The cpu will not bottleneck the card in question, the board is compatible with any pcie 3.0 card(pcie 3.0 is fully compatible with previous versions, with 2.0 16x, it won't take a hit in performance).
A 500w psu is the minimum required, you got one with 730w, but there's no mention of the brand of the psu, it's rare to see one with 730w, either it's 700 or 750.
My case actually covered most of the label on the power supply, so i can't see the model number, but it said 729W somewhere on the sticker, so i figured it was 730W. However, i'm 90% sure that it's at least 700W. I bought it from Tigerdirect if that helps.
