Product Description

Size Name: 860W | Style Name: Standard

Product Description

The fully modular cable set lets you use only the cables you need. You can install the AX Series first and then add cables one-by-one without having to deal with the dreaded “cable octopus“

AX860 delivers up to 92% energey efficiency under real-world load conditions. Better efficiency means lower energy usage, less excess heat, and lower operating costs. Since less heat is generated, the fan doesn’t have to work as hard, so there’s less noise, too. It’s a great choice for smart, efficient power delivery.

All of the power cables have connectors on both ends, with nothing hard-wired to the PSU. This makes for easier installs (you don’t need to deal with an octopus of cables while you’re putting in the power supply), and you can add cables one-by-one, using only the cables you need. The result is a cleaner-looking build, with better airflow.

High-quality capacitors, a dedicated single +12V rail and a PF value of 0.99 give you reliable power output with extremely low ripple and noise. • Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components. And, AX860 is engineered to meet maximum power output at a server-grade 50° C temperature rating. Compatible with 4th generation Intel® Core™ series processors

Sure it was a lot of money (I paid £133) but for the 92% efficiency it provides, the 7 year warranty and connections / power available to hook up 3 graphics cards + 12 sata hard drives, it's a bargain.

I currently have it in an i5 2500k, AMD 7970 3GB rig with 4 HD's and on idle, this PSU draws between 115-120w.

Gaming wise, the average is 150-180w, the most i could get it to consume was 290w playing Metro 2033 at maximum direct x 11 settings.

Considering the fan on this doesn't turn on until you hit the 380w mark, this PSU should stay silent for any single graphics card setup.

With the wattage i'm consuming, i could easily have 2 decent graphics cards in my rig and this PSU wouldn't break a sweat.

Bargain!

What can i say i was very uneasy buying this power supply as lot of cosair power supply's have had a bad coil whine. I have looked on other sites and it seems to be an issue for all companies. So i must say the delivery on this was on the mark and better thank you>
As soon as i got this i thought wow its small, i have an old coolermaster 1000w psu and that was 1/4 bigger.
I just had to plug it in and swopped my old psu for this one. My specs are 2600k 4.6 ghz watercooled ssd drive + 2x wd black drives and a gtx680 not to mention all the fans and other stuff.
I started the pc and for a second i thought it haddent sarted as it was so quiet and strange that the fan never started on the power supply.
When it booted to descktop i just had to overclock up my card for a quick benchmark i got the card to 1200 on the gpu and some on the memory with out any problmes and the fan still never kicked in on the powersupply i flicked the switch to normal mode to make sure the fan did work.I must say it was spinning but i still couldnt hear anything.
It looked like the company that i bought it from had tested the powersupply and then re-sealed it very carefully for which i am very greatfull becuase there is nothing worse than getting a dead powersupply and having to send it back. My only gripe with this one is that the sata power cables are very stiff to put in the hadrives.
Yes the 6 pin motherboard cable will fit around the back of my haf 932 but for cable manament i will need an extension lead there is nothing wrong in buying an extension cable and sleaving to match the rest (you cant get a power supply to complettly fit every case)

Unfortunately, I did get a defective unit on my first try. But Amazon was great about returning it. The other that I bought is running very well. The fan hardly ever runs as it only turns on above a certain temperature. When it does run it is nearly silent. If the Corsair link software it to be believed, the unit is incredibly efficient, with extended periods at 99% efficiency. The Link software is great for controlling current usage on the PCIE slots and total wattage among other things.

Very satisfied with this power supply the hybrid mode means the fan dose not even turn on.
the wires for the psu are also all black along with the sheathing making it very stealthy

Style Name: DigitalSize Name: 760W Verified Purchase
This is a great PSU. I bought this for a small server and it is extremely efficient and silent.

The "i" model comes with a USB dongle to allow monitoring of the PSU. It connects between a special socket on the PSU and an internal USB header on the motherboard. Software then provides real-time info on the PSU performance.

The problem? Well the software constantly polls the hard drives and this prevents them from spinning down. For a very energy efficient system as is possible with this PSU, this is an unforgivable oversight. I ended up by uninstalling the software and disconnecting the dongle. The PSU works fine without it.

I would recommend purchasing the Corsair AX760 PSU instead of the AX760i. It's the same power supply but without the dongle connection and problem software. You also save about 30 pounds, get a quieter system and save even more electricity.

In terms of Aesthetics the AX860i looks pronounced with its dark and orange logo design. For this is a rather strapping PSU and will fit virtually any chassis but it's wise to always make sure you have the right chassis for this PSU.

The cables are done in a dark black. The connectors themselves are all black as well. The added benefit obviously is very clean looking wiring for that ultimate finish in your ATX case. I am a complete novice, but in my ever so humble opinion the Modular design is the way to go. As you use what you need in terms of wiring, keeping the innards clean and tidy, plain and simple. And overall it is a great looking PSU, slightly longer than your typical ATX sized PSU though.
This PSU is very efficient, has good looks, it is modular, it is stable, and comes with all dark cabling and its drop dead silent as well. The one thing that could hold you back, from your potential purchase, is the pricing. But please bear in mind The 7 year warranty and after all it's a premium product - that is robust and well made.

The new AX series PSUs stand out from many competitors by a good margin. But admittedly it's a crowded market place - with class and proficiency levels being bumped up year on year. Again remember this PSU is highly efficient, it has a Digital Signal Processor (DSP) to provide digitally-controlled power and an interface to Corsair Link software for real-time monitoring and control. This AX860i PSU is truly an impressive piece of kit.
