It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

Could be your motherboard's power limitations. 300 watts is a pretty standard maximum for a total of 4 PCI-e slots.
Or short circuiting the upper left pcie pin to the second last on the bottom right (emulating VGA detection)

Going beyond that, you may need to use one of those risers with a Molex feeding power to the card instead of the PCI-e slot.
Cablesaurus sells those.

If you had included your motherboard model number i could have compared it to this list albiet it's far from complete
https://bitcointalk.org/index.php?topic=36061.0

some motherboards do require that pin be shorted if you have not yet you should. Also as jack mentioned a powered riser cable is usually a safe choice here due to concerns with power draw through the motherboard.

If you found that funny or something i said useful i always appreciate spare change
