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.'"
A few days ago, I installed a Thermaltake TWV-480 in one of my machines. This is a power supply that inclues a front bay panel with an LCD display telling you how many watts of power are currently being used. The machine is a Pentium 4 2.4ghz with a Radeon 9600 Pro, a CD burner, four hard drives and several USB devices.
Since installing the panel, the machine idles around 50 watts or so, spikes up to perhaps 55 if I turn up the fan speeds (which is rarely necessary), and maybe 60-75 or so for a few brief moments when I'm doing something that requires heavy disk access like openning a large file (or group of files).
I can't possibly imagine that newer, more powerful hardware would consume a full two orders of magnitude more power than this machine, especially given the great work we've all heard being done recently in heat and power efficiency with AMD's newer chips Cool 'n' Quiet tech and Intels Pentium Ms. So given that, who needs this much power?
