It's a 'LEADTEK GF PX6600GT TDH RT' with a geforce 6600GT. Just one video card.
The AMD CPU takes up 125W. I have not connected anything else (hard/DVD drive, etc).
Here is a related data point I found for this motherboard:
Power consumption will vary depending upon the hardware and upon the PC load.
The current consumption of the test PC with AMD Phenom II 710 X3 CPU, 4GB DDR3-1333 memory, hard disk drive and Cooler Master Silent Pro M 600W test PSU was without overclocking depending upon load:
- With Sapphire HD6870 video card the power consumption was between 111W and 227 Watt.
- With Sapphire HD4870 video card the power consumption was between 162W and 237 Watt.
Fair point. Guess the fact that the fans still run with the 8pin connector out would suggest a problem with the CPU or associated circuitry,and the only way to prove that would be to try another CPU. A very uncommon fault, I imagine, not met one like it, except when my young son bent some pins on the CPU, couldn't wait for me to get home... Presume your vendor will just replace both items and you'll never know exactly what was at fault, but if you do find out, post the result...
