Will a FSP RAIDER 750W hold a R9 290 Tri X CF?

My bad, didn't see that lol It'll be tight, but it would work. I would recommend buying an 850w PSU, but if you already have the 750w, it'll work. You just wouldn't have any overhead for overclocking or anything like that. That'll put you at about 650w at load, and your PSU is rated to 720 on the +12v rail.

I'm sorry, my English is not that high... I didnt understand what you ment... Why shouldnt I push a little more?
And another question... I don't want to buy the second R9 290 soon, I want to buy it only in 2 years from now or even more (when it wouldn't perform so great in games - less the HIGH) and I'll probably have the option to buy a totally new GPU...
1.Will the PSU manage to hold a new GPU in a few years?
2. Will an I5 4570 performe better with a CF of R9 290 or a totally new GPU in a few years.....?
 
It's not good to push the PSU to its limit, it will become unstable.

If you buy a totally new GPU, and use it by itself alone, your PSU will be perfectly good to use. If you buy another 290 to use in CrossFire, you will be pushing it close, and I would recommend a new PSU.

The 4570 will be great for 2-way Crossfire, but I don't know what you have now to compare the performance difference.
