Just as a note, it's a single sense pin. Norma 6 pin is 2 guaranteed +12V, a 3rd optional one ( almost always populated and used though) and 3 ground lines. The extra 2 pins on the 8-pin, introduce the sense line and a ground. The sense line does 2 jobs: 1) Tell the GPU power is definitely connected, and 2) tell the GPU if a 6-pin is there or not. In a proper 6-pin to 8-pin, that sense is never there to make sure you don't exceed the 6-pin spec, as it's up to the GPU to make use of the line and not pull the extra power. There's no should/shouldn't work here, straight up. It's part of the spec to allow them to work, but at lower power. As someone working for a HW manufacturer, I just wanted to step in and correct this.
