G is the better unit of the two, but you dont need 750 watts for one video card you can do with 550 watts

It says 750watt on the manufacturer site for sapphire r9 290 tri-x. If anything happens to my gpu it s out of warranty cus of i didnt use their recommendation PSU? And for u 750 W s even enough for 2x R9 290?

That recommendation is based on a peak rated PSU not a continuous rated PSU so no you dont need 750 watts for it

And yes unless you are going to overvolt the cards you can have 2x cards on a 750 watts
