A Kilowatt of Power 336
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.'"

The switcher immediatly converts the ac line current to dc and takes the ripple out using 2 or 3 big fat capacitors. Thats why it sparks when you plug a cold switcher in, the caps charge up. The dc then feeds a transistor which is controlled by an oscillator and produces a 20+ KHz square wave. This feeds some high frequency transformers that kick the power down to the necessary voltages like 3.3, 5, and 12 volts. Each voltage gets its own transformer, more caps to filter out the high frequency and then to regulators for each voltage. Thats the benefit of a switcher, light weight and compact for the power it converts(although more complex and only a 70-80% efficiency). On a side note: If you ever wonderd why aircraft use 400Hz power here is your answer, smaller and lighter power systems.
A linear would take the 120/240v line power at 60/50HZ and put it strait through a big fat transformer made for 50/60 hz and lower it to 3.3, 5 and 12 volts then each to a set of smoothing caps and regulators. A 1 kw linear would weigh oh id guess 20-30 pounds! The higher the frequency, the less turns of wire and smaller core a transformer requires. Plus it would be more efficent then a switcher.
Each of those power supplies have there respective efficiencies but in no way does the linear waste it as you imply. Please if you dont know what you are talking about then dont post misinformation.

It's not as gimmicky as it might seem. I sincerely HOPE nobody's desktop system actually draws a Kw, that's not the whole story. The closer a supply's output is to it's max rating, the more ripple there is and the more the voltages tend to sag. It also means the internal parts in the P/S will be running close to their max heat rating.
So, a power supply that never sees more than 50% of it's rated load will run cool and very stable and will have a long service life. Looking at the green aspects, this P/S won't end up taking space in a landfill next year.
