6-pin PCIe to 2x6+2pin PCIe adapter

If a video card can get enough power through the 6pin PCIe cable, then why do they even have video cards with 8pin PCIe ports on them?

@#^%@&^ I'm using a free WIFI connection right now and periodically the page refreshes to an ad with a "click to continue." Everytime that happens when I'm replying, I lose my reply. So, here's the short, short version of my original reply:

PCIe connectors have power ratings. Sure, you can go above it, but graphics card manufacturers tend to follow established standards (though I know of one XFX card that does not, requiring 5v through a PCIe connector 😕 ). The 6 pin PCIe connector is only rated for 75W while the 8 pin 150W. Pushing more power through them will cause them to heat up. It may or may not cause a problem.

I'm using two of those power splitters with no ill effects. Powering 4 9600GSOs (takes 6-pin PCI-E), on an Antec EarthWatts 650W PSU (has 6-pin PCI-E and 6+2-pin PCI-E).

I see. How much power does the PCIe 2.0 slot provide? And how much does the PCIe 1.0 slot provide?

BTW, when that happens, I find that what works pretty well is to type up your post in notepad, then when it's finished, you can just copy and paste 😉

Alternately just copy the post before clicking on Reply.

I think 150W and 75W, though I'm not sure any products have been built to take advantage of that, probably for compatibility sake. Anyone remember putting old AGP 2X cards into 8X slots and killing the slot due to voltage differences?

If the 6 pin is 75w, how can adding 2 grounds jump it to 150w or are there internal differences?
