Graphics card + PSU question

post #1 of 9
Thread Starter 
So does a 6600gt need its own rail? If it can share a rail what can it share with? The HD? Fans?

i think the 6600gt would be fine on any of the rails... but if u have a spare one or can easily give it its own....y not do it.

I just did because I got a message saying it wasn't getting enough power. Tested the rail with a multi meter at that time and It was fine.

Well, the 6600GT doesn't have an external power connector, so I'm guessing that the case fans attached to your motherboard's 3-pin connectors could be siphoning off power from the 6600GT. Try connecting the case fans to a different power source (maybe a 3-pin to 4-pin molex converter if you have one), or getting a new PSU altogether. That's all I can think of.

The 6600gt AGP does have an external power connector though.

AGP 6600GTs do have external power connectors because the AGP slot can only provide 45 watts of power compared to the 85 of PCI-E, so PCI-E 6600GTs don't need external power.
