does anyone know if a CPU 8 pin power lead can be plugged into/suitable for a graphics card?
ive got a coolermaster realpower 650W (http://www.coolermaster.com/product.php?product_id=2551) and getting a radeon 6970 that requires 1x 6pin and 1x 8pin for power.
 

It is not a case of phasing but polarity. The two connectors are wired differently. Plugging either one into the wrong connector (you are not supposed to be able to do this) will result in shorting 12 volts to ground.

If you are lucky, the PSU will detect this and electronically shut itself down. If you are unlucky, you can fry the motherboard, graphics card, PSU, or possibly the CPU.
