So, I'd be like, "Yeah? So, what's the voltage?" You see, 100A on 1V of power is 100W. On 2V, it's 200W. On 3V, it's 300W. So, on 12V of power, that's 1,200W. On 120V of power, that's 12,000W.

 

The modern PSU has multiple voltage outputs: 3.3V, 5V, and 12V. So, let's talk about solid state drives again: my 840 EVOs say that they pull up to 0.86A on 5V power. That's 4.3W.

 

I hope this clears it up (I hope that I understood the question).

Like I said before and like you discovered before, your computer is not consuming any more than 600W. That's combined between all of the PSU's voltage outputs, not just 12V. So, how much of that 600W is being taken out of the 12V output? I don't know. If I had to guess, then I'd guess about 500W because of that review I posted. I really don't know though because we would need a Digital Multimeter to really figure it out.

I honestly don't know. This is way beyond my knowledge. However, that PSU is entirely different. It's not even a SeaSonic unit. I think it's Flextronics. Very different.

Good luck. :/

What I take from you was 600 watts of power can't exceed 71 amps (max amps on 860 for 12v) because 71 amps is about 850 watts. There's no way I could be pulling 600 watts yet 80amps on the 12v right?

My rigs not pulling more than 600 watts on a hard day, were both pretty sure of that

Would never guess corsair customer service was that bad. I'm gonna try 'em anyway though

Got an old hx 750 I might try out too,

again ,thanks for your input, if not expertise, in these matters

80A on 12V power is 960W. Always multiply the amperage by the voltage. So, 80 x 12 is 960.

 

Again, that 600W is the entire computer's power consumption. It's a combination of 3.3V power, 5V power, and 12V power. That 600W is not all on 12V power. If it were, then your Kill A Watt reading (multiplied by 0.90 for estimating 90% efficiency) would have been higher than 667W. Does this make sense? I have a pretty bad cold and I feel like I'm off in space, so please tell me if I'm still not clear. I long for being "clear" again. lol

 

Think about it for a minute though: your entire computer was pulling about 600W out of a high-end 860W PSU. This PSU is capable of easily delivering 860W 24/7 ("continuous"). So, delivering 600W should be a walk in the park for it.

 

Actually, wait: am I correct in assuming that your Kill A Watt reading was 667W? You said that you found your computer to be pulling 600W from the PSU, so I assumed that you saw 667W and multiplied it by .90 in order to estimate 90% efficiency. After all, 600W at the wall would be 540W, which is a little on the low side for two 780 Ti's.

You're welcome, JB! May I call you JB? I kinda like it! hehe I sincerely hope that we figure this one out. If the HX750 doesn't shut down on you, then I would just keep it on the HX750 and perhaps conclude that the AX860 is somehow incompatible with your system. I don't know how that would be the case, but hey...

Sorry I wasn't specific there cables, I understand that the 600 watts were a combination of all rails but the 12v alone has a max of 850. What I didn't understand before you explained was if I could exceed the amperage without exceeding the wattage but I understand now 71 amps equates to 850 watts. Don't know if that clears it for you, but if it doesn't, just know I understand and agree with assessments lol

JB's fine by me, if it saves you a few keystrokes

The main reason for all my troubles here is that I already have an 860 and bought a 1200i ,because of this problem, for about 400 rush delivery on newegg (damn miners!)

I want to keep the 860 and return the 1200i and save myself some money, I also feel like corsair owes me

My little problem in a nutshell

71 x 12 is 852, but of course now I'm just being anal. :)

 

Anyway, see what happens with the HX750 first.

I will, as soon as I find time to gut my entire PC again

Also depending on how corsair responds, I might keep the 1200i

This is a GREAT discussion.

@TwoCables: Fantastic job explaining what the numbers mean, how they're derived, etc..

Now that I'm caught up I'm wondering if there really is a power delivery problem. I've been using Corsair PSU's for a while now and I have had to exchange a couple out in the last few years due to excessive whine or something like that. Never had one cut out on me. The odds of getting three in a row are just astronomical. I am very curious to see how that HX does.
