GTX 285 Power Complication

post #1 of 10
Thread Starter 
Ok basicallys i want to run my two GTX 285's in sli.

My PSU has two 8 pin connectors, however the cards both have 2x6 pins.

I can connect one cards via a 6 pin and 4 pin molex converter.

The other card however, i only have the 8 pins for.

Now i was told that i could put the 8 pins into the 6 pins and leave two pins overhanging each side, only problem is..

1. The plastic chasis on the card wont allow it.
2. The 8 pin plug, when inserted the right way around, has a little bit of plastic connecting some of the pins not allowing it to fit in.

So what do i do?

Only outcome i can think of is, cut the little bit of plastic so the plug fits, and cut a small bit of the plastic chasis on the card. But would this work and is it safe?

Thanks, Ben.


PSU is a ThermalTake Tough Power 850w Sli Certified.

I don't think you should cut any plastic off to make it fit, because as far as I know, they were put there so no one messes up and plugs them into the wrong place, and your computer goes boom. I would wait for someone that knows more about the issue, but I wouldn't do it myself. Sounds unsafe. Its strange that an SLI certified PSU has only 2 PCI-E connectors. Are you sure?

I would check again to see if you have the 4 PCI-E connectors, or check if you have the right power supply because things aren't matching.

This is nice and easy, if it doesn't fit, it's not the right cable.

Well i have 2x 8 pin that are connected to the power, then i have two detatchable 6 pin pcie cables aswell.

Can i get an adapter to convert the 8 pin to a 6+2pin ?

Are you sure you cant snap the 2 extra away from the 6pin? On my power power supply I have 1 6pin and 1 8pin/6pin. You should be able to snap the last 2 pins away from the 6pin, try and brake the last 2 pins away from the 6pin. Do you understand what I am saying?

That sounds like an 8-pin CPU connector, not an 8-pin PCI-e connector.
Don't use that one.
