It depends entirely on the setup of your computer. An average desktop using a CPU with a low power draw, a single hard drive, no sound card and integrated graphics or a graphics card which doesn't require it's own power connectors will draw less than 300W. But today's top end system with high end CPUs which have been overclocked by a substantial amount, several hard drives, double, triple or even quadruple graphics card setups, all of which require their own power supplies, all manner of other PCI/PCI-E devices (Sound cards, NIC cards etc) not to mention several case fans/fan controllers/case lights/USB charging devices etc. can easily draw well over 1000W (1kw). However, you also have to take into account whether the wattage rating for the PSU is for peak output or continuous output (continuous output is better for same wattage rating), and the efficiency of the power supply (e.g. 400W output from a power supply would draw 500W from a wall socket if it is 80% efficient).
