Hi, my friend just got his brand new HD 3870 X2, we installed it, and as soon as we switched on the PC there was an intermittent beep from the case, and on the monitor appeared a dooming "you did not connect the power cable to your video card".
Now he got a:
ASUS P5K
Core2Duo E6750
2Gb DDr2 PC6400 OCZ
3x HD
Sound Blaster Audigy 2
everything powered by an Enermax 535W (18A on 12V)
we connected the video card with 2 6-pin pcie power cables.
So we thought it could have been the PSU, so we tried with my Cooler Master Real Power M520, (19A on 12V) that has an 8-pin pcie power cable, so we connected the 6- and the 8- pin cable to video card, and switched on the PC, but same message, same beep.
So we've got a Cooler Master 850W 80plus (28A on 2 12V, 18A on the other 2) (that has been used for some online reviews of the video card, so it should definitely work).... but we get the same message and the same beep.
Now I can only think of 2 things:
1> The video card is broken (and we have to find out soon)
2> The power multiplug (don't know how u call it in UK) that he's using can't give enough power for the PC, the monitor, the DSL Hag and the 5.1 speakers.
Please help us out!
