Re: Upgrading Power supply?
Yha, save your money.
While its only 450W Corsairs have excellent Amps, and quality components.
You don't need a new psu yet.
Unless youre running huge resolutions, single cards are just dandy, and 2 cards are barely noticable.
Youre issue is most likely gpu or monitor. I'd borrow a monitor and try that out anbd eliminate the screen.
Heat issue would usually lag out first as iut down clocked, then locked up, but lie baron said, check your temps with gpu-z or riva tuner or ati tools.
On that Antec Calculator... Its a little low, as my sli system oc'd reports only 500W... Which is kind low.. The other version of that calculator gave e a 800ish Watts..
