This may be a stupid question, but I do find this very confusing.
On the Sapphire website, to use a HD4890, you need at least 500w PSU and 2x 75w 6 pin PCI-E connectors.
The power supply I was thinking of buying is a Corsair TX 650W. However, it lists that is has "PCI-E 8 pin x2".
Will this PSU work with this card?
I apologise if this is a daft question, I'm a total n00b when it comes to this stuff.
