Power Supply Selection

[gsaxena123]

Hi,
I want to migrate to a good branded PSU, from a generic one and have shortlisted 4 PSUs.

1. Seasonic M12II 750W(the latest gen is not available for shipping to India)( http://goo.gl/ioHHXV ) about $159

2. Corsair CS750M ( http://goo.gl/YF4CEu ) about $125

3. Cooler Master V750 Semi Modular ( http://goo.gl/tVTbH9 ) about $153

4. EVGA Supernova G2 750 ( http://goo.gl/awICOl ) about $183

all the cost is inclusive of shipping and import tax. Max budget $190 including everything

I am from India and would be ordering from Amazon.com (No other online retailer). I have contacted with all the PSU companies (sans corsair) and they provide global warranty.
Out of these only for EVGA if I encounter any problems i'll have to send the PSU to Taiwan for RMA process, whereas the for other 3 i'll have to send PSU somewhere in India only if I encountered any problem.

My question
1. Should I take the risk an go with EVGA?

2. Removing EVGA from the equation which PSU should I go for?

3. Is 750W going to be enough for future upgrades including xfire/sli?

Current Specifications
i5 3450 3.1Ghz
12GB DD3 1333MHz Ram
Intel DH67CL
AMD HD 5770 (going to upgrade soon)
1TB 5400RPM HDD (gonna add SSD and or HDD soon)
Gonna upgrade CPU and MOBO in 1-2yrs

Seasonic is what I'd chose followed by the EVGA.

Hope that helped
