How much power is SATA cable rated for?
I have 5830's that's undervolted, and was thinking of using SATA to PCI-E power cables.
Don't!!!It can handle no more than 5 amps so no more than 50-60W. And the connector is the problem, not the cable, the connecting surface is too small.
been running 5830s on sata->pcie power connectors for over a year. no problems.
