The problem is the PC cant even start with it inside, its like trying to start a car with a dead battery. It powers fine without the card. I guess the power supply is weak. Am I right to buy another more powerful power supply, any recommendation for one is welcome. Thanks
According to the output chart on the link you provided, it can supply a max of 516W. 516W / 12V = 43A. As the link also says, if the LED is lit you have a power failure. Double check your connections, and try again. If its plugged in correctly, you probably have a dead psu.
This is actually the second new PSU I am buying. I thought the problem was power related. Maybe the circuit is breaking cause of the Graphic card, I will try again not sure who is faulty, the graphic card spins for a split second then everything dies out. I will try and monitor when the light comes on. I dont think the problem should be with the cable powering the power supply. I will try again thanks
