Pros: This PSU greats great reviews from sites I trust.

Cons: Worked for only 6 hours before it died. Luckily it didn't damage anything when it went. Just shut off, and after going through the self test procedure with phone support, it was confirmed dead. These things happen, and if it ended there I might still have rated this 4 stars, but... I received this PSU on 10/17, it worked, then died, I called phone support, they confirmed and sent me to the website to start the RMA, and ended the call. Here's where the problem starts. This model isn't list on the RMA form, and it's not listed on the support ticket form. The RMA process was started using a different model and the correct model was annotated in the ticket notes. After 4 days of exchanging emails I was told I needed to call support to setup the RMA!? A call to phone support and I was told they couldn't process the RMA, and I should call back in the 3 days! I called back, RMA was processed. After a week I called to get the status and was told it never shipped, but it would go out 'today', and to call back tomorrow for tracking info. Called next day, and was told the AX860i RMA backlog is 1 month deep, and they nicely upgraded the RMA to an AX1200i, which I later found out also has a 1 month backlog! So finally they downgraded me to a AX1200 (non-I)

Overall Review: I speculate that this PSU has an extremely high failure rate, RMA backlog is out to 12/5/13 - that's 50 days! I was stuck with the choice of a non-functional computer for 50 days or an older, discontinued PSU that Corsair had on the shelf. Either way equals dissatisfied customer, and I'm doubly so for messing around with customer service for 3 weeks before I even got that choice! Now I have a PSU I don't want rebuilt to who knows what level of quality. Corsair, if you're listening ticket # 6192574 . Most of the people I spoke to didn't update the ticket, and in future calls no one seemed to know what was going on. I'm not getting anywhere with CS, and I don't have another avenue available. 1 star the product, 1 star for the service.

Pros: + Incredible Efficiency + PFC on a full digital platform + Excellent Ripple Suppression + Quiet FDB Fan, can set speed in Link software + Corsair Link Software works well + 10 Year Warranty

Cons: - Cable quality is poor. The sleeving is cheap feeling nylon that snags and frays easily. Many cables came out of the box with frayed sleeving where they were bent for packaging. - Not enough PCIe Cables for a PSU this size (8) - The dual PCIe cables are almost impossible to use on graphics cards. The second 6+2 pin connector cable is too short and has what looks like 2 sets of capacitors in the short cable that make bending it difficult. Bending it back to fit a graphics card is just barely possible, feels like it's going to break. Poorly implemented. - Puts out a lot of EMI

Overall Review: Manufactured by Flextronics, they did a great job on the PSU itself, while cutting corners on the cables. This is currently one of the most efficient PSU's money can buy.

Pros: I've been using this PSU for about week at the time this was written. Going by the Corsair Link software, I see I'm running at about 99% efficiency at idle, and using 68 watts. I don't have dual monitors, so I can't watch the statistics in real time while playing a game. But that's next on my list. I'm running the software in Windows 7 Home.

Cons: It took several restarts before the Corsair Link software detect the PSU. Not sure what's up with that, but oh well. It's working now.

Overall Review: No one has bothered to do this yet, so I'd thought I'd list all the cable lengths in my review. It's a safe gamble that this will work in the largest of cases, but better safe than sorry. I'm surprised that Corsair didn't list this in the specs on their product page. I put this in a Corsair 600T case and didn't have any issues with length. 8 pin CPU - 27in (X2) 24pin MB - 25in SATA - 28.5in and 16.5in to the first plug (X2) SATA - 34in and 22.5 to the first plug (X1) 6+2pin PCI-E single - 25in (X2) 6+2pin PCI-E dual - 25in + 6in (X2) Molex - 31in and 18.5in to the first plug (X2)

Pros: Stable power delivery.

Cons: Purchased back in July 2016. Dead in July 2017. First it started off by randomly shutting off and I had to unplug from my APC to get it powered back on, then it just completely died while troubleshooting. For $399 I was expecting better. Mine doesn't seem like a fluke either, its a very common problem with these units. Corsair already has the unit and I'm in the middle of the RMA process. So far their Customer Service has been good but I'm not here rating their Customer Service. I'm rating the AX1200i and if 0/5 was an option, that's what it should get.

Pros: None

Cons: Very Expensive Brick Does not work Horrible RMA process

Overall Review: I have been a Corsair customer for years, buying multiple PSUs and peripherals from the company. So when I decided to build a new computer in March, I picked a Corsair AX1200i for the PSU. Other components included Asus Maximus IX Code motherboard, Intel I7 7700K, Asus Strix 1080ti, Kraken X62, Gskill Trident Ram and Samsung Evo 960 M.2 1TB NVMe drive. The 1200 was a lot more power than I needed, but I wanted to leave room for expansion in the future and I was a fan of Corsair products. I didn't actually complete the build until April, and the system worked fine for a month. Then the system started crashing randomly and frequently. The system would completely lose power, shut off, and then start the reboot process. After trouble shooting everything else in the computer, I disconnected the PSU and then reconnected all of the various cables to the components in the system. This seemed to fix the problem for another month until now. I went to power up the system, and the power button did not do anything. I then checked in the case and the LED on the PSU was red. I called the telephone number listed in the manual in an attempt to contact customer support, and was greeted by a busy signal. I then found a second customer support number online and was finally able to contact Corsair support. They told me what I expected: the PSU was faulty and needed to be replaced. I wasn't very happy about having to RMA such an expensive and supposedly top of the line PSU after 2 months of use. This got worse when I tried to "Express RMA" the PSU. For Express RMA, Corsair puts a hold on your credit card for the cost of the PSU, ships you a new PSU immediately, and releases the hold once they receive the original PSU in the mail. However, the customer support representative informed me that they did not have any AX1200i PSUs in stock. Not only that, they did not have any comparable PSUs in stock and she could not tell me when they would have any PSUs manufactured and available. Not only could I not Express RMA the PSU, but there was no telling when I would receive a new PSU if I used the normal RMA process. I do not have any spare PSUs laying around, so my brand new, gaming system would be an expensive paper weight indefinitely. My only other option was to obtain a refund, which if approved is still going to take 6 to 8 weeks. Thanks a lot Corsair. Even as a long time Corsair fan, I can't recommend that anyone buy a Corsair PSU at this time. Completely unreliable out of the box. Avoid unless you want to go through a lengthy and painful RMA process.

Pros: This power supply is simply the best I have ever owned over the past 15 years. Everything about is first rate. Corsair Link software works via USB without the need to purchase any link extra link device from Corsair. Ignore other reviewers who say the link software does not work without an extra purchase.

Cons: Probably overkill for most people, but if you want the best, this is it! Many will wait for lower power versions. Some of the Corsair Link Software readings are inaccurate. The link software shows the efficiency of the power supply to be anywhere from about 3 from 3 to 6 percentage points higher (95 -98%) than it should be. Corsair needs to fix this.

Overall Review: As usual, Corsair hits a home run with this power supply. Combine this with their excellent support, and 7 year warranty and you have a Product of the Year candidate. Finally, the Corsair Link Software is very nice, but it is not all that. I do not see using it very much once the novelty wears off. The IMPORTANT aspect of the power supply is its performance! The software is just the icing on the cake.

Pros: Unlike others reviews I haven’t noticed any quality issues with the cables. They are a little stiff, but no worse than any other modular PSU’s I’ve owned. It is incredibly efficient as well. 10 year warranty. The PSU itself seems to be excellent quality.

Cons: Although Corsair’s website says it works with iCUE it does not yet, and I confirmed this with a Corsair rep. I find that ironic since this is arguably their newest “flagship” PSU. It’s expensive, although now it’s $80 less than it was a few month’s ago when I purchased it, but still expensive. Probably more wattage than I will ever need. I figured with an overclocked 7980xe and 2 GPU’s a little extra head room wouldn’t be bad...but still overkill. As others have mentioned it really should come with more cables.

Overall Review: Good luck opening a support ticket for it with Corsair. There isn’t an option to choose this product on their support site. So there is no way to open a support ticket online. It boggles the mind how they could over look something so simple.

Pros: Silent, NO Coil Whine, Efficient, Just Oozes nice construction. Love this thing so far. 10/10 @ jonnyguru not an easy task They put a mini-usb-B jack on the psu for the usb/link interface and ditched the tiny-connector-to-huge-usb dongle cable that the 1200i came with. Great move for reducing cable management clutter.

Cons: NONE.. (lil pricey, but no regrets)

Overall Review: Its pretty long, makes the 1200i seem like 'normal' sized psu. I like the non-braided flat cables shipped with it, as they are easier to completely tuck and hide. But may not be the case for everyone.
