Best (inexpensive) switcher power supply? WeiYa / Happ / Others?
I posted this in the ArcadeSD thread, but realize I have at least 4 circuit boards worth over $200 each being run by 15-20 year old used, dirty, switch-mode power supplies, some of which make noise, some swapped in when the previous older/dirtier one suddenly died or did someting strange. I realized that a $300 board should not be fed power from something that could potentially destroy it when it failed and though I should do a bulk buy of some power supplies to lower costs and help me sleep better
So, most of the basic 15A 5V supplies run about $25, and buy a few and you can keep prices around $24 to $28 including shipping, not bad to protect 10x-15x that in parts.
Looking around I see a few key supplies and was wondering what the experts (Ken and others) feel is worthy of my money:
1) WeiYa P03(C) or older WY-03(C) series? (not sure what is different) Neither seem to be CE/CUL "safety rated" though but the P03C does show CE on a pic but thats of the one with numeric LED
2) Suzo/Happ Power Pro 110 watt (has warning saying must have 1A draw on +5V -- which is an issue for the multi-boards, right? No warning on the WeiYa but docs are in Chinese)
3) Suzo/Happ Chinese clone? 104 watt (higher 12V (4A)) -- same output level warning
4) Suzo/Happ Power Pro 130 watt (higher 12V (4A)) -- again output level warning
5) "Min Dong"
6) Very Generic
