Most certainly. Maybe not on a lower powered psu but on my 950w (which isn't modular) I have at least 5 (maybe 6) extra cables even with SLI because I only have 2 hard drives and 1 optical drive. Plus I get 6 PCI-E power cables anyway.
oh, i see, it is an issue with sata and molex then as oppose to pci-e cables
