Power Supply Round-up @ NordicHardware

"As computers evolve they need more and more power to function as they are supposed to. There are many demands put on your power supply, and it is supposed to handle them to be good enough for your system. The first is of course that it is powerful enough, you want to avoid voltage fluctuations and drops."
There is really no rule of thumb for choosing a power supply though I'd say 350w is the minimum for any high performance computer.
