PSU for gaming rig.

[x731]

G'day.

I will be buying this system in a matter of days, and am thinking of getting a new PSU.

Currently, my rig is;

CPU: Intel Core i5 3570K 3.4Ghz (245 AUD)
CPU Cooler: CoolerMaster TPC 812 (84 AUD)
Motherboard: ASRock Z77 Extreme6 (189 AUD)
Ram: G.Skill Ares 16GB (2x8GB)
GPU: HIS Radeon HD7970 3GB IceQ X2 Turbo (559 AUD)
*PSU: Cooler Master UCP 700W (Owned)
SSD: Samsung 830 Series 128GB. (135 AUD)
HDD1:: Western Digital Caviar Black 2TB. (189 AUD)
Monitor: Samsung S24A850DWK LED PLS (309 AUD)
*Case: CoolerMaster HAF 932 (Owned)
Cooling: x3 BitFenix Spectre Pro : White LED (29 AUD ea; front, side, top), BitFenix Spectre Pro : White LED (17 AUD; back). (104 AUD total)
Other: DEMCi Flex CoolerMaster HAF 932 Filter Kit (49 AUD)

While my 700W seems fine, I am hoping to upgrade to something like a Corsair HX-850? Or something similar.
My only concern is that the cables are long enough to reach throughout my HAF case without any problems.

Cheers for any help, so far TH has been fantastic with all the help.

The cables will be long enough

I would say your current one is suffice for your system, but if money is not an issue get new one with corsair brand.
