Too much or too little or just right?

Hello and thank you, I'm building my first PC with a little help but I'm putting together the components. What I need to know is, is a Corsair Professional Series 850W SLI 80 PLUS Gold Certified Modular ATX Power Supply, Strong enough to Power ( ASUS Sabertooth Z87 Intel Z87 LGA 1150 Motherboard) ( Intel Core i7-4771 3.5GHz Processor ) ( EVGA GeForce GTX 770 4GB Dual FTW w/ EVGA ACX Cooler) ( WD Desktop Performance 2TB Internal Hard Drive ) (Samsung 250GB 2.5" SSD 840 Series x2) ( Corsair Vengeance LP 16GB (4 x 4GB) 1600MHz DDR3) (Asus 12x OEM Blu-Ray Writer) and( Logitech Gaming Keyboard G510/ w/ Logitech G600 MMO Gaming Mouse) . Will 850watts be enough or to much? Thank you for taking the time to answer.

    I think it is enough, you can try estimating how much you need with a tool like this

  2. It's enough for the rig and even gives some headroom for the future.
  3. Like varun_02 says,it will be enough and will even give the option to go for sli with the gtx 770.
    If you don't go for sli it will be to much,650watts should be enough and 550watts probably too.

    Do you already have the system looking at your question? The cpu cannot be overclocked,you know that?

  5. Thanks for answering man. Sorry took so long to respond been away from civilization for past 24 days, :} But I already did my build and it turned out great, just a couple differences from what I posted, I went with the Corsair AX 860 platinum psu,and 24GB of corsair vengeance memory and only 1 Sony ssd 250 gb. But yes to answer your question I did know that the 4771 could not be OC'd. Since this was my first build and I'm still very new to this I waas not worried about Overclocking as I learn more and gain more experience I may switch to an unlocked processor in the future.
