A: 750 watts is fine.the card draws about 350 watts under load.and the rest of an average system is about 250 watts.
Q: What is the total length with the Z support bracket?
A: The length of this card with the Z support bar installed is roughly ~377mm in length. I'd just round up to 380mm just to give yourself a bit of extra room to work with.
Q: there is another merc 310 on best buy, why is this one cheaper?
A: Same GPU but different clocks. Interestingly enough, the cheaper of the 2 SKUs at the moment of writing is the black edition with slightly higher clocks so there's a win there. Also, something to note is that the black edition has a silver backplate which is a little funny =)
