Excellent power supply, heavy and durable quality.

This is one huge-*** power supply for this kind of configuration, but I do have plans in mind that will inevitably draw more power. I plan on upgrading my GTX 960 to two Nvidia Titan X's and overclock the whole system once I get custom CPU liquid cooling for my 5930K CPU so I can for once clock the CPU to 4.7 GHz without the temps flying too close to the sun. I found that an overclocked CPU can draw up to 30 amps or more, so for my motherboard, I plugged both of my CPU power connectors. I can imagine that the Nvidia Titan X's can pull more current.

So much power, so much power! Enough power and cabling to light a small city and with the Corsair link system it is amazing. The link software can monitor all you temps and fan speeds as reported by your motherboard as well as GPU and CPU and it also controls the Corsair Mini Commander RGB and Fan hub as well as Corsair AIO coolers. The LINK software is free to download.

It's completely overkill for this build I'm fully aware of it, but YOLO MOFOS. I happened to buy it for 185 bucks and couldn't pass that up. Being able to have something that powers anything I could ever have and not have a fan turn on is kinda what I wanted.

So far so good. Johnny Guru's glowing review sold me on this unit, and so far it seems he was absolutely right about it.

It's a PSU. It powers my stuff with no issues.

Not much to say about this PSU, since it is without a doubt a top pick for the price. 80+ Platinum certificated, zero fan noise at low load, Corsair Link integration so you can check your power consumption at any time and great build quality. Recommended.

The Corsair AX1200i Digital ATX is highly efficient and uses a Digital Signal Processor (DSP) to provide digitally-controlled power and an interface to Corsair’s Corsair Link software for real-time monitoring and control. With a 10 year warranty makes this easily the best of the best, unless your needing more power than the 1500w version is what you will want..

I..Need..More..Power..Scottie. Seriously. This thing packs a punch! Every thing that comes with it is top notch. Cables are very nice, packaging, accessories. I have 4 of them; I think they are that good.
