How much power will I need for this gaming system?

[tchan4]

Hey all, I am planning to build a new system for gaming and regular use. I have pretty much picked out everything I want except for the power supply, because I don't know how many watts I will need and which ones are good. Here are the components of my build:

CPU: Intel Core i5 3570K
Motherboard: ASUS P8Z77-V
Graphics Card: 1x EVGA GeForce GTX 670
Memory: 8GB Corsair Vengeance
Hard Drives: 250GB Samsung 840 SSD and 1TB WD Caviar Black
Cooling: Either a Cooler Master Hyper 212 EVO or a Corsair H80i
DVD Drive: Some simple Samsung drive
Case: Corsair 600T

I was looking at either the Corsair HX650, GS700, TX750M, or the Silverstone Strider Essential 700w. Thanks for reading this post!

Any of those will be enough power, but I go for one the Corsairs, the Silverstone has some mixed reviews

A reliable 550W PSU will do unless you plan to SLI later on, then you need to go with a 750W.

Alright, thanks for the awesome and quick replies! 550 watt will also save me a couple bucks hahaha
