They are designed to do just that, deliver their rated output 24/7 with no problems. That's why we pay a premium on quality PSUs.
We don't have to baby them as much as we think we should. They can handle it.

No, that PSU can deliver a lot more than 1200W without a problem.

I've killed too many PSUs to feel that way. To be honest, with literally thousands of builds under my belt, and having a long record of almost all of it all posted online, I haven't killed much in the way of hardware die unless it was PSU-related, or because I was shoving too much current through a chip. I just popped a 1200W PSU on OC a few weeks ago. Lost a couple of SSDs when it went. I have a Silverstone 750W PSU that can push clocks higher than my 850W Corsair TX PSU, easily tested with this high-power rig.


Not all PSUs are rated the same way.


Corsair 860i is rated for 860W on 12V...150W on 3.3/5V...but not 860W+ 150W.

So, it's actual capabilities are less than that 860W, if all you do is compare 12V power draw from CPU and VGAs. You need to actualize 3.3V/5V draw and then calculate what you have left over. This is why I say board/accessories matter.

no. it can draw more then 1200w from the wall, it is only designed to deliver 1200w (+ or - a couple %) to the actual hardware itself. being rated at 92%, it can theoretically draw up to (1200/0.92 = 1304w from the wall) give or take a few percent on either side.

while that is true, i dont run anywhere near 1350w 24/7. I also meant that it is screaming because i am pushing it to its rated maximums and the rated maximums are prventing me from pushing harder (technically i could run this thing at 1350w all day everyday, but thats not something im interested in, i would like to run at 800-1000w all day everyday, and 1500w here and there when i wish to bench things to the extreme). i would like to upgrade to lga 2011 cpu and really overvolt things to their absolute max but the ax1200i would likely shut down on my first firestrike run so i will push off a a cpu upgrade until the 5960x hits shelves, by then ill migrate to the new evga 1600w or the corsair ax1500i.

No, I'm telling you that this particular PSU can deliver a lot more than 1200W. Ask around. It's not the only PSU that can easily deliver a lot more than its advertised capacity. The 1200W Antec High Current Pro is another one.

 

I'm not talking about the power draw at the wall (and you don't need to teach me anything lol).

"alot" is subjective. there was a review i read which i am currently trying to find where it was able to deliver 1240w of power to the hardware (1347w drawn from the wall), before it would begin shutting down. they are rated to deliver 1200w of power to the hardware, like gpu's some will fair better then others. whether that means some shut down the second you try to send 1201w of power to the hardware or a few percent more obviously varies. I doubt many if any corsair ax1200i's would be able to deliver over 1300w of power to hardware. i would put you're theory of "alot" more to the test but i doubt you would paypal me $350 if my psu went pop.

It's not a theory. I've seen some of the true PSU experts on here saying so and they provided proof. What's that proof? I can't remember. All I know is, I saw it (I think it was either earlier today or yesterday).

 

Anyway, you're not telling me anything that I don't know. I mean, yes, I know that the AX1200i is designed to be able to continuously deliver 1200W.

 

Why are you being so argumentative or whatever? Let's be a little more friendly toward each other. There's no sense in being any other way.

Aw thanks man, but I'm referring to proof that was provided about the AX1200i's ability to deliver a lot more than just 1200W pretty easily.

 

I'm a bit under the weather and also quite tired at the moment - and I'm eating dinner, so I really don't know if I want to start a project of trying to find it right now.
