Not necessarily, it just means it will pull power through the PCIe. That can work against you. your looking at full load consumption of around 75 watts for that card. If you have a 230W brick you can probably get away with it. You would be pushing the limits with just the CPU and GPU on a 180 watt brick. Keep in mind you should never run any power supply at a contant past 80% of its rated value. So 144 watts is the ceiling for the 180 watt brick and 184 watts for the 230 watt brick. The current will take as much as it can. You cant control current in a DC circuit as current is based off of difference of potential. The only way to change that is to change the volatge. In the end watts are watts. Voltage sags, current goes up, current goes up, heat goes up and the magic smoke gets out.
Just be sure to carefully calculate your power consumption for everything on the power supply.
The card doesnt have a power connection on it other than the PCIe so the kit for the second PSU wont do any justice.
