Hello,
Heres the situation, I am trying to do two gtx570s in sli. Each 570 requires two 6 pin connectors, my psu only has enough connectors for one. I am aware that there are converters that use two 4 pin molex plugs and converts them into a 6 pin plug. Is it possible/safe to use two of these adapters on the one powersupply? Will the 570s still work properly?
cheers

Hi!
Using the adaptors won't be a problem, as long as your PSU can handle both cards (Total wattage and Amp. on the 12v rail).
What's your Current PSU?

A pair of GTX570's will draw about 30 amps together peaking to 40 amps (360 - 500 watts).

The specs in the link say you have a 600 watt power supply. "Peak" power ratings are meaningless.

Next, you have two 12 volt rails, one with a max rating of 30 amps, the other 22 amps. You do not have a max of 52 amps available. 52 amps equals 624 watts - clearly impossible.

The "peak" power rating tells me that you have a relatively poor power supply. I would not recommend trying to power 2 GTX570's.
