How much power do I need and which exact model do you suggest (from Corsair I suppose)?

Also, which exact model of RAM do you suggest (also from Corsair I suppose)?

I would appreciate the exact model numbers/links!

This is my build:
Video Card: NVIDIA GeForce GTX560 Ti AMP 1 GB
CPU: Intel Core i5 2500K 3,3 GHz LGA1155
Power Supply: Corsair?
RAM: Corsair?
Hard Drive: Western Digital Caviar Black 1 TB SATA 6 Gb/s 7200 RPM 64MB
Optical Drive: Samsung SH-222AB
Motherboard: Asus P8Z68-V
Case: Not sure yet

Peripherals:
Mouse: Logitech G700
Keyboard: Razer BlackWidow Ultimate Mechanical Keyboard
Speakers: Logitech Z523 2.1
Monitor: Not sure yet.

Thanks a bunch.
 
I would go with 64bit as its the same price as 32bit, and it will give you the option to upgrade past 4gigs of ram.Corsair is not the only good reputation psu's out, theres plenty more, antec, PC Power, Silverstone, SeaSonic, XFX and a few others.As with ram, Corsair is not the only good brand here either, theres G.Skill, Mushkin, Kington, and a few others.With the prices of DDR3 ram right now, you can get 16gigs of ram for less than $100.

If your NOT going to Sli than any good 450w psu will do, if you do Sli, 600w.

Hi Savvy,

These guys here behind that link disagree with you about the 32-bit vs 64-bit and the need for more than 4gb RAM. I would very much like to hear your comments about their thoughts.

Thanks for your input!
 
If its the same price, the question is. Why not. It supports over 4gb. of memory and can run 32 and 64 bit programs.
 
64-bit is much better. I doubted it when I got it, but I have never had a problem running any game or any program due to having 64-bit. And the argument that you have to download specific drivers is irrelevant because you have to specifically download the 32-bit version, too. And when games and apps start using more than 4GB, you will be future-proof.

Tom's Hardware.

For a system with two reference clocked GeForce GTX 560 Ti graphics cards in 2-way SLI mode NVIDIA recommends a minimum 700 Watt or greater power supply with a minimum +12 Volt continuous current rating of 47 Amps or greater and with at least four 6-pin PCI-E Supplementary Power Connectors.

The Corsair Enthusiast Series TX650 V2 (CMPSU-650TXV2) power supply unit with its +12 Volt continuous current rating of 53 Amps is more than sufficient to power your system with two reference clocked GeForce GTX 560 Ti graphics cards in 2-way SLI mode.

If you run Furmark Stability Test each reference clocked card may draw up to 202 Watts (or 16.8 Amps) from the +12 Volt rail so double that for 2-way SLI. This is considered a very high non-game power consumption that can typically be reached only with stress testing applications like Furmark and OCCT.

In typical gaming each reference clocked card may draw up to 147 Watts (or 12.25 Amps) from the +12 Volt rail so double that for 2-way SLI.

Factory overclocked cards will consume more power than the reference clocked cards as expected so that also needs to be considered.

Isn't this contradictory since the minimum was 700W as you said but CORSAIR TX 650 only provides 650W?
 
The way I understand PSUs, batteries, generators, etc... is that the wattage isn't so much whats important, its the amperes. So going off what tech savvy stated, the TX650 looks to be a solid choice. If you want a little extra breathing room the TX750(60 Amp) is only $20 more from newegg if your looking at the Corsairs. :good:
