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.

My 7950s (well some of them), are heavily undervolted, and they run fine on those adapters, but... I woudnt try to run a 5 series on them, they are power hungry bastards

Undervolted 5830 pulls about 120w? If it is 50-60w per SATA connector, then I should be fine.
Use one original PCI-E, then one SATA to PCI-E on the 5830. Also, I can always put the SATA connector on cards that run off of PCI-Ex16 slots.
Since it is NOT the cable that's the issue, but more the connector, I should be fine hooking up 2x SATA to PCI-E on the same line that came off the power supply. You know, each cable have like 3-4 SATA connections.
