That power supply is fine. It's slightly more than you need, but there are no better options, at 550w, on your local partpicker, that I would recommend, so stick with that. You don't state exactly what you are using for photo work. Note that, if Adobe, particularly CS, it is optimised for nVidia graphics, and uses CUDA, for graphic acceleration. That doesn't mean Radeon cards won't work, but nVidia can perform better, in some processes.
Are there no more issues with this build? is the ram good? I changed it a bit: http://pcpartpicker.com/nz/p/jLOO
Thankyou for help with power supply
