9800gt power problem !

when i powered my 9800gt with the 6 pin connector " which came directly from my PSU " it said

"very low power ! - forceware has degraded its performance to a low level for optimized run "

so ,

1. i shutdown my system
2. removed the 6 pin connector
3. used the "2 molex to 6 pin connector" which came with my 9800gt .
4. restarted my system
5. voila ... it runs great ...

question is " why dint it have enuf power supply when i powered my card thru the 6 pin connector which came directly from my psu" ? and how come it is working fine when i used the "molex to 6 pin connector " ???


PLS . i need to kno wut is wrong ... somebody temme the difference btw the 2 !

because 9800gt requires 2x 6pin pcie connector to run properly so when u use molex or other name of molex is converter it converts the power into 1pin that runs 9800gt in full power.
