For some context, I live in the Philippines where part selection isn't all that great (note that I only posted Amazon links for reference, as I'll be getting all my hardware from brick-and-mortar stores; online vendors aren't really an option for me due to steep customs fees and taxes for electronics over here). That said, I think the above build is pretty good, but I do have some concerns regarding the case and PSU:
1) I studied the dimensions to the best of my ability and I think everything should fit in the Fractal Design Arc Mini, but I could really use a second opinion here as this is my first build. I wouldn't mind switching to a mid tower if necessary, though smaller cases are better for me as my apartment isn't that roomy.
2) My more pressing concern is the PSU; namely, is the PSU above enough for my system? I realize the GTX 670 at minimum requires 30A on the 12V rail, and the PSU above supplies 34A. However, I'm uncertain if this is enough for the MSI 670 PE; I only ask because I heard the EVGA FTW 670 requires 38A, so it occurred to me that the MSI 670 PE may also require more amps.
3) As a follow-up to item 2--I do have a short list of alternate PSUs to use, though I want to get one that is "Haswell compatible". Topping my list would be the Antec VP550P; however, only the VP550P V2 is fully compatible, whilst the vanilla VP550P is "to be confirmed." Is there any way to determine whether a particular unit is V2 or not?
