Would this power supply be enough for my gaming PC?

Yup and easily too plus that Corsair is a Seasonic built PSU = Top of the Pile.

Hx750 can even output 900w in certain scenarios.

The HX750 and HX850 and above are Channel Well Technology(CWT)
The HX650 and below are Seasonic design.
I'm referring only to the HX series.

Great, thanks!

LOL I was thinking XFX opps but we were both a bit off base only a bit but at any rate the quality is still top notch either way so no harm done thanx for pointing out my mistake instead of just burning me. http://www.realhardtechx.com/index_archivos/Page447.htm

Ok here is the De facto Specs, Review, and Data Base for all PSUs you are wondering the quality etc of so you can just get it from the horses mouth all of the spec and nitty gritty.

So where was i off base exactly?
You're right no harm done.
I make little errors all the time here!
No biggie!

AX 850,750,650 are all by Seasonic the AX1200 is the odd ball it's by Flextronics but get this the AX1200 has 1205watts on the +12v Rail FTW gotta love Corsair and how they typically underrate there PSUs a trait of supreme quality and honesty which is rare to find today. PS nobody no matter how good can remember everything 100% all the time well maybe if you are Steven Hawkings or the Internet.
