Power Supply Connections for SLI
I have this power supply http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CJsBEBYwAA&url=http%3A%2F%2Fwww.newegg.com%2FProduct%2FProduct.aspx%3FItem%3DN82E16817371020&ei=r4GoT7ilEoSQ9QSLiZCVAw&usg=AFQjCNHuRa2disLZ67hE-mUIDwKgvZag4A&sig2=on_8lJAjSC8v1dx32O6MYg. It says it has a 6 pin, and a 6+2 pin connection. Well mine seems to have a 6+2 connection and a 8 pin connection. I am trying to SLI my 9800 GTX+ woth a GTS 250. Is there a way to make the 8 pin fit in the 6 pin connection of the GTS 250, or do I need to get an adapter or modular connection?

EDIT: Fixed the PS link.

Typically a 6+2 power connection means that the 2 pins that enabled the 8pin connection can separate from the 6pin, I would check to confirm this. I rarely see PSU's with solid 8pin connections.

As for SLI'ing those two cards it is highly unlikely it will work due to SLI compatibility restrictions:

They are both 512mb cards so they will SLI together.

I know, it surprised me too. One connector has the 6 with removable 2. It says PCI-E on it. The other connector is a solid 8 pin connector that is unlabled.

Are you sure the solid 8-pin connector is'nt a 8-pin cpu connector instead of pcie?

Very seldom are the aux pcie connector's solid but are the 6+2 pin instead.Several mfg. have started putting the 6+2 pin and the 6 pin pcie connector on the same lead so you might want to check that.

Their is several psu's on the page you linked too so i don't exactly which one you have.

Wow I think I figured it out. It appears the second 6 pin cable was a modular cable that was missing when I got the PS. Looks like I will have to contact Antec.

That is probably the 8 pin CPU power connection and not intended to be for a video card.

well, now the question that you should do to yourself is "are only 550W enough for 2 cards?"

I wouldn't say more than enough... probably more like barely enough.
