Will these parts be compatibel with each other

[Rasul-Boxer]

Im going to upgrade my p6635be with a new graphics card Asus r7 260x and a brandnew VS650 Corsair power supply. Im just worried that my motherboard (MS-7613 (Iona-GL8E)) will not be compatible. Does anyone know something about this? And will the graphics card fit in my case?

Yes, the graphics card is compatible, and yes it would fit inside.
I would, however, advise you to get a different power supply, one that is 80+ certified.
This is a good alternative:

But there is a 80 plus certification on the vs650

so what? 80+ means nothing but efficiency. you can be very efficient and still do a bad job, which is exactly the case with the VS-series

the linked CXM is way better
if you wanna save a bit, search for XFX Pro Series / TS or Seasonic S12 / S12II / M12II
