Does everything seem alright? - and is 620watts enough?

Solution
That's a great PSU and a good choice. As a general rule, always buy the best at your budget.

Your total system will run no more than 250W before overclocking (at full power). Even if you overclock the snot out of it, the PSU is plenty, and at that price, what's the point of going smaller?
