Advice/Suggestion for my gaming type custom builds (non-overclock)

[vegito1991]

Recently i planning to get a custom build (non-overclocking) with budget of 1600 SGD, which is around 1250 USD.
I already had my computer peripherals such as corsair k70 rgb, razer headset and mouse, and 1080p monitor, so all of these will be excluded from my budget.

For your Information

FRACTAL DESIGN R4 BLACK WINDOW - 149 SGD / 119 USD
Crucial MX100 256gb - 159 SGD / 127 USD
MSI GTX 960 2GB GAMING - 359 SGD / 287 USD
MSI Z97S SLI Krait Edition + i5 4590 - 458 SGD / 366 USD
G.Skill RIPKAWS-X 1600MHz CL9 2X4gb dual channel - 115 SGD / 91 USD
WD Blue 7200RPm 1tb - 74 SGD / 59 USD

SEASONIC G SERIES 650W MODULAR - 145 SGD / 115 USD
or
SEASONIC m12ii-modular 750w - 135 sgd / 107 USD (SLI build of gtx 970 or below for the future, just forget about 980)

Which PSU above should i go for? or is there any other recommendation to get a better psu that the price close to seasonic g series 650w or below?

Is there any improvements for my current build to get better performance in terms of gaming?

PS: If you wonder why the product so expensive compare to other place?...well...because taxes over here (singapore) is kinda high...

PS2: If anyone asking why getting gtx960, all i can say is i am not demand of ultra quality gaming on 2k above, my current laptop equipped with i5 3210 with gt 630m but able to play metro last light and crysis 3 with low settings, and i satisfied with it.

PS3: why not amd? because i much familiar with nvidia graphic settings to increase my gaming performance, so i prefer nvidia graphic card.

I would get the 650w psu. Should be able to run 2 gtx 960s. Try to get a k cpu too and maybe a cooler.
rest looks fine to me.
