A couple more power supplies, quite attractive and relatively well made, at least on the outside, but with typical Chinese "quirks" in exaggerated form—at least one of them has them.

You can never have too many power supplies. That’s what I thought, too, so today I’m taking a quick look at four compact sealed power supplies, plus a bonus fifth one. It’s not exactly compact, but it is sealed. And that’s not the end of the bonuses—look for more near the end of the article :)

These are the last power supplies in this form factor to come my way for testing—for now, at least. I doubt they’ll be the last in the long run. They left me with mixed feelings: not bad, but with a few “caveats.” As always, more details in the review.

Another installment in my series of reviews of various power supplies. This time, I’m looking at boards from sealed power supplies rated at 60, 100, 150, 200 and 300 W. I think you’ll find it interesting.
