Learn many things, 1. Keep a bulb to check it out at the store. 2. 1mA precision is applicational needed when designing. 3. Check the fan system, load and see it's functional before buying, or else buy an expensive one with a warranty. 4. Bring your oscilloscope to check for some ripple( if buying without warranty ). 5. Check that it's made up with galvanic isolation. Even it's a SMPS mode, If have enough isolation then it's oky. 6. Output wires should not design to just carry maximum current, that's their rated value. In transients, it can get more current, so wires should be thicker than that. 7. Check for some noise, not only you will hate it while working. But if made with flyback or transformer, that means a serious issue there. Need an expensive repair. 8. Vibrate a little and check whether internal parts are mounted correctly,( this was happened to me). 9. check no smell near the fan while loading it up. Any more to be included into this checklist on buying a power supply without warranty?
