Recommend me enough wattage please...

Here's the setup (with part links)...

Mobo: GIGABYTE GA-Z68A-D3H-B3 LGA 1155 Intel
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128502

Processor: Intel i5 2500k S.B. 3.3ghz
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115072

GPU (x2): EVGA GeFocre GTX 560Ti, 448 Cores, 1.2Gb.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130739

Memory: Corsair Vengeance 8Gb, DDR3 1600 (2x4Gb sticks)
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145345

HDD: Seagate 1Tb 7200rpm
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148321

SSD: Crucial M4 64Gb
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148441

Optical: Asus Combo (Blu-Ray/DVD/CD)
http://www.newegg.com/Product/Product.aspx?Item=N82E16827135252

Misc: Rosewill 74 in 1 Multi card reader
http://www.newegg.com/Product/Product.aspx?Item=N82E16820223113

Other Stuff: Razer Mouse/Keyboard (both blue LED), 5-6 LED case fans, Cooler Master Hyper 212 EVO heatsink/fan. I may also double my memory to 16Gb (same memory obviously), may overclock processor to 4.0ghz, and I'll be using an SLI set-up with two GPU's.

Other notes: I was originally looking at an 80+ Gold 850w PSU, but wasn't sure if I should go for something more for longevity. Basically, I wouldn't mind spending the extra $50 on a good 1000w+ PSU if this setup seemed like it would benefit from it. I've never ran an overclocked pc with SLI before, so I'm not sure what size PSU I should start at.


Any suggestions on what size PSU I should go for to safely run this system, preferably one that would last awhile? Thanks in advance, and sorry such a long post.

This should be enough and is 80+ platinum http://www.newegg.com/Product/Product.aspx?Item=N82E16817151111
If you want 1000W this is very good : http://www.newegg.com/Product/Product.aspx?Item=N82E16817341045
and another 80+ platinum : http://www.newegg.com/Product/Product.aspx?Item=N82E16817151105

GTX 560 TI 448 Cores use slightly less than GTX 570s, so I would use a GTX 570 SLI review's power consumption figures to figure out your likely maximum power consumption.

The only such review I can find which I 'trust' is from Guru3D
http://www.guru3d.com/article/geforce-gtx-570-sli-review/13
They shows a system using an i7-965 (much more power hungry than any Sandy Bridge CPU) using 578W at the wall. Take 10-20% off that number to get an idea of what their system actually drew.

The other way to figure out how much your system will draw is to find out how much GTX 560 TI 448 Core's draw and then add the rest of the system to that.

It is generally agreed that 850W is plenty for systems with two GTX 570s, even by people who always go overkill. Getting a 1000W PSU will only give you any appreciable longevity if you ever want to upgrade to monster cards like two GTX 580s.

You should change the memory to something without tall heatspreaders, as they are unnecessary on DDR3 and they will just interfere with CPU coolers.

Is there some reason you need a retail HDD? As the cables etc that you need come with other hardware like the motherboard, case or PSU.
What case are you getting (or have already) btw?

a good 650w is enough for a single gtx 560ti 448 and a 850w is enough for SLi.
here's a good 650w-

and a 850w-

That's the hard drive I was recommended, wanted at least 1Tb because I do photography and editing occasionally with my wife who's a professional photographer. Should I look at something else? I haven't ordered the hard drive or SSD yet. As far as cases, I'm currently using the black Dragon Rider case from In Win (http://www.newegg.com/Product/Product.aspx?Item=N82E16811108376).

You could save ~$50 by getting an OEM drive:
Seagate Barracuda ST31000524AS 1TB 7200 RPM $125
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148697
The drivers and utilities which are on the disc that comes with the ST310005N1A1AS-RK can just be downloaded from the internet/Seagate's website. So you should really only go with the retail drive if you can't download these things or if the extra warranty is worth the extra money to you.

Sounds good to me, thanks for the tip!

For a system using two GeForce GTX 560 Ti 448 Cores graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater power supply that has a combined +12 Volt continuous current rating of 60 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.
