So i know this is a lot like the other post, but i still cant seem to fix mine. Everythings brand new, but when i power up, no signal. Im thinking this could be if the 2 power sockets to the video card are wrong? the psu is modular which kind of confused me.
the psu has both 6 and 8 pin 12v3 and 12v4. ive tried all combinations of them, right now ive got both plugged into the 12v4, the 6 and 8 pin. With any other combination the fan on the 4870x2 doesnt run. But ive still got the 3 red lights and no signal
