How could I go about measuring the actual power consumption of a PC after it is built?
For example, if always use a 350w power supply, is that number the maximum it can supply? If my hardware specs are light (few if any PCI cards, integrated motherboard, Celeron 2.0GHz CPU), what am I actually using?
The reason that I am asking is because I want to use a reasonably sized, inexpensive UPS but do not want to create an unsafe condition. I am only trying to protect against brownouts and momentary power outages.
