And evidently $50 + Inland + Microcenter does not equal a quality 650 Watt Power Supply.
The next 3d Printer will have a nice big, quiet, slow turning fan cooling the guts and a professional switch and conventional Computer Power Plug as a result.
Looking at the top of the board, I was surprised that all of the power supply lines were really tightly located together, I’d seen separation where the different sources come off the common rails on other supplies…
I then flipped the board over and…well…the quality kinda speaks for itself.
@Mike_Miller As far as SMPS the design goes it remains same for a long time . I Have seen SMPS with same PCB layout on 15years old to 3 month old ones. But makes it much easy to service the and salvage parts from it. I usually buy old SMPS from the Junkyard for 3$ per 10 pces. Most of the time i get lucky and 6 out of 10 work without any maintanence and 2-3 requires some work and 1 will be used for salwaging parts.
what has changed is fancy branding. however there are some serious websites that does PSU testing. and because of this, they get strong armed by some companies into NOT doing it, we all know why dont we? cos now we know some branded names are really lousy.
Well, it was obviously a failure of finding the optimal cost/quality point in the curve, plus buying not quire the right thing because I could source it locally.
I’m hoping the $25 regulated power supply recommended here from Amazon performs adequately…it’ll certainly be easier to route power to/from.
