I've just started pulling the trigger on parts for my very first build and would like to seek a little reassurance that I've chosen a sufficient PSU for my first system before I go ahead and buy it. It must be an SFX PSU and fully modular as I'm building in a mini-ITX case, and I have no plans to overclock (even though I've included the OCable version of the GPU in my list, as it seems to be cheaper than the non-OC'd!)
I've been recommended Corsair's units in preference over Silverstone's offerings and they offer either a 450W (chosen below) or 600W unit. PCPartpicker rates my build at 280W and the Cooler Master site calculator estimated 290W, so I think I should be fine...still, it would just be really good to get some confirmation from those more experienced in the field on such an important part of the build!
