kenable 8 Pin PCI Express PCIe Power Cable from Dual 4 Pin Molex LP4 Adapter

Product Information

I'm not sure which brand the PCIe cable is, but it's written 18AWG. Do I really need a 16 AWG? If so, I guess i'll have to buy a new Power Supply since I can't seem to find a new cable. Here's a much bigger/better picture of them taken from the computer hardware chart done by Sonic840 on Deviantart ( CC BY-SA)

The PCI-e limitation of 150 watts is chosen to allow 2 8 pin connectors on a single cable coming from power supply - keep in mind that there's ONE connector plugged into the power supply, usually with 3 or 4 pairs of 12v wires which are then shared between those 2 connectors. So, 2 x 150w max = 300w max, which is within the reasonably safety limits of the connectors on the power supply end (if the power supply is modular)It is very common to find cable with dual connectors but not an Y cable, instead you get the second connector extended (daisy chained) from the first one.

Also, since my new GPU require 2x 8pins, I've also heard that you should use 1 power cable for each 8pins for even power. Is that true? You can have pci-e 8 pin to 2 x pci-e 8 pin adapters - these would be your best bet. You know the input can take nearly 300w and then you have 2 8 pin connectors, so lots of wires between the input and output.You can't connect male PCI-E 8-pin to EPS-12V because 2 male pins on PCI-E as the top edge joined together and the corresponding pins on PCI-E does not have a slit for that. Yeah, this image was posted by Seasonic, because their older units shipped with inadequate cables which couldn't handle daisy chained 8 pins. So in theory, an pci-e 8 pin connector that has 3 pairs of wires carrying 12v to the video card could deliver safely around 9A through each pair. This means you could do up to 12v x 3 pairs x 9A = 324 watts.
