- So much power! - fan turns off when it doesn't need to cool off - 7 year warranty - Corsair is #1 in the game for PSU's. - Tons of connectors

- Price is a little steep. But you get what you pay for.


Upgraded to this from my Hx1000 that I had for 7 years. Got rid of it because of an annoying fan noise it would make time to time. I couldn't be happier with my purchase. I only buy corsair power supplys. If your in the market for a new PSU. I would honestly pick this one!

Energy Efficient Quality Product, modular, more than enough power for SLI and Crossfire.

Corsairs rebate process is terrible if you apply for rebate.


Great power supply, and NCIX was awesome at helping my rebate problems with the corsair rep. If you apply for a rebate on this product, you should know that corsairs rebates can have issues. Check out the ncix forums to read more.

Quiet, Efficient, Loads of Power Options

None that I can think of


This beast of a power supply has served me well this past 6 months, purchased along with a 900D for a custom loop setup and might I say, wow..this unit provides a surplus of connection options all while keeping whipper silent. Fan only spins up when i boot my pc for a total of about 5-10 seconds, after which it stops and sits idle as I'm not stressing it by any means. Very happy once again with Corsair products and will definitely be sticking to my guns next time around. Corsair you have done it again and have kept me on as a loyal customer.

Lots of power. Sleever friendly.



If you are running more than 1 gpu and want a top quality unit can't go wrong with this. An extra bonus is there is very minimal double wires if you want to sleeve this yourself.

Extremely capable and efficient.



This PSU is much better than the Antec Quattro 1200 watt unit it was replacing. It is quieter, more power efficient, and fully modular which really makes for easy and tidy cable mangement. Still running strong after 2 years, and worth every penny.

Always runs 93% efficient and up. I have an overclocked 920 u 3.8, 200 blck, and 2x gtx 680 lightnings with all the usual hardware. The Fan never turns on, even when stress testing to the max. Never runs above 50 Degrees C Max. Really cool to get a real time monitor of how much power is being drawn from the socket and how much is being converted to usable power to the system, as well

If the fan is turned on manually above 40 Degrees, its a bit loud...though I see no reason to do so. Initial software setup was a bit annoying since the application first had a hard time detecting the Link Dongle. After a few restarts and software setup though everything runs silky. Last CON is that although the cables are protected with a very dense wire cover, they seem a bit cheap. My cables fro my recently blown (5 year old) thermaltake 1200W had very nice shielding, color code, and obvious quality overall for cables.


I never go to over 800 Watts with my system. If you run a similar system or less, def stick with the AX860i, much better deal for what you need and what you get. I only got a 1200 because I plan to run my next setup from this PSU which will include a high power water pump, a few more fans, a couple more drives and some extra usb peripherals.

Efficient, all black cables, quiet, clean power

Cable length, coil-whine, price


SATA and 8-pin are too short for my 800D, so a word of caution to anyone planning to use this PSU in a full tower case, where as the 24-pin is quite long... Got an RMA for my first 1200i for severe coil-whine, replacement has some intermittent coil-whine, but I wont be bothered to replace this PSU a second time. Some videos on Youtube and posts on Toms seem to suggest that this is not an uncommon problem. Otherwise a good 1200W PSU (especially if you plan to use the included cables indefinitely) If you plan on using custom sleeved cables, etc. i would suggest something from xfx or silverstone at a lower price point, and with cable length designed for a full tower chassis (I ended up fabricating new 8-pins to make the 1200i work)

Excellent power supply, 1200W of power at high efficiency. Fully modular, 7 year warranty. There's nothing else you can ask for.

Great psu for the user who would like to do a extreme build. just that it is pricy compared to other good units from seasonic and xfx

Stellar performance and reviews.

Pricey but hopefully this PSU will be ultra reliable in the long term.


I contacted Corsair Tech Support at regarding the adapters that ALAIN_L referred to in his Customer Review dated 09/14/12. Corsair promptly replied stating, "I told you I was unsure if we had these adapters and you told me about what this user posted. I have checked with our parts department and we do not have these adapters. I'm not sure why this user posted this." So what's up ALAIN_L? I
