CorsairAXi Series, AX1600i, 1600 Watt, 80+ Titanium Certified, Fully Modular - Digital Power Supply (CP-9020087-NA)

Perfect is exactly what I needed, it comes with everything.

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.

Very high quality components not just high power!

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.

Sticker shock can get the best of us. But there's a reason why this overengineered PSU cost as much as it does.Hardware:It's rock solid. Nothing inside the PSU is cheap. Fans are quiet out of the box and cools nicely. The stock cables are ugly (what stock cables aren't lol). I bought Corsair colored replacements and they fit like a glove and look spectacular.Software:This is where it REALLY shines. The amount of important parameters this PSU allows you to monitor is insane! Almost anything power related you can think of, you'll be able to monitor via Corsair iCue. You can adjust your OCP for literally every single output on your PSU ON THE FLY as well as switch between single-rail and multi-rail right from the app. You can also adjust fan speed and set a curve based on not only the PSU temp, but really any other temperature the iCue software has access to (and that's a lot).Also, the fan is near silent at high speeds!This is THE enthusiast's PSU. But I recommend this PSU to literally everyone that is concerned about buying twice. This is a one time purchase ordeal with this PSU. Get one.

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.

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!

Works great
