PSU and CPU-Cooling recommendations?

[Agito]

Hi everyone,

Been a while since I bought my last product from PCS, but I'm back for second serving.

In November I'm planning to splash out on a new PC. Budget at £2000. I'll be taking a GTX980Ti initially but I am planning on expanding to SLI in a month or two after. How much power would I need from the PSU? Also would like a recommendation on a CPU fan. I'm going after quiet, so have that in mind. I won't be overclocking so no water cooling please.

Full envisioned specs if that adds to the PSU recommendation:
MOBO - Gigabyte X99M
CPU - i7-5930k @ 3.5Ghz
GPU - GTX980Ti - Future SLI
RAM - 16 GB HyperX Predator @ 3Ghz
System HDD - Any SSD 250GB - 500GB
Secondary Storage - Any HDD 3-4TB

Much appreciated! Please let me know if combination of some parts listed isn't good also.

850W will power sli 980ti's - at least it will on the skylake build I have on order. When you click 'proceed' in the configurator it will tell you if it isnt sufficient
The corsair H100i GTX Hydro should be sufficient cooling, as far as I know, if you get a premium case.

850watt is cutting it close, and the Titan air cooler is more than sufficient, and will provide you with a decent overclock should you change your mind.

Good point. I checked with PC Specialist on the headroom as I too may well sli 980ti's (I am one of those patient Azure customers ) For that build the power usage comes about 50W below 850 BUT they allow 20% margin and the CPU is overclocked to 4.6 (hopefully...)

Edit - missed that you said no liquid cooling...

For your spec the minimum would be 1000W

So we're talking 1kw PSU then just to be sure right?

Yes

If you plan to overclock the 980ti's at any point that will add another 50-60 watts, plus additional HDD's, fans etc will eat another 40-50, so it's always best to factor in future upgrades.
