Hey there. 3 days ago, I bought some components to build up a new PC. However, I can't figure what should I do with the Power Supply. Since PSU wattage calculators are mostly inaccurate, I wanted to ask this to you people.

Here's my shopping list so far. Just need a PSU so I can start to build my new PC:

i7 4770
Asus Z87-A Mobo
Gskill RipjawsX CL10 2133Mhz 32GB (4x8)
Corsair SSD 128GB (560-535 MB/s)
My old WD 1TB HDD (will change it in a month)
Asus GTX 780 Poseidon

So.. I might buy another 780 in 6 months or so. Also, as i mentioned, I'll buy a new 1TB HDD that has a SATA3 supp etc in 2 weeks or so.

Which PSU should I go for? What should be the Wattage? (Need suggestion for both single and SLI 780s)

I would recommend that you buy a high quality unit from XFX, Seasonic,or Corsair TX/HX/AX
Here is Guru3D's power supply recommendation:
•GeForce GTX 780 - On your average system the card requires you to have a 550 Watt power supply unit.
•GeForce GTX 780 2-way SLI - On your average system the cards require you to have a 800 Watt power supply unit as minimum.
•GeForce GTX 780 3-way SLI - On your average system the cards require you to have a 1200 Watt power supply unit as minimum.

So, if GTX780 needs 550 on avg, I think I should buy something like between 750-860W right? for single GPU ofc.

Yeah I saw that after a quick investigation in forums and I bought a Seasonic X-850 80+ Gold 850W and I'm really happy atm. Even I'm not using "fanless mode (fanless until %20 load)" it's so queit. I'm in love with it atm :)  Thanks for all the replies.
