    • Worth the price for mission-critical PCs
The Corsair AX1600i is a premium power supply that is an excellent choice for custom builds and mission critical PCs, especially in areas with frequent power problems. I bought the Corsair AX1600i to replace an aging ThermalTake 1200 watt power supply that would no longer power up my PC. The Corsair AX1600i was easy to install and has been working perfectly since I bought it. The Corsair's self-test mode allows verification of the power supply's proper operation before installation. The self-test mode eliminates a lot of stress if you aren't sure whether your PC's problems are caused by a faulty motherboard, CPU or power supply. Corsair's bundled iCUE software allows real-time monitoring of the power supply's temperature, wattage, voltage, and fan speed. The iCUE monitoring software is well-designed and attractive — a big confidence booster that adds value. Other important pluses: 1) the AX1600i uses latest technology Gallium Nitride transistors and premium Japanese capacitors for super efficient, reliable operation; 2) it is fully modular; 3) it automatically adjusts to American, European and Asian voltages; the power supply is extremely quiet. The AX1600i is heavier than most power supplies at 11.5 lbs., but I had no problem fitting it into my case. It's expensive at $619, but a bargain considering its quality components, outstanding features, performance and reliability. If you are investing your time and money in building a high-end PC, I highly recommend the Corsair AX1600i. ... show more

Very high quality components not just high power!

    • Reliable performance and quiet.
The good GAn power supplies have earned their reputations. I don't like running power supplies near their limits. But I have run this AX1600i at 1590 watts continually for over a year, and it has not complained or given me any problems. Its has been a good power supply for a trouble-free quiet build. ... show more

    • The Best PSU
It's big. It's expensive. It is also the best PSU out there. My last PSU, a Corsair RM1000, I have had for 10 years and it is still going strong. However, since I was building a new PC, I figured I would go with a new PSU and decided on the fully digital, fully modular Corsair AXi 1600i. It is at the top of a lot of Best PSU lists out there and since I have had success with Corsair PSUs figured I could not go wrong. I like the full visibility you get through the Corsair iCUE software when you connect the PSU to an available USB header. I am getting plenty of good, clean power and high efficiency with this PSU. I am looking forward to getting another 10 years out of this one! ... show more

Power supply bad out of box. Replaced known working PS with heavier duty one with cable to support expansion. No joy. Removed all load except MBoard and case still no joy. Replaced 24 pin ATX cable with old. Power check before plugging into MBoard, ATX cable melted. This is something QC should have caught. ... show more

    • Solid!
Amazing product, Corsair always deliver, one of the best power supply you can buy right now. Soon as I got the package, very fast delivery thanks Amazon, everything looks premium from the box to the product itself nice materials and solid build, it is also pretty heavy which is always a good indicator of a high quality power supply. I bought it because is fully modular and I want a perfect wire management for my rig, the cables are long enough it comes with all the connectors you need, I personally use it with a ryzen r7 1700x two rx 570 and 16gb of ram without a single problem. I recommend this power supply to everyone who want top quality and power ( I know some of you will say 1600w is too much ) very silent I can barely hear it, different protections so your rig is safe, super happy with this purchase great job Corsair. ... show more

    • KING OF 1600 WATT POWER SUPPLY
MUST BUY! great for Crypto miners to run 24/7 everyday of the week with their 10+ 1080 ti rig config (2 PSU needed). The efficiency im getting running 10x 1080 ti is 93-94%. This PSU came out on January 2018 and has better tech then the typical EVGA Supernova 1600 which came out 2014 which was 4years ago. Its very quite! its compact, and they use GALLIUM NITRIDE for their transistors and everyone will follow suit. Voltage regulation is awesome through their corsair link. Along with the cords it comes with, if you know your not going to use 3 or 4 of the cords, you can sell them for $15+ each online to recoup some cost. But jokes a side, this is a great power supply, even if your not a crypto miner, this is by far one of the best PSU for gamers too, and everyone knows corsair products are top of the line. ... show more
