I'm aware of the fact that one 6-pin PCI-E connector provides up to 75W, meanwhile a 8 -pin connector doubles this figure. However, the only difference between 6-pin and 8-pin connectors being two additional ground wires makes me think that a 6-pin connector is capable of supplying 150W as well.
Lately, I've been wondering, say, I have a graphics card which requires 2 6-pin PCI-E power connectors. Let's say our PSU has 2 rails, with the first one being more powerful. Unfortunately, the rail 2 (dedicated to our VGA with 2 6-pin power connectors) does not provide enough power. There're two solutions to possibly overcome this issue:
1) Leaving one 6-pin PCI-E connector of rail 2 and swapping the second one for a molex to 6-pin PCI-E adapter, plugged in rail 1. In such a case I'd have my VGA empowered by both rails, but I'd be using just one power connector of rail 2.
2) Taking both 6-pin PCI-E connectors of rail 2 and "converting" them into 8-pin PCI-E connector via an adapter. Then, taking another adapter, converting 8-pin PCI-E connector into a single 6-pin PCI-E connector. As a result, I'd have both 6-pin PCI-E connectors of rail 2 "merged" into one. Regarding the second 6-pin PCI-E connector on a VGA, let's use the same molex to 6-pin PCI-E adapter, connected to rail 1.
The question boils down to this: would I get more power to a VGA if the second option of wiring was used?
