Help me choose a PSU!

Intel i7 4770k 3.5GHz Quad-Core (LGA1150)
Coolermaster Hyper-212 EVO
Asus z87-A (LGA1150)
Gigabyte Geforce GTX 780 OC 3GB
G.Skill Trident-X 16GB Kit (8Gx2) DDR3-1600 C7 (1.5v)
(SSD) Samsung 2.5" 840 EVO 250GB SATAIII
(HDD) Seagate 3.5" Barracuda 2TB SATA3 7200rpm 64MB Cache
extra system fans

I cant decide on a good-value-for-money power supply.

I was thinking a 750W supply will give me room for 32GB memory and cpu over-clocking in the future, but I would need more than 750W to go SLI with dual GTX 780's. Thoughts on this? Any recommendations?

Thanks in advance

I would say you'll need more then 750 watts. Overclocking + 2 780s will mean more power. I would say 750 is good enough, but i would be more safe to have 850 watts and more. Just to give you more head room in the future without buying a new PSU.

With 2 - 780's you will need 850w.

Here's a high quality SEASONIC.

Thanks heaps, and what model would you recommend to power a single 780, with the above system (i.e a 750W PSU)?
