Question : Problem: Power Supply requirements for SLi?

Im looking at buying a power supply to support a gaming system in SLi or Crossfire. Does the power-supply NEED to be SLi certified? I was considering buying a Thermaltake TR2 W0070RUC 430W. Will that work...Any ideas?

Normally, you should check the power connector on video card, and look for the power supply that provides such connections so you dont need adapter. Some motherboard will have power connection to supply to video card as well.

500 W is still underpower. Use this free tool to calculate how much power supply you need:
