Will it be right to say this power supply has (19*3)= 57A combined power output or it is 19A ?

I have this graphics card requiring 146W which isnt been powered.

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

Is there a red switch on the back of the psu? If so switch it so all the rails act as a single rail.

There is no Red switch but a red light bulb which comes on when its powered, no switch at all you cant do anything with this its just a led bulb.

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
