EVGA CPU EPS 8pin to PCIe 8pin (6+2) cables give you an extra option to provide power to your latest graphics card, and with individual sleeving these cables also look the part. Although originally designed to supplement the GM line of power supplies, these cables are also compatible with other EVGA power supplies, which can be located under the compatibility tab.


WARNING: Due to the electrical pinout of each cable and the unique electrical pinout designed for your power supply, using this cable with a non-certified or unsupported power supply may cause irreparable harm to your power supply, cable, and/or any connected devices. Use of this cable with any non-certified or unsupported EVGA power supplies or power supplies from another manufacture voids the warranty for this cable, and may void the warranty of your power supply. Furthermore, EVGA expressly disclaims any damage caused by or attributed to use of this cable with any power supplies that are not certified for use with this cable.

This product is covered under the Terms & Conditions of EVGA's Global Warranty for Accessories when used in conjunction with EVGA power supplies certified compatible for use with this cable.
 

Does the CPU connector on the PSU outputs similar/same wattage/volt/power as the VGA?  With this cable (CPU EPS), is it "safe" (to the PSU, to the graphic card, to the cable, etc.) to power another GC (7th)?  I already used up six VGAs on my GT1300W PSU.  Each GC used around 125-150W.

Thanks
