Well the topic name says it all. I need a good psu for my new build i want to get an 850w psu but im not sure if that's a good comfortable wattage. I have all stuff for my computer but don't have the psu. And i know its one of the main things you dont want to go cheap on. Here is my Specs:

Case: COOLER MASTER HAF X RC-942-KKN1
Motherboard: ASUS Maximus V EXTREME
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz......I plan on overclocking the CPU to 4.0 GHz
CPU Cooling: CORSAIR Hydro Series H100
Graphics card: SLI ASUS GTX680-DC2-4GD5 GeForce GTX 680 4GB
RAM: CORSAIR Dominator Platinum 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133
Hard drive: Western Digital RE WD4001FYYG 4TB 7200 RPM 32MB Cache SAS 6Gb/s
SSD: Corsair Force Series GS CSSD-F360GBGS-BK 2.5" 360GB SATA III
 
I plugged those details into the eXtreme Power Supply Calculator Pro, guessing that you'd need at most 1.35 Vcore to reach 4.0 GHz (though obviously that can't be known ahead of time), and got a recommended psu wattage of 562, with 41.0 A on the +12v rail. 850W will be more than enough, as long as you get a good brand.
