I can't speak for the GTX (other screenshots I've seen had no problem, but you may want to get photographic confirmation) but I have the 610 as my PSU in my build and it fits no problem.*snip*
EDIT: Denki is right. The A05 really has quite a bit of room to work. The thing to remember is that it's really no shorter than a normal mid-tower case, it's just not as tall. The length from front to back is similar to anything you'd find so long cards and assorted other components should fit no problem. All you're really sacrificing is extra bay space, but if you're like me and don't use it anyway, that's not necessarily a bad thing.
