Hey there people,

I was wondering if 650w would be enough for my build because in Australia there is a Corsair Hx-650 for 130$ and then there is a Corsair Hx-750 for 190$.... WHAT!!! ONE-HUNDRED-AND-NINETY-DOLLARS!!!! So im wondering If the Hx-650 would be enough?

CPU: Intel i7 3770K
GPU: Gigabyte Radeon HD 7970 Overclocked 3GB
HDD: 1TB Western Digital Caviar Black
OPTICAL DRIVE: Pioneer DVR-220LBKS
MOTHERBOARD: Gigabyte GA-Z77X-UD3H
POWER SUPPLY: ?????????
RAM/MEMORY: G.skill Ripjaws-X 1600Mhz (2x4GB)
OS: Windows 7 Home Premium 64-bit OEM
Cooler: Cooler Master Hyper 212 EVO

Also would you reccomend the 650w or the hx-850 for 215$?
Or do you know a better PSU that is 750w?

An overclocked 7970 may at times pull a maximum of 340W

The rest of the system will not pull 200W.

So really a good 550W will do.

So I understand that the Hx-650 is good for my needs but I think the corsair Tx-750 is my kind of deal
