I am looking at getting a Corsair AX1200i and this is the first I have heard of this fan issue. Hopefully it won't be an issue if I buy one. Do newer units of the AX1200i have this problem?

I can say without a doubt this is the best PSU we've ever made. I can also say that nearly nobody needs 1500W, so we're looking to bring that technology down in wattage eventually. But there's nothing else like this one right now.

With mining dying down due to summer and the tax laws announced today, I'd think 750W + 850W should be on order thumb.gif

What would you call it though? 750iT, 850iT? 750Ti , 850Ti? or just plain 750i, 850i?

Not to be confused with the GTX 750 Ti

hehe I could build a system with a pair of gtx 760's in a 760T and use a gtx 750Ti as a physics card; all powered by an ax (hx?) 750Ti biggrin.gif

Any details on the 12V rail configurations George? I hope there are 4 dedicated rails for the GPUs...

It's only a "problem" for people whose builds ride right at the fan cutoff point frequently. For example, the fan spins up on the AX1200i around 40% load, or 480W. If your build during games is running between 470-490W the fan would momentarily spin up and then back down, which isn't noticeable on the high-end units because at 480W of load your GPU fans will be way louder than the PSU fan.

We get very few complaints about it and our return rate on AXi series products is especially low.

All AXi products have software-adjustable single or multi-rail configurations.

Ok thank you for the info.

I'll wait for the Seasonic-Based AX1200 without the i, titanium-rated from Cosair with an improved hybrid-silent to 60% load fan profile to appear.

OR just buy the Seasonic 1200watt Titanium, whichever comes first with a Sanyo fan.

Depending on the voltage regulation and ripple (which I suspect will be excellent) this may be the best power supply ever released to the consumer market in every aspect.

All AXi products have software-adjustable single or multi-rail configurations.

I think you minimized the issue.. If you have the fan facing down, having an idle load of 250W (no speedstep+fixed voltage & full clock + voltage on gpu) and an ambient temp of 30-35° the fan was ramping to its max like 20 times per minute. Playing battlefield 3 on low/medium settings so I could manage to keep 120fps all the time, but the gpu load was only around 30-40% average, the fan was kicking who knows even 40 times a minute. The ax860i was nothing more besides a pain for me and more of a fake hybrid psu that required airflow to work.

I'm not really sure how you guys can miss this design flaw and advertize your power supplies like madness as "super quiet" stuff and now there's not even a fix for your current I series like the 760i, 860i, 1200i?

Not only the fan profile should have been tweaked, the fan thats clicking every few secs with some activity (like here https://www.youtube.com/watch?v=cTMG5VJcKvo#t=45) which is even considered to be normal according to ramguy (http://forum.corsair.com/v3/showpost.php?p=615151&postcount=5). It's just silly to see reviewers not even mentioning two design flaws and throwing 10/10's ratings out. If johnnyguru, TPU, guru3d whatsoever mentioned those design flaws, the sales numbers would have been lower.

It's not surprising me that the rma rate is low if you see people running an ax1200i with no discrete gpu in their build or if their case fans alone are louder than the psu or theyre just deaf. I don't think that you shouldn't fix your current I series because the rma rate is low
