Can a 300 watt PSU run with a 1.4ghz TBird? I'm getting my SX830 sometime next week and I was just wondering if I should even try to boot up with the 300 watt PSU? Could I harm any of my components by using a PSU that is too weak? I'd really hate to break something just because I was daring and tried to boot up with a 300 watt PSU. Thanks.
