power 2900XT

[ijsco]

A friend of mine bought a 2900XT which has two power connectors ; one 6 pi and one 8 pin connector.
The card comes with two 6 pin to 4 (12V) pin connectors , does he has to put both connectors in even though 2 pins aren't used from the 8 pin?

Yes, the card needs both plugs to function. What PSU does your friend have? If it does not come with 6 pin PCI-e connectors it's probably not one of the newest or powerfull ones. Make sure the 12v rail has enough amps to supply the card with enough power. As for the 8-pin, these are needed when you want to OC. Asfar as I understand the card disables OC-ing from control panel if the 8 pin is not connected.

He has a Zalman ZM600-HP (600W) which has two PCI-E connectors.
The card came with the two connectors mentioned earlier.

In the link below HardOCP overclocked two cards with and without the 8 pin connector (using 6 pin). They had no differences in their overclock results other than not being able to use ATI's overdrive OC utility.

Ok well that PSU should be good enough When you mentioned those adapters I thought it meant his PSU didn't come with those. You're still gonna have to connect both of those 6 pins though or it will run out of power with demanding games.

thanks for the quick replies guys!
I did connect both but just making sure that it didn't cause any damage (I did the build)...

peace
