I am looking to build a new computer with following components.

- i5 4690k CPU
- MSI Z97-GAMING 5 MB
- G.Skill Sniper 8GB 1866 DDR3
- Crucial MX105 512GB SSD
- Sapphire Radeon R9 290 4GB Tri-X
- Cooler Master COSMOS SE
- Corsair H105

I don't have a PSU picked out yet. I heard that Broadwell needs a specific voltage support. But I am not sure where to look for it. I am looking at aroud 850W to support Crossfire R9 290 with price range around $150.

The components are picked out to semi future proof and be able to upgrade it easily without wasting any parts. Any recommendations and advices are welcome.

You may want to reconsider planning for R9-290 cf.
It looks like you may need a stronger psu:

If you do want to plan for dual cards, wait a week and see what the GTX980 offers. Maxwell is supposed to be much less power hungry. I might guess 700w for sli.

I have become a bit jaded on the subject of haswell cooling for overclocking.
How high you can OC is firstly determined by your luck in the bin lottery.
I had high expectations from the Devil's canyon parts and their better thermals.
I found out that the thermals really do not matter unless, perhaps, you are a competitive overclocker.
Haswell runs quite cool, that is, until you raise the voltage past 1.25v or so.
Once you go...

Once you go past 1.3v, then you really do need very good cooling to keep stress loads under say 85c.
But, voltages higher than 1.30 are not a good thing for 24/7 usage.
Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
My thought is that it is better to use the exotic cooling funds for a quieter and less expensive air cooler.

Only think you have to worry about when it comes to power supplies and Haswell/Broadwell is that they can output voltage at near zero load conditions. And this only applies if you leave the power saving features turned on. If you are overclocking and not letting the C-states control the voltage it doesn't matter. Also, all of your fans, GPUs, etc will create enough load for the power supply to stay running.

Corsair HX850 or an XFX850W Gold would be my pick for a power supply.
