Logisys Meshed 500W PSU
 

The sticker on the underside states 28A on the 3.3V line, 38A on the 5V line, and 17A on the 12V line. While the first two are sufficient, 17A on the 12V rail isn't enough, considering other quality 300-400W models can provide as much as 30A. Even more interesting are the combined ratings. You'll notice there's a 200W power limit on the 3.3V + 5V rails. Furthermore, there's a 350W total power rating for all three rails, with the "max output" capped at 500W. In other words, you're not getting a 500W model. You're getting a 350W model that's theoretically capable of a 500W maximum output. The caveat here is that because the total power is written to be 350W, you can't expect to get sustained, stable power delivery beyond that. Fortunately for most people, even 300 watts is more than enough.
