Done :)

I got it on Amazon http://www.amazon.com/gp/product/B00GAPU4B4 while it was going for about half its current price on a lightning deal.

Thank you. It's a CoolerMaster mechanical gaming keyboard with cherry mx brown switches http://www.amazon.com/gp/product/B00C2MBG02

Thanks. The H100i and SP120s are both great. I had taken one star off the H100i because I was expecting slightly lower idle temps than I'm getting right now (28 °C). I see a lot of people reporting 25 °C. I just realized though that I took the reading during the day and I'm here in San Francisco which is certainly warmer than most of the U.S in January. Also I looked at lots of reviews comparing the H100i with the Kraken X60 and most of them report the Kraken to be the better cooler, but only by a small margin. The Kraken also offers less control over noise. So in hindsight I reconsider my rating and I have revised it to 5 stars.

The SP120S though gets a 4 star when paired with H100i because it lacks a PWM header, so the H100i cannot auto-adjust the radiator fan speed. On their own the SP120s are great fans. If you care about connecting your radiator fans into the H100i PWM headers, I would recommend the PWM version of the fan http://www.amazon.com/Corsair-Air-SP120-Quiet-CO-9050012-WW/dp/B00C249PEO which costs only slightly more. I often switch between 7v and 12v input to my SP120s depending on whether I'm just browsing or playing a game. I would prefer if the H100i was controlling that. I would have also liked to play with custom fan curves in that case.

So there is my final verdict. An unqualified 5 stars for the H100i and 4 stars for the SP120s. I would also recommend checking out the Kraken before you make a purchase. Good luck.

btw: If your case allows installing radiator fans in a pull config on the top so that they are not visible, I would recommend throwing in some ugly but incredible Noctua fans in there. The only reason I don't have Noctuas all over my case is their hideousness.

At full load, this computer pretty much requires exactly that amount of wattage. Generally, that is a danger, but with the ax760i, it's not really a problem because it is so good. The 760 on the label is continuous power, and even then it's an understatement. That PSU can handle it. http://www.jonnyguru.com/modules.php?name=NDReviews&file=print&reid=317 (ax860i) http://www.techpowerup.com/reviews/Corsair/AX760i/

pcpartpicker reports the total wattage for my system is 757 Watts. The 780 itself has a TDP of around 250W so two of them would dissipate around 500W of heat. Since you can't get more power out a system that you put in, the input for the two GPUs itself would be over 500W. All this should bring my PSU close to its operating limit. In the real world though this rarely happens. I almost never have all my hard disks and optical disks reading/writing at the same time and most applications don't max out two GPUs, and the CPU rarely operates at over 90% load except for small bursts. All this means that there is always power to spare. The only thing I would be worried about is if occasionally the system does reach close to its max rated power and fails to get it from the PSU. This would be bad news for overclocking and for stability of the system.

I did a very unscientific (but real world) stress test with my system. I ran the following at the same time:

1. 8 threads of prime95 at maximum heat and power consumption.
2. A 1080p youtube video.
3. A game on Ultra setting in windowed mode (Skyrim and the new Tomb Raider).

With all of that running, the system barely consumes more than 320W. Although this is a very high load on the CPU, the GPU is probably not as stressed as it would be while rendering large number of polygons full-screen. So there may be rare occasions when the system could still manage to suck in all of that 760W of power input.

Another thing I observed was that the PSU is incredibly efficient and easily manages an efficiency of 85%-95% as claimed.

My main reason for buying the PSU was different though. I got it for $149.99 on an Amazon lightning deal. I would have been crazy to say no to that.

Thanks for the tip. I will check it out.

Fortunately I have zero dead pixels on mine. The ebay seller guaranteed to test for dead pixels before shipping.

The HE500 really need a good headphone amplifier to drive them to their full potential. I have been thinking about gaming headphones but I wonder what they offer over an audiophile headphone other than a mic? I'm guessing they have a certain sound signature more suited to games rather than a linear frequency response that is usually preferred for music. Any recommendations?

Thank you! Please see my reply to CheyTac above. I had the same concerns but that PSU is incredibly efficient and in most real world tests the system will not pull anywhere near 760W of power. I also described a quick and dirty stress test I did in the reply. Also I got a lightning deal on the PSU on Amazon. It's funny I should fall for something like that when I spent 3 grand but I just cannot resist a good deal.

Thanks. Yes, the Noctuas went in the front of the case.

I'm still using the thermal paste that came with H100i. It has worked very well so far and I see no reason to change it. I might try the arctic silver in a few months out of curiosity.

Thanks. The mousepad is a SteelSeries http://www.amazon.com/SteelSeries-QcK-Gaming-Mouse-Black/dp/B000UEZ36W
