A Kilowatt of Power

An anonymous reader writes "There is finally a review available of a kilowatt power supply. The PC Power and Cooling 1KW produces 1000W of power output with 1100W peak. The review points out how great this product did in the testing but was not afraid to admit how much of an overkill it is for the enthusiast market. From the article, 'In the current computing world, where more always equals "better than" the 1KW is king.'"

No, sir, the power supply is a switcher, not a linear power supply. All computer power supplies are. They do not operate by continuously wasting power - instead they transform the line power into the desired voltage and current at around 88% efficiency (depending on the model) all the way from a minimal load to a full load. In fact, for a normal load, this power supply won't draw any more wall current than a 300 watt supply - but it will be able to draw a lot more if it needs to, without failing, if its claims are true.

Not trying to be an ass but it hurts the eyes when so many posts including opening article have kW wrong. It is kW not KW. It has a small k because kilo isn't taken from somebody's name.


I found a list of metric prefixes.

I have no idea why Kilo is not uppercase as are most multiplyers of greater than unity. In common pratice is is common for greater then unity multiplyers to be uppercase to avoid confusion with less then unity multiplyers. That is why most street signs read KM to the next exit and transistors are measured in nm and leakage current is measured in uA.
