Power Supply Comparisons
Sparkle Power International 350watt vs. 400watt PS comparison. Inital revision 26 January 2001.
Enermax, PC Power and Cooling, Antec, and Sparkle are the names heard most frequently among computer enthusiasts. Barring the standard sizes of 145, 200, 250, 300 and 400 watts, there are some oddball sizes. Enermax does 330 and 431 watt power supplies, while Sparkle has a 350watt PS.
First, some notes. According to jfh of coolcases.com and my own analysis, the Enermax 330 watt is really much closer to a 300 watt PS in terms of output. The 431 watt is closer to a 400 watt. That's something to chew on for people deciding between the 330 watt Enermax and the 350 watt Sparkle; in terms of quality and cooling Enermax may be top notch, but if you really need the extra power and don't have the money for a 400 watt, you will probably be better off with the Sparkle 350 watt. It should be noted that I am NOT a trained engineer, so do not expect detailed engineering to be touched in this comparison. I have a rudimentary understanding of electronics and circuits, but this is also being done from a computer geek perspective and is focused on what is visible, not what isn't.
On to the comparison. In short, the Sparkle 350 watt and 400 watt have similar combined (+3.3 and +5) loads of 220 and 235 watts, but the 400 watt has beefier internals. "Noise killer" fans mean nothing, both were definitely noticable when powered on.

Electronics is not my speciality, so this pictorial comparison is the best I can do. The Sparkle 350 watt has a very high combined load of 220 watts when compared to other 300 watt power supplies (Enermax 330 watt, Ya Hsin 300 watt, Antec 300 watt, etc.) and should be an excellent upgrade for those who are worried about maxing out their 300 watt power supplies. However, the Sparkle 400 watt has much beefier internals and is most definitely a "true" 400 watt power supply if its construction is at all informative of its abilities. Should you be running a highly stressed system with considerable power demands, the Sparkle 400 watt unit or other equivalents may be worth the upgrade.

Final notes: 26 January 2001: Pictures were not all taken at one time, as a result pictures are not as comprehensive as I would like. I currently have a Ya Hsin 300 watt PS in my possession as well as an Enermax 330 watt PS on the way. I may add those two PS'es to this comparison if time permits.
