Many 600W PSUs out there can't output 600W. The crap you see in most people's signatures here, even though they say "600W" or whatever, the reality is that it's only maybe half that continuous power, with an efficiency around the 70% range and so much dirty power that the DC output on a scope looks strikingly similar to the mating call of a humpback whale.

In other words, Dell's 300w will blow away these guys' crappy 600W units.

The same thing goes for stereos. There's crap watts (Pioneer, Sony, JVC, Kenwood, Panasonic, RCA, etc).. Those units are measured in PDP (Peak Distortion Power). Then there's real watts. Arcam, Nakamichi, Rotel, etc. The difference? RMS vs. peak.. and current, current, and more current. In PSUs, output voltage regulation is another key factor.. Something $30 PSUs skimp on to save a few bucks.

Some goof is sitting there with a multimeter, going "holy crap, you see that??? It just hit 600W".. right before the PSU melts... and 600W gets stamped on the unit. These kids in here that spent $30 on a 600W PSU.. They aren't 600W. That's "crap power" or "the max power I can possibly make for 10 seconds before I blow up and fry half your computer" power.
