just brew it! wrote:I've actually toyed half-seriously with the possibility of teaching myself enough about PC PSU design to roll my own. An "if you really want it done right, you've got to do it yourself" sort of deal. I've built a few regulated power supplies in the past, but they've all been relatively low power -- nowhere near the sort of wattage (or number of rails) that a PC PSU requires.
Unfortunately, the prospect of getting it wrong and frying a PC -- or even worse, creating an electrocution hazard -- has prevented me from following through on this idea...
Yeah, the extremes of dealing with insane voltage on one end and insane current on the other are daunting. I wouldn't ever roll my own at 50 watts, let alone 500.
