How much watts?

[R3ZAA]

Hey guys I'm planning on building a PC with these specs:

CASE: CoolerMaster Storm Enforcer

MOBO: Gigabyte GA-Z77X-UD3H-WB WIFI Motherboard

CPU: Intel i7-3770k

GPU: Sapphire 2GB 7850 OC

Optic Drive: LG GH24NS90 24x SATA DVD-RW Drive OEM

HDD: Seagate 3.5" Barracuda 2TB ST2000DM001

SSD: Intel 330 Series 120GB SSD

RAM: G.Skill Ripjaws X F3-1600C9D-16GXM 16GB

CPU COOLER: CoolerMaster Hyper 212 EVO

Card/R: Shintaro Internal Card Reader 3.5"

I wanted to know if I should get a 750w or 850w power supply for this setup? I will be doing Xfire with the 7850, overclocking the CPU and maybe GPU, and also a water cooling system.

Thanks a lot!

Water cooler running off of a 110V plug like your computer or the 12V PSU in your computer?

77W CPU + 260 for the GPUs + 50W for other stuff ~ 500W. Depending on how high/aggressive you are on your OCs you could be looking at 600-650W. 750W will do fine, more if your water pump runs off of the computers PSU. How much more will depend on the pump.

The water cooling system is just a maybe, I don't really need it though so pretend I'm not getting it.
I probably wont OC too high so I'm going to assume the 750w should do the job perfectly!
Thanks
