The only ones I've had failures on, were the CWT (ChannelWell).

They have the usual spread, the low end is likely iffy, their
high end is better.

But after my experience, I'd really rather have someone else make the supply.

FSP (Fortron Sparkle), one of their characteristics, is the cable
length is "just barely enough". That's how you could tell one
of their OEMed units. I have one unit here branded "Sparkle"
and that might be FSP. The other thing about FSP, is their crossloading
spec, goes right out to the ATX spec max. They seemed to take
pride in doing that.

For a cheap one then, based on my failures here, I'd just want to
check whether they were ChannelWell or not. The FSP will be OK.
Enhance have made good stuff. Enermax, I've used a couple of those
for years (more than ten years).

We don't know who makes the $20 units. Those have all the protection
circuitry removed, and also the supply has no certifications (no TUV).
If such a supply has a 500W rating, then testing will show the
supply is actually a 350W unit. Attempts to draw 500W don't end well
in such a case. As a result, as long as you have some idea how
kit like that behaves, then go ahead, spend $20 on one :-)
