Corsair’s attention to detail and understanding of the enthusiast community has allowed the company to evolve from a memory manufacturer into a well-regarded supplier of cases, cooling hardware, input devices, PC audio, power supplies, gaming accessories and storage devices. Their latest product, the Corsair AX1200i Digital ATX Power Supply, takes things a step further and blazes a trail by adding some innovative and useful features not found in any competing products.

The Corsair AX1200i Digital ATX Power Supply’s name hints at this PSU’s 1200 watt rating, but beyond its monstrous power output, the AX1200i is also highly efficient and sports 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...

Certainly puts my own PSU to shame. Mine isn't even half the wattage on this thing. If only...

Corsair makes some nice PSU's this being one of there top end units it seems. I am sure most here would know a PSU is a major consideration in and on a build. Most consumers in general do not even think about it. A power supply is something I replace regularly on commercially built (HP, DELL, SONY etc) computers for customers. I use one personally and would consider them in the rankings with Sea Sonic, and Sparkle and a few other super premiums I have used for years.

Whats the most important part's to a PC? Motherboards and PSU's because everything else works from them and if they go out so does everything else!

Yep, learned that a little while ago when my motherboard started to go out and none of my peripherals would turn on.

Certainly a very neat PSU with many features. I was impressed when they first announced this. Sadly that price range is far from my reach :(.

Keep it up Corsair!

Saw a video review on this unit and everything about this ps is super cool. The sleeving, fully modular cables and the Corsair Link module all make it a great buy, but as Inspector said out of my price range as well. Plus I don't think I would ever need that much power unless I changed my mind about crossfire/sli.

Wheeew ( long whistle) That's an incredibly large power supply. Honestly aught to be able to power atl east 3 high end graphics cards and insanely fast unlocked cpu and a cooling system without using its full capacity, good job corsair you have really out done yourself, the slightly more financially adept enthusiasts are excited while the rest of us drool and dream of the capabilities.

Corsair don't make the PSU themselves, it is extremely likely that this PSU is made by Seasonic or Flextronics.

Any plans for this kind of tech in the 750W-850W range?

+1 on the picture. There is already an an established Corsair AX series that's very popular with enthusiasts, so I could see the AX [wattage]i series trickle downwards in the wattage rankings.

Honestly though, this PSU is really feature packed, and if I were to build a new system and had unlimited funds, it'd definitely be my PSU of choice. 

People do seem to buy wattage way above their requirements, though. Power Supplies are most efficient when at around 80% load, so if you're running 450W of power out of an 850W power supply, you're wasting efficiency. I assume people will buy the AX1200i for the same reason they buy any high ticket item; so they can say they have it. 

It is very pretty though, I love how rugged it looks.

This is less of an issue with this (Platinum-rated) PSU, it's over 92% efficient from 250W to 1000W!

Still, every time I see a review for these behemoth power supplies, I can't think of a recent single-GPU system that could even use half the 1200W...

 

It's just epeen in most cases, really.. I'd totally get one if I had the funds, though. (;

I currently have one of these: http://www.highpower-tech.com/eng/product_page.php?class=20120223111223&id=20120223112254

It's pretty excellent, in most cases.. cable lengths are pretty horrific though.

Having a higher wattage power supply isn't a complete waste.

Due to Electrolytic capacitor aging (wattage output from the power supply decreases overtime), it is safer to have a power supply wattage higher than your max load. Cheaper power supplies typically have lower quality capacitors.

Temperature and load effective the life of a capacitor

You could replace the capacitors yourself if you wanted to.

It's like you're moving and the power supply is your vehicle. A low wattage power supply is a compact car and a high wattage power supply is a truck. The truck can handle more and it can make the move easier, but it can be a waste if you don't have too much stuff to move.
