My first pc build!

So i decided on these parts:

Mobo.Asrck 990fx extreme 3

cpu.AMD FX8350

RAM.DDR3 Kingston HyperX Black Series KHX16C9B1BK2/8X 1600MHz Kit 8GB (2x4GB) CL9 9-9-9 XMP

CASE.Aerocool Templarius Telum

PSU.Aerocool Templarius imperator 1150w

VGA.Sapphire R9 280X VAPOR X

HDD. 3.5" Western Digital Caviar Blu 1TB 7200RPM 64MB SATA3

My problem is that on the Asrock site the ram and the cpu that i chose are not listed as compatible with the mobo itself.So i did a little research and it seems that a lot of people used the same mobo,cpu and ram i chose and have no problems.So i'm a little confused,Please help!Btw i intend to use this build as a gaming pc and do not want to overclock right now as a i am a newbie.Sorry for my spelling English is not my first language.

Dude as far as i can see the RAM and the CPU are compatible. 

Just another thing 1150w is a total over kill bro. I would recommend a 800w it would still be alot but you'll be able to do more if you want. Plus Aerocool is a good brand but with all of the money that u save with buying a 800w PSU try and buy a Corsair, Seasonic, Cooler Master. Just some tips hope that helped mate.

Good build. PSU is overkill. Get a 750 or 850 80Plus Platinum Seasonic. Or maybe a corsair RM. Anyway good to go.  

Thanks for the answer! On the psu issue i found it real cheap like 100€ since i live in Europe,and i'm planning on adding another vga in the future,and the recommended power for crossfire on sapphire's site is 1000w or higher!!Just for one they recommend a 750w or more.
