i7 6700k + Pascal Titan X + Predator 360 Power Requirement

[Kitkatko6]

My plan is to build a new computer in the upcoming week or two. With the release of the Pascal Titan X on August 2nd, I am going for that with an i7 6700k both paired with the water blocks and rad in push or pull for the Predator 360 AIO cooler from EKWB.

Question is, with all that, the 6700k OC'd to around 4.5GHz, a single 1TB SSD, 16GB DDR4-3200MHz RAM, and taking into account the 6 fans, would a 750W power supply be sufficient for the task?

A Titan will be ~250watt TDP. if you going to overclock it - 300Watt under load + overclocked CPU 100watt under load + rest components 100watt
that is ~500watt under full load. Realistically the power usage will be lower in games. So a good 750watt PSU will have no problem with it.
Though I'd prefer about 850-1000 watt PSU to keep it at ~50% capacity under load.
Another thing, 360 rad is not that great for such high TDP. It would be fine for GTX 1070/1080, but with titan i'd go for 480 rad (240+240 is also fine).
In your case, would be better to look at more custom solution that includes D5 pump (XSPC Photon or something similar from EK).
Regarding push and pull, there is 0 practical performance difference (same as with loop order, the only important thing is that res comes before pump).
But from maintenance point, pull is better as you can clean the rads without removing the fans (here a video on this matter https://www.youtube.com/watch?v=UyC3lZ5WFMk )

A 360mm rad is more than enough. Even at 1850RPM the entire loop can dissipate ~650W TDP, and seeing as only the GPU and CPU are in the loop, with a 400W TDP would give me enough headroom to even lower the fan speeds. But thank you for the power supply suggestion.

I'm talking from experience. I had a heavily overclocked GTX 570 which was running at bout 300Watt + i7-4770K running at max 125Watt.
So the GPU and CPU were about 60C while gaming.
Today I have GTX 1070 which is much lower TDP even overclocked and the temperature of the GPU is typically around 40-42C and CPU is around 48-50 while gaming.
The radiators (120+240) are relatively thin and low FPI (from swiftech) but i like it due to low noise. So this is the reason I'm suggesting larger rad surface for your setup.
You are totally right about ability, but at what noise level and what the final temperature of the components you are trying to achieve.
