I have seen reviews of the graphics card that say you don't need additional power. I was looking for some help to determine if I need to purchase a new power supply, and if so what Watt? and what brand is reliable. I was hoping to only spend around 80$ for the power supply if needed.
According to the specs for the PS you put out, it will put out 18 amps, but whether or not it will actually provide that, I don't know how to tell without test equipment. You can be pretty sure the best brands will output what they say they will, as they're tested by sites like Tom's and AnandTech all the time, but I'm unfamiliar with your brand and I suspect it is not top quality, else Dell would not be putting it in their PCs (Dell tends to compete on price).
