Corsair AX1200i Power Supply Review - Corsair has a refresh today that talks to its high end line of high power PSUs. The AX1200i comes in touting "platinum" efficiency and "an unprecedented level of monitoring and performance customization." How does the AX1200i perform out-of-the-box and does it actually bring value at its huge price?
 
Too bad about this PSU. I was hoping to see something better for the kind of money it's selling for. Corsair may be depending on its reputation too much these days and think customers will buy based on name alone.
 
Great review.

I have had no problems with my Corsair PSUs, and I have a bunch of them.
Specifically my AX1200.

I am a loyal customer and have alot of Corsair products.

I was hoping to see this 1200i bring something new to the table, but it seems pretty meh, compared to the AX1200.:D
 
I was expecting better after looking at the J.G. reivew of this beast. Its a shame it didnt do better. Hopefully Corsair can role out some more platinum PSU's out.
 
I have the AX850, and I love the thing. It is first class all the way.

Hell, the thing comes with a purse to keep the extra modular cables in :)
 
There're many things wrong with this review (according to a not so good performing sample).

According to JGuru and PCPer, this is the best regulating unit in the market, with it's ripple suppression only matched by the HCP-1200, which is an inferior unit in other ways. Also, this unit's build quality is unmatched, making it THE best PSU on the market.

I find it silly that the review is suggesting the Lepa G1600 over this unit, which is clearly an inferior PSU. Also the way it suggests the Lepa (buying the biggest PSU so that you can be done with buying PSU's for years) is silly as well. "Being done" with buying a PSU doesn't mean you should go and buy the biggest PSU you can afford. It simply means you should buy a PSU according right to your wattage requirements.
 
If the change to DSP control makes this unit absolutely outstanding in our performance metric than this expensive, currently, change is certainly a step in the right direction.

Word salad.

Well I guess if you prefer we could just copy everyone else's results and not point out the issues they miss. It sure would save us time!

You get more wattage for less money, and still have an excellent performing unit. Why wouldn't you buy the G1600 over the AX1200i?
 
I'm surprised you didn't give it a Silver award. This kind of efficiency, voltage regulation and ripple control isn't something you can easily achieve at the same time. Of course these aren't enough to justify its price premium, that's why it shouldn't get a gold award.Software control isn't making a "wrong" thing "right". It just adds some flexibility to the PSU.
 
how does this review scale with the newer prices? the lepe g1600 is $329.99, the ax1200i is at $329.99 +FS and the ax1200 is at $249.99 +FS. i had an ax1200 in a monster system that drew over 1100 watts and it performed awesomely. hated selling it but wouldn't fit in my new build. at the price point, looks like the ax1200 is still the best buy of all 3.
 
this unit should win a Gold award for sure
but if Corsair could remove the software feature and reduce price will be even better!! (Diamond award if available)
 
you cant buy the normal AX1200 can you anymore? Im wondering which you be better for my LN2 bench rig?
 
i wouldn't even look at the ax1200i over the ax1200 for the money. the software isn't worth an extra $80 in my eye.
 
It's still a very nice power supply, and to some the extra money isn't a big deal - it is an enthusiast grade PSU afterall.
 
Great review and not what I was expecting really. kinda bumbed, wanted to see advances form my AX1200.
 
Great review I owned a AX1200 and was looking to purchase a Ax1200i. Looks like ill stick with another AX1200 and save a few $ for other parts
 
I have the AX1200 powering 3 7970s with a CPU clocked at 4.7ghz. No issues ever. Looks like the AX1200i is rebadging with some "bling" and a higher price tag. No thanks, I will stick with my AX1200.

By the way, some dude over at Asus RoG was using it to power 2 x ARES ii (yes quad) with an OC on the 3960x at 4.6ghz on the CPU, an SSD, an H100 running benchmarks and all. Granted its a bench rig but still a single AX 1200i running all that is not too bad.
 
That's what I'm going to run, was worried the AX 1200 would not be enough. Just got the first ARES II in today, 2nd ones a few days out...
 
With one Ares II at full load the system is pulling 990 watts. I don't think the AX 1200 is going to be able to handle two cards at full load. I'm going to replace the AX 1200 with a LEPA G Series G1600-MA...
 
If you're getting $3k of GPUs, spending a bit more on the Enermax Maxrevo version of that LEPA seems like the way to go to me. Better transient filter among other things.

For what it's worth, I agree with the review's final rating.
I don't see anything worth that much more money over the AX1200, though those ripple measurements (which are backed up by other reviews) are epic.
