Wow. Out of all those pages, that unit you picked out is about the best there is. Not sure of what if any differences there are in the 3 750w units, the tough power Grand, dps G and the lighted RGB version, but comparatively there are what's best. Only if you bump up the size to @1000w (and about Rs. 4k more to the Corsair HXi will you get better. Go with what you prefer.
