AX1200i - Corsair Power Supply - Fully Modular ATX PSU

Corsair AX1200i Power Supply 80PLUS - Titanium

Corsair AXi 1500W Power Supply

If you're building an ultra high-end performance system or pushing for extreme overclocks, and 1200W isn't enough. The AX1500i delivers 1500W of clean, stable power on 15 Amp circuits of 115V or higher. The 80PLUS Titanium efficiency rating gives you almost perfect efficiency like no other PSU and Zero RPM Fan Mode mean that at low to medium loads, the fan doesn’t spin at all. And when you do push the AXi hard, the thermally controlled fan spins only as fast as it needs to. Even when the fan isn't running the AX1500i has specially selected components to reduce electronic noise for a near silent PSU.

Fully Modular Connectivity


AXi Fully Modular Cable Design

Connect the AX1500i to a motherboard USB header with the included cable, and you can use Corsair Link to monitor power input, power output, efficiency, and internal temperature in real time. You can customize fan speed response, and set up your AX1500i to operate as a single-rail power supply, or with multiple virtual rails with customizable OCP points. AX1500i is fully modular, which means that there are no permanently attached cables. This greatly simplifies installation and allows you to use only the cables you need, for a neater, cleaner build. This can also improve performance: fewer cables in your system can reduce airflow obstruction.

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

1500W Corsair AX1500i, Full Modular, 80 PLUS Titanium, SLI/CrossFire, Single Rail, 125A, 140mm Fan, ATX PSU is rated 4.7 out of 5 by 3.
Rated 4 out of 5 by from Excellent, but a real shame about the cables! 5-7 years ago premium PSUs came with good quality cables as standard (remember the Enermax Galaxy?). The individual cables were properly colour coded, used large numbers of small diameter conductors and thin high grade insulation to ensure high flexibility and were properly protected with nylon or textile braid. Then the manufacturers started to use all black cables with thick, cheap insulation leading to very poor flexibility and, as a final insult, eventually joined them all together to form a ribbon cable! I have been purchasing Corsair PSUs since they first appeared on the market place and have used them in over 100 high-end PC builds. However, their standard cables have become increasingly cheap looking, bulky and inflexible to the point where clients, family and friends always insist on aftermarket replacements for their builds. This would be more bearable if their prices were still keen, but the cost of a 1000W PSU has almost doubled in the past 5 years without any major improvements in the quality of other components (I am an Electronics Engineer by trade and I am not impressed by the marketing hype which now permeates this market). I used to run AX1200is in both my main water-cooled PCs, but had to replace the first one when I upgraded to a triple Titan set-up as the 12V rail(s) became unstable past 1088W (Output). I had an almost identical problem when I upgraded to two high end AMD GCs in the other PC when I reached 1104W. Thankfully, the previously purchased Corsair premium AXi cable sets also fitted the 1500AXis. Unfortunately, I needed 2 cable sets per PSU as they lacked sufficient peripheral 4 pin molex leads. Ironically, the manufacturer’s ‘push’ to get enthusiasts to buy better quality aftermarket cables and their availability allowed me to solve this issue quickly and cleanly without having to build my own custom cables. However, a few spare interchangeable (for SATA) 4 pin Molex cables should really be provided as standard given the likely use for any PSU greater than 1000W, especially as many high end systems will be fitted with banks of HD carriers which often use peripheral connectors for power (not forgetting Water-pumps, Fan controllers, RGB LED Controllers, CCL Inverters, Flow Rate Displays, Sound Cards, etc). In fact, I only use one SATA PSU connection (Blu-ray drive) in each of my 6 household PCs, despite them all having 6 -15 HDs. In summary, I would thoroughly recommend this PSU to the serious enthusiasts, but you may need to budget for 2 sets of premium aftermarket cables.

Rated 5 out of 5 by from Fantastic in every way! Picked up this power supply by corsair to replace my XA1000 which lasted me years, and is still kicking, thanks for the recommendation from Scan. Just upgraded my pc recently with an sli config. Great out of the box, fans have only kicked in once on instal. I would recommend this above all others if your looking for something that keeps everything under control when running multi cards and xtreme cpu's - And this can run 4 way sli under no strain. If you are building a super pc, don't skimp on the power brick. I highly recommend this model! Easy 5 Stars!

Rated 5 out of 5 by from Brilliant Highest quality product and stands up to what is advertised, though due to its safety features I suppose it would not allow you to connect a 370W device to one PCI-E line - you need to connect by separate cables. Though I have an older PSU from other producer that allows connecting 400W with one cable and 2 PCI-E connectors (2x6). So literally you would not be able to connect 5 powerful PCI-E graphics cards as it advertises. Though does not high up when pulling 1530W from the wall 24/7. Overall - GREAT PRODUCT, though PRICEY.

Questions & Answers

Where is the AC Power Cord?

Just purchased this PSU and have just opened it up to find there is no AC cord included. The outer box was fully sealed and the inner box has the id label intact over where it opens. I can't believe its not included so has anyone else had the same problem?
Asked by: Shotokanads
It should be in the box!
