Example below, when using a GPU card that has a maximum power consumption of 300 Watt. It has an 8-pin and 6-pin power connectors.
Number of Pins
Watt
6 pin connector
provides 75 Watts
8 pin connector
provides 150 Watts
To provide additional power, you need two 6+2pin cable connectors, see Figure A.
Note:300 Watt power needed = 75 Watt from PCIe slot + 75 Watt from 6-pin + 150 Watt from 8-pin.
Figure B shows the wrong power cable to use due to special keying on the eight-pin connector. The GPU power connector has a different
keying to prevent interchanging with the +12 V power connectors.
NOTE: We do not provide different aux power cables (i.e. 8pin to 4pin Molex) other than what we offer. If your PCIe card requires a different
power adapter or aux power cable, you would have to buy it from other electronic stores.
