Hello There !

my name is Angelos

I have also a Mac pro desktop 5,1
with 20 Gb ram and i want to update my graphics Card from the HD radeon 5870 to the new GTX Titan black.
I was thinking for the evga super clocked or the Gigabite version (in my country i can find easier the Gigabite version)

Here are some questions if you could answer to me.
Is there any issue with the card?
Does the card workes out of the box?
In the specifications i read that the card needs a 600W PSU and the PSU of the
mac pro desctop 5,1 is 980W if i am not wrong.
So does it really need an extra PSU for the card if you are only going to use one card?

Thanx!
