One PS cable for six devices??

I’m building a new system using a Corsair CX750M power supply. For the sake of simplifying the cabling inside my small mid-tower case, I’d like to power all the HDD and optical drives, a USB 3.0 card and USB 2.0 front-panel hub off of one SATA modular cable.



I’m not sure if the single modular cable can handle all the load of two SATA HDD’s, two SATA Optical Drives, one powered USB3 PCI-e card and one powered USB2 front-panel hub. Of course, I’d have to use a couple of short adapter cables. The cabling, starting from the SATA power connector at the end and furthest from the power supply, would be:



First SATA Connector - (1) SATA Optical drive - 5v @ 1.5A & 12v @ 1.5A & (1) SATA

Optical drive – 5v @ 1.7A & 12v @ 1.9A both on a SATA male x (2) SATA female adapter.



Second SATA Connector - (1) USB 2.0 front panel hub – assume 5v @ 500mA each port x 4 ports = 5v @ 2000mA (2.0A) maximum & (1) PCI-e x1 USB 3.0 card – 5v @ 900mAh each port x 4 ports = 5v @ 3600mAh (3.6A) maximum both on a SATA male x Molex and FDP female adapter



Third SATA Connector - (1) SATA HDD – 5v @ 0.75A & 12v @ 0.75A



Fourth SATA Connector - (1) SATA HDD – 5v @ 0.75A & 12v @ 0.75A



Eliminating just one power cable from the power supply would make a big difference in this case. The only other cables from the PS would be the typical ATX motherboard power connectors and one PCI-e video card 6-pin power connector. Am I overloading this one power cable or maybe one side of the PSU?
