I found a cross-reference for power supply brands and OEM manufacturers. It’s a couple of years old, but still useful.
Way back when, I knew that Sparkle Power actually made PC Power & Cooling Silencer power supplies. Since Sparkle units were cheaper, I bought those, and got good, reliable power from them for years until they were obsolete. That information is obsolete now too; Sparkle was bought out by FSP many years ago.
This chart tells you a whole lot more than that. And it validates that my current practice of buying Seasonic power supplies whenever possible is probably good, since Seasonic is the actual maker for several premium brands of power supplies today.
