What CPU are you running? Assuming a Hawell or Skylake i5 or i7, it will be cutting it very close. Too close for my comfort. I wouldn't do it at all on Broadwell or FX.
If you do use a 750w, make sure it's a good one that can put out its rated power, and nothing (CPU or GPUs) is overclocked. But I would still recommend going bigger to 850w.

Yeah, it's cutting it extremely close. You'd be pulling around 95-100% of your available power under full load without an overclocked GPU. When I recently built a rig for CF 390s for someone I intentionally chose an 850w just for that reason, you want a little headroom on the PSU.

That would give you a little more breathing room assuming you had a very high quality PSU. Still too close for comfort IMO.

Bisenberg :
I will take a look at 850w psu`s, if I cant afford one I use my 750w instead.
PS. I appreciate your help
It's also very important to note the qualifier "very high quality" that is included. You never told us what your power supply actually is, which is a key factor here. There's a big difference between a 750W on a dependable platform and a "750W" SuperXtremeGamerPowerMaxxx-type tin can made of junk parts that can't safely hit 450W.
