As smorizio said, if it is an ATX case, then an ATX PSU will fit.
With that said, there is NOTHING that requires that PSU that will work well with that computer.
That computers motherboard in now way is going to handle crossfire/SLI well, not to mention that the cooling would be horrific and would likely damage anything that high end.
Yeah im not planing to sli but im planing to upgrade my CPU and GPU but if it will fit im ok
you sure it will fit?
No am not 100% sure it will fit because I cant physically take the old PSU out and measure what the dimensions are inside your case.
Both the Case and the PSU should both be an ATX standard but since the PSU you asked about is a high output one it might be too deep and hit against the cd rom drive.
As I was stating, this is too much PSU for any single GPU and is a complete waste of money, even if you did need a 900w PSU there is others just as good for cheaper.
You can get a top quality power supply AND A NEW CASE for cheaper then the PSU you linked.
If you are looking at any half serious GPU then that oem ASUS case is going to become a major obstacle for both cooling and fitting higher end GPUs, PSUs and coolers.
