Loop order has practically no effect on cooling.

Subbed man!
Also yeah what i've been told/learned is that loop order doesnt matter as long as the pump is below the reservoir so it will never ever run dry, just look out for that.
Other than that, make it look as clean as possible with not so much tubing and it'll be done thumb.gif

why have it go from one rad to the res to another rad??

why not have it go from the gpus to a rad to the cpu to a rad back to the res?

Well as a past proud owner of GTX 480 sli water cooled (which i believe was rated at 250 watt each same as GTX 780ti) I can tell you for a fact that I had to get a 5000 btu a/c window unit for use in the summertime because my room got so hot while gaming.
I had the hot water from my video cards going to a 3x120mm rad just like the op (not same rad but same size) and let me tell you the air was hot coming off the radiator ( I believe I was using 2000 rpm fans also). I would not want that hot water hitting my cpu.
Well he can install his loop as drawn and if he finds that he has high cpu temps he can replumb the loop as tubing is very cheap.
Good luck op with your awesome build I look forward to seeing it completed. thumb.gif

Why not get a 2x120 instead of the 2x140, place the 2x120 on the bottom.

Also, please note that the water-cooling diagram in the original post is subject to change. I am taking into consideration almost everything that everyone in this topic has mentioned. For example, using a 2x120mm rad instead of a 2x140mm, and placing it on the bottom (Thanks IBIubbleTea) and having the loop go from RAD -> GPU -> GPU -> RAD -> CPU -> RAD (Thanks Master_Shake and division2)

I will begin assembling the build tonight once I get home from work. This is going to be a long day at the office... redface.gif

Question, is an 850 watt power supply enough for an OC'd z87 water cooled build featuring dual high end radeon cards in xfire or dual high end NVidia boards in SLI?

No problem, Im planning on doing what your doing but this is my planning build.

Using the same full copper rad as you like 3x120 and 2x120 on bottom, for the bottom, idk if the rad would fit because it sticks out a bit near the end...

To be honest, you'll notice that I ordered an AX860i for this build. I plan on swapping this out soon with an AX1200i just to be safe, considering these full fledged GK110 GPU's when over-volted draw a significant amount of power.

On stock with no overclocking? You should be fine with a quality 850W or 860W PSU.

What about mild over clocking? Or just over clocking of the CPU only? Im going to be doing a micro atx build with either dual GTX 780's or Dual 290x's with a 4770k, with a water cooled system sporting a 35x pump,2 small radiators and couple of SSD's and regular hd's I would like to grab the AX860i, but not sure if its enough for the setup. Kind of have a $200 budget for the PSU and really like the COrsair AX i units. So my build will be very similar to yours, just in a smaller form factor.
