Hey guys. I'm building a PC and was wondering about PSUs. I am building with a NZXT Phantom so I was thinking of getting a NZXT HALE90 V2. But I am curious on what version I should purchase. The 850W, the 1000W, or the 1200W.

My Rig.
Windows 7
-Intel DZ77GA-70K MoBo
-Intel Core i7 3770K with a CoolerMaster Hyper 212 EVO
-ASI GeForce GTX N770 Lightning witch I plan to SLI 2-way in the future.
-2 SSDs totaling about 300GB
-WD Caviar Black 2TB
-2 140MM fans, and 2 200MM fans.

I have absolutely no idea what kind of wattage I need and I could use some assistance.

You should be fine with the 850. I'm pulling similar power to your setup, only I'm using several more fans & mine is running smooth.

Asus Sabertooth X79
Intel I7 3820
COOLER MASTER Eisberg 240L Prestige Closed Loop Liquid Cooler
32GB GSkill Ripjawz DDR3 1600 1.5v
2X EVGA GTX 770s
WD Caviar Black 1.5TB
Seagate Barracuda 1.5TB
Seagate Barracuda 300GB
Asus DVDRW
8x 120mm case fans
1X 200mm Top Fan
Antec CP850 850w PSU

For a system using two GeForce GTX 770 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 62 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

A reputable name brand 750 Watt PSU is sufficient if you're not planning on doing any overclocking of the CPU and/or GPUs. Choose an 850 Watt PSU if you are planning on overclocking.

If you won't go over 20% OC and only do a 2-way SLI, 850~ should be nice.
Just make sure it is a HIGH QUALITY one, made by a known company such as: XFX, SeaSonic, Corsair, Cooler Master or OCZ.

My suggestions:
XFX Pro 850W Black Edition
129.99$ - 15$ Rebate = TOTAL: 114.99$
OR
Corsair HX850
169.99$ - 20$ Rebate - 20$ Promo Code: EMCXMVN49 = TOTAL: 129.99$

They are both cheaper and better than the NZXT you thought about buying.
I would personally go for the XFX just because of the $ difference.

Good luck,
Omga4000 :)
