That looks promising. 66W to 25W is a hefty power cut though, and depending on how the power phases on the card are physically connected could result in odd issues if one/two phases are only putting out a quarter of what the other phases are.I stumbled on this article and it made me think of the 25W PCIe slot issue :
Following their BIOS mod guide, do you think you could lower the PCI-E slot power value to 25W and balance the extra power onto the PCI-E 1 value ?
If such a mod could work, you wouldn't need a powered riser, provided you have GPU with a PEG connector.
I happen to have a PEG-equiped 750 Ti to test such a setup.
