I think both that 650TX and the OCZ are going to require Molex to PCIe adapters for the 2nd card. Some people don't care but worth being aware of it. Doesn't help you save money but personally I'd opt for the 750TX. That particular OCZ unit doesn't have a great reputation.
The 5770 only requires one PCI-e connector, so either of the originally discussed PSU's have enough conncectors.
