Silent 500W Power Supply

NightRyder writes "To cope with the increased power demands of today's processors and video cards a 500W silent power supply has been released by Antec. The topic of silent power production has been an important one to the computer community recently, especially concerning the increased hardware demands by new game and operating systems. Considering the processing demands of something like, *cough* Windows Vista, its important to be able to keep your computer cool without it getting loud."

There was a story about power supplies earlier

I remember that the story was discussing how the advertised wattages of these power supplies were pretty much lies or gross exaggerations. So we're talking about 500W of power without cooling, but how much power can be drawn until the thing dies from heat exhaustion? And can the 500W output be sustained for extended lengths of time?

Also, does anyone find really strange that slashdot would put the CSS definition files in the images.slashdot.org domain? One computer I use shows Slashdot completely stripped down. This one shows it "normally". Any way to get rid of advertisements and images without losing the formatting as well?

This fan is off most of the time but when the insides heat up it will be turned on until the temperature is below the set limit. When running, the fan's speed will vary automatically based on how hot the PSU is, so even it is running it may barely be audible because the fan is spinning slowly.

So they have mostly eliminated the need for a fan by using some good heat dissipation methods. Though if you are running your PC for extended periods of time or your PC is tucked away under a desk somewhere where it doesn't get much air flow, I would expect the fan to be humming away as normal.

It was Joe Betts, working at IBM Almaden Research Lab, who designed the first 90%+ efficient switching power-brick, for the Thinkpad. Before that, bricks were all twice as big, and ran hot-hot-hot. After that, all the other guys had to clean up their acts too. He didn't study electrical engineering in school, but he didn't let that slow him down; he learned what he needed when he needed it.

Nowadays he's at Oqo.

Well, you are unusual then. Noise affects people differently, but experiements show that for many people, a lot of ambient noise disturbs sleep, causing fewer REM periods. It can also damage your hearing over time.
