Hi - just got a new ATI 4870, plugged in both 6-pin power connectors from my 750W supply (which has one 6-pin connector; for the other I used a converter on a spare molex), and hit the power-on. Nothing. The power supply does not even fire up. If I disconnect the 4870 it's all fine again.
Surely 750w is enough? I have two HDDs (one IDE, one SATA) and one IDE DVDROM, which doesn't sound excessive on a 750w supply -and in any case, even with them unplugged from the power I get the same result - it just doesn't like the gfx card.
I got hold of a nVidia GeForce 9800GX2, a beast, and had exactly the same result.
I have a Gigabyte GA-M55SLI mobo. Is there any reason that would be incompatible? These cards are pretty huge.
Would much appreciate any feedback from you guys!
Cheers, Ben Board
