Zing and Jelly Bean have already listed few above, OCZ and Corsair.
I would also recommend Thermaltake (also listed above).
Other good
PSU's include Seasonic, Antec, Enermax, CoolMax, Zalman, Hiper and Silverstone < probably the most popular manufacturers.
Still high quality manufacturers however less popular include Seventeam, Emacs, iStarUSA, Norwood and PCP&C. That are others, definately not including Raidmax there... despite it's priddy little blue light!!
