Re: Is a 600W PS big enough for two 8800GTS cards?
While we're on the topic of the OCZ stealthXstream's power capabilities... could it run a 9800GTX+? I'm just wondering because although its combined amperage rating is 72 (18 amps per 12V rail), all of its PCIe connectors are on one of the +12V 18amp rails. The card mentioned requires 26 I think, which the PSU can achieve if the amps combine. I'm really confused here.
Sorry if this hijacks your topic, but I think this will answer questions for both of us. |

The 600W StealthXStream shouldn't have any issues running a pair of GTX+ cards. |
