I have a ref 480 with the usual power issues.
A hardware modder has found there are two sets of pads on the card that bridge the two power and ground planes, PCIe and the 6pin.
Acknowledging the usual caveats of voiding warranty etc.
Are there any issues that would be caused by feeding the PCIe planes from the 6 pin by bridging the pads and cutting the PCIe 12v fingers on the card connector.
The 6 pin from my power supply can feed the 480 without issue, it's a 1k supply I originally bought to power my 2 HD6070's.
