How many Watts will I need

I will be building a new computer, my first, and I would like to know approximately what wattage I should use for a power supply, and which model you guys would suggest. My specs are below

Case: Thermaltake ArmorPlus VH600BWS

LCS: Thermaltake BigWater 780e

PSU: (Current if it will be adaquate) CORSAIR CMPSU-750TX 750W ATX12V / EPS12V

Mobo: ASUS P6T Deluxe V2

CPU: Intel Core i7 920 Nehalem 2.66GHz

RAM: Kingston HyperX 3GB (3 x 1GB) 240-Pin DDR3 SDRAM DDR3 2000

Graphics: SAPPHIRE 100259-1GL Radeon HD 4870 1GB 256-bit GDDR5

HDD: Western Digital Caviar Black WD6401AALS 640GB(Will eventually get another drive, most likely solid state, when they go down)

BDROM drive: PLEXTOR Black 6X BD Combo Super Multi Drive SATA Model

I also will throw in a 15", 12", and probably 10" UV cold cathode.

If I will be good with the 750W let me know, if not recommend a PSU for me. Thanks

More about watts need
  1. 750W Corsair will be just great! You've even got the overhead to throw in a scond 4870 should it take your fancy!
  2. thats what I was planning on doing in the future, thanks a lot mi1ez
  3. Oh wow, not sure what you are have heard/seen but DO NOT GET THE TT BIGWATER!!!!. Seriously, just head over to a real WC forum (ie xtremesystems, OCfourums) and see the reviews/problems (like breaking barbs, leaking,etc) people have had with the TT water cooling kits (esp. the previous models). Save your money or invest a bit more on a custom WC set up. I personally wouldn't use a TT water cooling kit even if it was given to me; I'll probably just rip it up and salvage the pump and MAYBE the rad which will be used for cooling NB/MOSFETs, I'd rather use a heatercore than this rad that comes in the kit.
