Please log in for more thread options but I'm a little confused... There are obviously different groups of cables coming out of the PSU. Some with different connectors on them... Which is which? The reason I ask is that my GPU is supposed to run with a PSU that has 30A on the 12V rail...what exactly does this mean? is a rail one of the groups of cables that comes out of the psu? How do I know which is which? -- The Zero ST | |||||||||||||||||||||||||

Please log in for more thread options It would help if you said which PSU and GPU you are talking about. SteveH | |||||||||||||||||||||||||

I presume you have the power connectors plugged into the card? (you must have or it wouldn't work). My guess would be though, you must be close to the limit of what your PSU can do, bit difficult to say without knowing everything in the box. If you want to know which cable does what, have a look at the Chieftec website, there's probably something on there for your PSU. SteveH | |||||||||||||||||||||||||

Basically I plugged 2 molex into the card at first and it didn't work (the cables had other devices on them) So instead I found an unused cable with 3 molex on it and another smaller pin connector which was unused on the psu. I plugged 2 of the molex into the card and everything worked. I'm not sure if it was the right thing to do though...I have no idea of the power that goes to that cable (if indeed that is how a psu works - diff power for different groupings of cables) I'll have a look for a manual.... -- The Zero ST | |||||||||||||||||||||||||
