Coba King 420W
Googling coba power supply only returned 1 link in English in the first several pages that might be helpful http://www.tomshardware.com/howto/20021021/index.html
They tested a 350W version. The results were not outstanding, but it passed thier tests.
I imagine that if you google "coba power supply" there will be a number of pages in a language that you know.
