860i so i suspect this will work with flying colors as all corsair products do sorry for the garbled typing but i wanted to record my thoughts as i was thinking about this
