Trying to decide on the 860 or 1200, i variants. Working 90% of the time in an idle state with office apps and multiple windows, which unit in your opinion would produce less heat into the office space? Considering I'm working 10hours at a time. Thanks man!

If it's the system in your sig, then go for a 760i. Your system probably draws no more than 350W at max load, and I'd wager close to 120-130W idle. On the efficiency curve of an 860 or 1200, you'll be well below 20% during emails and whatnot, which will produce more waste heat.

On a 760i, you'll be right around the 20% mark, though just a bit under it, so it'll be more efficient and produce less waste heat.

Though in all rationality the difference between efficiency on that system on a 760i and an 860i would be pretty small, a couple of watts of waste heat, max, I'd guess. The 1200i is definitely overkill for you though.

Unless you have like 3 of those GPUs.

Still, I love the zero noise love that corsiar and seasonic are giving enthusiast grade PSUs. About a year ago you couldn't find a fanless unit over 150 watts if you tried, now it looks like they might be everywhere.

Just curious, but what PSU isn't nearly silent? I have used many brands of PSUs which are 650/750w and I could never hear the fans.

Otherwise their parts are solid, but the "i" variants are superior.

Aren't the 860i and 760i technically seasonic units? I'm not sure I'm understanding what you are saying here. These PSU's are seasonic platforms with some extra Corsair software basically correct?

I'm pretty sure they're Flextronic units. The AX760 and AX860 are Seasonic units though.

Nope, the "i" variants are completely different platform from Flextronics.

Software monitoring of a PSU requires actual hardware inside that can report the data - and without digital that hardware significantly affects things like resistance or cost. Going to DSP basically gets you the data output free, but the associated costs of going to digital has other implications, which is why the cost is higher.

At what point would it be worth while going with a digital variation over the ax850 I already have? Im sorry if its been answered. I did see the picture on the website with some software but I couldnt enlarge it to see a more detailed view of what it can really do.

edit:
Guess the best part would be the efficiency over the ax850?

Thanks George, I knew the AX1200i was overkill in terms of the power my sig rig needs, was only considering it for the fan profile, really hope the AX860i fan Never spins up just like my AX850.

Woohoo, AX860i listed at Amazon, for $235. not in stock yet though, maybe next week. Nothing at the egg yet.

There are some major issues with the monitoring on the AX1200i, I expect that also applies to the AX860i and AX760i as well since they use the same software. I am getting current values reported that are absolutely ridiculous and bear no relationship at all to the real power being drawn.

Corsair say they aren't aware of it, can't replicate it and that I am the only user reporting it, but I have found videos where it's happening on Corsair's demo systems at Computex.

Here's Corsair's PR director Rick Allen, pointing at the faulty power reading while describing how you can monitor the PCIe currents: http://www.youtube.com/watch?v=ZD8u7-vMSzs#t=2m37s

pointing.jpg

At 2:28, it's doing it on PCIe1, PCIe2 and PCIe3 with 55.8 Amps reported on each (a total of over 2 kilowatts) while total power output reads 174 Watts.

I've posted about it here: http://www.overclock.net/t/1324891/corsair-deny-all-knowledge-ax1200i-software-broken-probably-applies-to-ax860i-and-ax760i-as-well
