This is the new build I plan on buying next week:
I need a PSU to back up this entire system and SLI of the GPU in the future:

1) GPU: Asus Nvidia Geforce 670GTX DC2T

2) CPU: Intel Core i7 3770K 3.5Ghz s 1155 8MB, GPU Core (box)

3) Motherboard: Asus Sabertooth Z77

4) Case: Corsair CC600TWM-WHT Graphite Special Edition

5) PSU: Corsair CMPSU-750AXEU Gold AX750 Modular (still to be decided - might take the HX750Wat)

6) RAM: 2X8GB G.Skill Ripjaw-X DDR3 1600Mhz

7) CPU cooler: Noctua NH-D14

8)SSD: Crucial Solid Series 256GB CT256M4SSD2 SSD

Now I don't know what Power Supplier I need to support such a build, I want to have the option to go SLI in the future !!!
Can you please recommend me the amount of Wat needed, the best most reliable model and manufacturer?
(note: I might buy an HDD+128 GB SSD instead, not sure whats best for gaming)

Thanks alot.

Here is Guru3D's power supply recommendation:


GeForce GTX 670 - On your average system the card requires you to have a 500~550 Watt power supply unit.
GeForce GTX 670 2x SLI - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
GeForce GTX 670 3x SLI - On your average system the cards require you to have a 850 Watt power supply unit as minimum.
Remember, if you are going to overclock the GPUs or processor, then we do recommend you purchase something with some more stamina. The minute you touch voltages on the CPU or GPUs, the power draw can rise real fast and extensively.

Why do you recommend the Corsiar HX750W over the AX?
Is the HX modular?

Also, I don't think that with such a strong build I will ever need SLI for any game out there, but I just want to be future proof.
What do you think?

Oh and I already bought the Asus 670GTX DC2T (TOP) card, I read many fantastic reviews about it, it's a quality card they say.

I just recommended the HX because it's cheaper and will do the job the AX is fine as well and i don't think you need SLI now but in two years i am sure it wouldn't hurt ;)

I'm from Israel. Prices are higher here by a great deal.
Still, I want to buy quality parts, and I want to have good airflow and temptures inside my case.

I will take the HX if its so highly recommeded, I heard its "Half Modular" is it true? shops here doesn't indicate its modular.. but newegg says it has modular cable design..
I really prefer my PSU to be modular, it's a high end build, I rather go high end all the way with such investment.

Someone recommended me strongly against TX, since it has messy cables and no modular choices.

Also any comments about the rest of my build or Case in specific?

The GPU yes, mainly the Memory clock.
And are you sure I should get HX instead of AX? modular is very important for me, whats the difference?
