The best enthusiast PC power supply you can own.
AX1500i defines the state of the art for enthusiast-grade PC power supplies. It provides 1500 Watts of continuous, digitally-controlled power on 15 Amp circuits of 115V or higher, and 80 PLUS certification with an incredible 94% efficiency rating. Zero RPM Fan mode ensures silent operation at low and medium loads, and the fully modular, low profile cable set makes for easy installation and great-looking builds.
Provides 1500 Watts of reliable, continuous power for high-performance PCs
If you’re building ultra high-end performance systems or pushing world overclocking records, you know it when even 1200 Watts just isn’t enough. The AX1500i reliably delivers 1500 Watts of continuous – not peak – power on demand. And, you don’t need any special household wiring to make it happen… you’ll get 1500 Watts of clean, stable power on 15 Amp circuits of 115V or higher.
Digitally controlled power
The AX1500i is designed around a DSP for increased efficiency, tighter voltage regulation, and superior electrical specifications. The elegant, DSP-based design reduces internal component count and allows for better control of electrical ripple and noise.
80 PLUS Titanium
The AX1500i, simply put, approaches near-perfect efficiency like no other desktop PC power supply has ever done. Amazing efficiency has so many benefits not only does it lower your operating costs, but it generates less heat, too. And that means that there’s less cooling required.
Zero RPM Fan Mode
In fact, most of the time, no active cooling is required. The fan simply doesn’t spin. And when you’re pushing it hard, the thermally controlled fan adjusts its speed to match demand. The custom-designed fan is extra large, with a diameter of 140mm for low noise even at full load.
CORSAIR iCUE desktop monitoring and control
The AX1500i to a motherboard USB header with the included cable, and you can use CORSAIR iCUE to monitor power input, power output, efficiency, and internal temperature in real time. You can customize fan speed, and set up your AX1500i to operate as a single-rail or with multiple virtual rails.
Fully modular, low-profile cables
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 improve performance: fewer extraneous cables in your system can reduce airflow obstruction.
Intelligent Control. Unlimited Possibilities.
CORSAIR iCUE provides in-depth PSU voltage and performance monitoring, as well as stunning system-wide RGB lighting synchronization.

Minus 1 star for failing after a little over 2 months. Minus 1 for not responding to support email at all, waited 7 days. Minus 1 for making me call tech support and getting an ear full from them about how customer support is who I need to call even though when I called for the last 6 days, all circuits are busy. Minus a 4th star because your support website isn't actually mobile friendly, there were fields I needed to fill out to create an account and open a ticket that you can't see unless you are in desktop mode. Corsair I've loved your products for a long time but this has been a really bad experience.
Update: PSU has failed again. Sudden random shutdowns even when system has been sitting at idle or just browsing news on the web. I'll be asking for a replacement for the 3rd time. Do not buy this PSU or any from this model line. Would give zero stars if I could.
I have always loved Corsair, and been a die-hard fan, but this PSU has tested me.
After having it for a few months, it started to power off and on randomly. It took me hours of troubleshooting to figure out it was my top-of-the-line PSU.
Corsair support is a nightmare. Dealing with them is frustrating and terrible, and it took me a long time to get this item exchanged.
A few weeks later, same issue with the new one. It's a piece of trash.
Again, took me forever to try to deal with Corsair support to get a new one.
Luckily, they sent me a "lower-end" model this time, since unsurprisingly, this one is discontinued. Hopefully I have better luck with this new model.
Corsair, your support could use a lot of work. The RMA process should be easy, especially if you're going to sell poorly-tested high-end products plagued with issues.
Three of the AX1200i units I received were afflicted by a very noticeable (and patently unacceptable) coil whine. This manifested itself under load (i.e., when gaming) as a high-pitched squeal that was both maddening and disappointing. The PC into which I had built this PSU is otherwise extremely quiet (even with two ASUS STRIX Radeon R9 390X Overclocked 8 GB DDR5 512-bit DisplayPort HDMI 1.4a DVI-I Gaming Graphics Card ). After completing the initial build, I noticed that under load, the PSU squealed quite a great deal. Thankfully, replacing the hard drive in my build with a Thermaltake Level 10 Titanium case is not exceptionally difficult and does not require the "open-heart surgery" that such an event might require in other cases. So, I contacted Corsair and arranged for an advance replacement (wherein you must provide a credit card to which a temporary charge is applied) so that I could get a replacement unit in advance of returning the defective unit.
They promptly sent me the replacement unit and I returned the first unit to them.
The second unit also squealed under load. It was a different pitch and responded to different loads (i.e., games), but was altogether too loud to tolerate (especially at this price point).
Undeterred, I contacted Corsair. We repeated the process.
This time, because stock was depleted, they kindly shipped me one directly from Asia. It squealed under load.
To be clear, the squealing in all three units was not subtle. And it wasn't a function of me being finicky. It was the kind of sound anyone would notice.
Unfortunately, at this point, the unit had gone out of stock (wasn't available on Amazon and Corsair no longer had any on hand). They offered to replace it with the larger AX1500i; however, that unit is too physically to large (long) for my case. So we agreed that I would wait until they received new stock of the AX1500i, and that I would live with the squealing until then. We further agreed that they would first ship my unit to their technical support where they would test the unit for coil whine, establishing that the unit was perfectly silent before shipping it to me.
And so my multi-month wait began.
Four days ago, the whining power supply (the third) failed entirely. This voided the machine's operation entirely. Because putting up with squealing is a completely different ballgame from not having a PC that works, I contacted Corsair to see which unit they could provide to replace the failed unit while I continued to wait. They kindly sent me (in one business day) a Corsair HXi Series, HX1200i, 1200 Watt (1200W), Fully Modular Power Supply, 80+ Platinum Certified . I received it today and installed it. It is almost identical to the AX1200i except that it is not all digital (and consequently requires a USB connection from the PSU to the motherboard to get the fairly useless Corsair Link software to work). Notably, while it makes some sound under load, it's not nearly as noisy as any of the three AX1200i units.
And so I have a replacement unit while I continue to wait for Corsair to ship me an AX1200i replacement unit that operates the way a $310 PSU should.
While I can commend Corsair's customer service, this particular unit is simply not recommendable. The HX1200i may be a better unit for those looking for less noise (although I cannot comment on reliability).
I can say that in 2010, I built a different machine with a Corsair Professional Series HX1000 80 Plus Certified Modular Power Supply (CMPSU-1000HX) . That PSU was virtually noiseless and presented no issues that I recall for nearly 6 years. All told, I believe Corsair makes good products (in all my PCs, I have Corsair memory with 2 X Corsair Vengeance LPX 16GB (4 x 4GB) DDR4 DRAM 3000MHz (PC4-24000) C15 memory kit for DDR4 Systems (CMK16GX4M4B3000C15R) in this build, and I currently use a Corsair Gaming K70 LUX RGB Mechanical Keyboard, Backlit RGB LED, Cherry MX RGB Blue and Corsair Gaming MM800 POLARIS RGB LED Lighting Hard Mouse Pad ), but this is not among them.
Needless to say, I recommend buying a different model if you are interested in the Corsair brand.

la construcción esta por demás decir que es de primer nivel, los accesorios y de mas utilidades son excelentes, el ventilado prácticamente esta todo el tiempo apagado, hasta ahora después de jugar varias horas no ha sido necesario que se active, la aplicación para el monitoreo de la fuente es muy útil.
le pongo 4 estrellas solo por el detalle de que mi caja del producto vino un poco rota de una tapa, como si al querer abrirla no se percataran de que tiene sellos y por eso se rasgó, los sellos unos se encontraban cortados y pare que le pusieron un sello encima para volver a cerrarla, estuve revisando en videos el contenido que deberia traer y al parecer no tiene faltantes.
Salvo por ese inconveniente la fuente es una maravilla, estoy muy contento con ella.
Packaging: If you have opened any high end Corsair power supply, you would know how this is packed. Tons of foam, and 2 boxes protect it.
Cables: A TON of cables are provided. Although they are not sleeved, they are of good quality. I personally use individually sleeved cables though.
Power cable: This monster uses a C19 power cable. So if you loose your power cables a lot, be prepared to spend like 30 bucks on a power cable. It is a really thick cord.
Build quality: If you have only used a cheap power supply before, the heft and thicker steel frame of this power supply will suprise you. It's heavy and well built.
Overall, I would recommend this to people need more than 1200 watts. Although I do not require 1500 watts at the moment, it is a great power supply. However, don't even bother of using this to power you're pentium g3258 and 750ti. Thats wasting money.
Died. No power on, self test light red.
Otherwise fantastic power supply
