Picking PSU, need help!

Hi, I'm building a PC, I've got help from an awesome friend who got me through all this build, but I'm still a little dark regarding the PSU! If you guys could help me would be great!

Would like to give a shoutout to Zircoben for the awesome help he provided me throughout the whole part choosing.

So guys, this is the build I'm going for.
Specs:

MoBo: Asus Z97 skt 1150
CPU: Intel i7-4770k
GPU: Evga GTX 760 Superclocked ACX 2GB PCI E 3.0
RAM: G.Skill 8GB (2x4) 1600mhz Ripjawz
SSD: Samsung 800 Series Ultraslim 250GB
HDD: Seagate Barracuda 2TB
Case: NZXT Phantom (Fully Fanned)
PSU: (????)

So that's it, in the future, couple of months ahead of those buys, I might add two more sticks of 4GB to the ram, might aswell, upgrade the GPU to either SLI with another Evga 760, or just a GTX 780 ti(just that, not SLI a 760 with the 780), and also, I might overclock that CPU to either 4.4Ghz / 4.6Ghz and for such I'll add a Corsair H100i.

So what do you guys recommend me to get as a PSU for such things, the ones I'm going from scratch plus the addons I mentioned and the GPU upgrade?
If you have any tips regarding the current build, I'm open to ideas. :) 

Thanks in advance!

How about this, its a very reliable PSU, I've had it in previous builds certainly not cheap but expensive is better as you will never or really unlikely to encounter problems with this PSU


and also, good luck with your build it looks great!!:D

XFX XTR 550w will do just fine. Very well made PSU for the price.

If you're thinking of going 760 SLI then get a 700w PSU minimum. The Builder Series 750W PSU by Corsair is a good PSU for its price.

this will allow for future upgrades and/ or future SLI. also, you don't need more than 8GB of RAM...you'll never use more than that unless you are doing intensive workstation applications and such

So that Evga one, is it a reliable brand? I know it is regarding GPUs, but PSU? Isn't the XFX better? And 750W is enough if I decide to OC the CPU, add an H100i and even SLI the 760 or and regarding my budget replace the 760 for a 780? Is 750W just enough?

750W is enough for all of that. I'd recommend Corsair over EVGA personally but that's because I'm biased. I've used Corsair in all of my builds and never had one fail.

Or would this do a better role?

For the EVGA GTX 760, it has a system requirement of "500 watt or greater power supply with a minimum of 30 amps on the +12 volt rail". So a 550-650 watt power supply is recommended.

For the option of a GTX 770 or GTX 780 , it has system requirement of "600 watt or greater power supply with a minimum of 42 amps on the +12 volt rail". So a 650-750 watt power supply is recommended.

you most certainly be better off with a good quality 700watt minimum psu from respectable manufacturer...due to the way AMD and Nvidia engineer their gpu and driver, the gpu's clock will jump up and down pretty aggressively(biased towards lower clock for lower power consumption and more pronounce in AMD latest gpu); power consumption is not a smooth curve or straight line like previous generation gpu whose clock remains static during 3d use, it's more like of a spike(a nasty one)
for example the gpu might go from 230watt all the way to 120watt and back all the way to 250watt in less then 1 second(note the amount of power consumed is well within a 700+watts psu specification but it is the sudden spike and valley that can kill most mediocre quality psu). I would rather spend a little more to buy quality PSU that can handle the punishment a modern pc can throw at it. correct me if I'm wrong. Great build by the way ;)

Isn't seasonic a reliable PSU brand?

Thanks for the feedback on the build though. :)

Seasonic is one of the best brands. I would recommend that power supply.
