[Harold Hartley]

When I’ve bought motherboards before, the manual are no help at all. I end up searching the web.

Last 2 mobo's and gpu's I've had to fiddle with both 6 or 8 pin to make work on my gpu/mobo, once it works I rather forget being few/far between and curse having to fiddle in the first place.

Expect the pcie power to fail/glitch/piss-you-off - use external power supply, and a beefy psu at that for any/all that gpu of power.

That might be a good check. make sure you don't have a connector not connected on your GPU. and/or try power on without a GPU connected. (if there is no video at least you will get power up and beeps.
