Some time ago, I ran across a website that listed the 5 or 6
main power supply manufacturers and the main brands they
produced for. The only one I remember was fortron.
www.directron.com/psu.html has a FAQ that's useless, but under "Notes"
it lists some actual manufacturers.
http://terasan.okiraku-pc.net/dengen/no99/index.html lists several
brands, some of them manufacturers.
www.overclockers.com has a power supply forum with some messages
containing FAQs.
Some manufactures I know of are:
FSP: Fortron, Source, Sparkle, Powerman, Hi-Q, Trend, Aopen. Most
but not all model numbers start with "FSP"
Delta: Acer, some OEM supplies. Models start with "DPS"
HEC: Heroichi, Compucase, older Antecs, including those with models
starting with "PP"
Topower: Toria, TTGI, maybe also Hiperpower and Superflower
Sirtec: Thermaltake, Vantec, High Power, Super Power, and maybe
Silver Stone Technology and Coolermaster.
Enermax: maybe Casemart and Wavesonic
Channel Well Technology: Antec, Lead Power. Except for Antec, model
numbers start with "CWT," but apparently another, much inferior, brand
uses this prefix as well.
Zippy-Emacs
Win-tact
Lite-On
Astec
2 manufactures to avoid:
Leadman: Powmax, Robanton, Raidmax
Deer: Allied, codegen, L&C, Logic, Foxconn, Mustang, Powerstar,
Eagle, Foxlink, Mercury, Duro, Austin, Turbolink, Real Power.
