Perhaps more heat generated due to more intense processing
activity? Or the extra current draw exceeding the power supply's
ability to consistently provide?

But a 650-watt power supply really should not have such problems.
Of course, it is possible for the voltage/current on a specific
set of rails to be out of spec while the rest of the thing is
fine. A bad connection could do that. But I would not fool
around with a power supply unless I knew exactly what I was
doing, even with the thing disconnected from the mains.

Puzzling.

Interesting. I have had this Corsair CMPSU-650TX 650 watts

PFC power supply since end of 2010 when it was new. Also, why
would having video acceleration cause these rare lock ups when
having none doesn't?

Hi,

I have seen posts on AVS by a resident HTPC expert suggesting a

Might expose your problems to more experts with better advice.
