View Full Version : 7800gtx sli & power supply

Doing yet more research on a sli setup. I have a Antec True Control PSU at 550watts. Will it be enough for dual 7800gtx cards? Do you need a psu with addtional connectors?

Yes, it will be enough. Best to have a unit that has two connectors. Otherwise, you will need an adaptor(s).
