I trust my "homemade junk" over most of the power supplies at amain. I saw one of the older protec(?) ones with the red front panel overheat and nearly catch fire...
my "homemade junk" are used in servers that have $10000000000000000000000000 of dollars worth of info on them...
If you would like, I have a few power supplies similar to the HP one listed, except they are 50+ amps at 120v and 100+ at 240, all in a box that is smaller than most of the 20 amp ones at amain...I usually do 4 outputs, and all of the contacts are covered with black silicone. I charge $40 local for them, and shipping would be $15ish....
I use this charger...
