Hi, I'm building a computer for gaming/video editing/3D modeling and I'm stuck on what PSU I should use since I'm a bit unsure on wattage and all that. Is the SeaSonic X Series 850W 80+ Gold Certified Fully-Modular ATX Power Supply any good, or is 850W too much? Should I stick with 750W?

This is my build:

Asus Maximus VI Hero ATX LGA1150 Motherboard
Intel Core i7-4770K 3.5GHz Quad-Core Processor
EVGA GeForce GTX 780 3GB Superclocked Video Card x 2 or 780ti x1
Corsair H100i 77.0 CFM Liquid CPU Cooler
Western Digital 3 TB SATA III 7200 RPM
Samsung 840 Pro Series 256GB 2.5" Solid State Disk
LG BH16NS40 Blu-Ray/DVD/CD Writer
G.SKILL TridentX 16GB (2x 8GB) DDR3 2400MHz

If you want to add 2 Super-clocked 780 GTXcards then you would need a 850W to stay safe.

If you want to get only 1 GTX 780ti then 750 would be fine.

850 watts is recommended for dual GTX 780 Ti cards in Sli.

Don't use a budget model in a high end system. The best deal I see is this XFX. Like all XFX units it's made by Seasonic ( the best ) and is based on the high end Seasonic X series. 80 Plus Gold certified and fully modular.
