Topower sues Asustek and other for PSU patent infringement
 

Topower Computer claims a patent for its 20+4 pin ATX power supply was approved in the US in September 2005. The company is looking to settle the infringement cases through patent royalty payments or strategic alliances for use of its patented power supply technology.

If money, man power and patience (time) are what you have; it will pay off. Before the 20+4; 20 to 24 converters were used. I wish Topower the best of luck. Get them bastards; Antec too.

it's not cool to copy somebody else's hard work -- :-/
