Since the 5830 uses ~175W and the PSU can deliver 498W on the 12v rail, all is just fine as the complete system draws ~325W. Even with overclocking the total 12v rail draw should be less than 450W.

The 5830 is a <150W card wink.gif

ATI says TDP up to 175W per the link given. Either way the PSU is more than adequate.

Excuse my bluntness but do you know what TDP is and what it refers to?..
His system pulls below 250W at full load from a PSU that's designed to provide 500W continuously(600W with proper case airflow).. he'll need a couple more 5830s to actually take advantage of what that PSU has to offer..

His concern was keeping the power consumption below 500W which will be the case with his hardware.
