I try looking up the facts, to people posting videos and still the answer differ........ i used websites that put the information in and 3 websites gave me 3 different answers........This is what the build is made of minus the power supply as the most important so i don't buy a cheap and throw all my money away on my parts........ASUS Z97-PRO LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard.....(i'll be using 2 of the same graphics cards)EVGA 02G-P4-2966-KR GeForce GTX 960 Gaming 2GB 128-Bit GDDR5 PCI Express 3.0 HDCP Ready SLI Support SuperSC ACX 2.0+ Video Card.....Intel Core i5-4690K Devil's Canyon Quad-Core 3.5GHz LGA 1150 Desktop Processor Intel HD Graphics 4600...CORSAIR Vengeance 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model.... a case with 8 fans and will be overclocking for games and that's pretty much it oh and i have 2 hdd and 1 ssd i like to know the power supply that will be the right fit.....i was getting some calculators that said 550w and some that said 1200w... i would like to know what power supply would be best for my build so that i can put all the parts together without thinking the power supply is going to ruin them......Thanks to anyone who see this and puts an answer

This isn't readable. It's pointless to do things like this: ............................ , All the time!

- 2-Way SLI GTX 960 = Pointless. You are better off buying one GTX 970
- 2x8GB for gaming is not necessary. 2x4GB is all you need.
- You do not need 8 case fans to keep your build cool
- A 550w power supply for the GTX 970 should suffice (Put the SLI GTX 960 out of your head).

Well, the biggest power eaters are going to be the two graphics cards, at about 125 watts each so there's 250 right there. But I would agree with RCFProd, two 960's is a really silly idea. I would definitely go with a GTX 970 or even a GTX 780 Ti since I don't think having two 960's would actually be beneficial at all. You'd also save some money. Also the GTX 960 has some bad reviews.

I would disagree with his 2x4 GB recommendation though; 2x8 is great especially if you ever want to stream or run skype, internet, and more while gaming. Ram is an easy upgrade, but I wouldn't skimp on it with the system you currently have going

The rest of it is pretty standard upper end gaming hardware.

I would also recommend NOT overclocking for gaming, everything you have will run just about any game fine especially with the two GTX 960's unless you're going to try to run high end games on a 4k display.

As far as your actual question, what power supply? In my experience, 550w would be WAY too low for your system, definitely don't do that.

The 1200w would probably be overkill unless you are going to be expanding a lot in the future. I would say you could get away with a 750w maybe depending on how many hard drives you have. A safer bet would be 800w which would allow for some expand-ability, and 1000w would be very, very safe (overkill, really) and plenty for where you're at and allow a lot of expand-ability.

As far as power supplies go, I would recommend a modular Corsair power supply. Also, I'm not sure where you're from but if you're from the United States then you can give any Microcenter a call and ask for their build your own computer department (might take a few calls, they are notoriously bad at answering lol) and ask them some questions they are usually pretty helpful.
 


Edited it actually a bit after seeing your post. I always err on the higher side for PSU's for expandability reasons, but I guess that's just a personal preference. Also I'm not sure how many hard drives he's running so I thought to be on the safe side. I feel like the PSU is in the top 3 most important to think long term components.

Thanks for the advice though, I'll definitely consider highlighting the opinion side more in the future! :)
